       This man page documents lftp version 4.0.4.


       lftp is a file transfer program that allows sophisticated ftp, http and
       other connections to other hosts. If site is specified then  lftp  will
       connect  to that site otherwise a connection has to be established with
       the open command.

       lftp can handle several file access methods - ftp, ftps,  http,  https,
       hftp,  fish, sftp and file (https and ftps are only available when lftp
       is compiled with GNU TLS or  OpenSSL  library).  You  can  specify  the
       method    to    use    in    ‘open    URL’    command,    e.g.    ‘open’.   hftp   is    ftp-over-http-proxy
       protocol.  It  can be used automatically instead of ftp if ftp:proxy is
       set to ‘http://proxy[:port]’. Fish is a protocol working  over  an  ssh
       connection to a unix account. SFtp is a protocol implemented in ssh2 as
       sftp subsystem.

       Besides FTP-like protocols, lftp has support for BitTorrent protocol as
       ‘torrent’ command. Seeding is also supported.

       Every  operation  in  lftp  is reliable, that is any not fatal error is
       ignored and the operation is repeated. So  if  downloading  breaks,  it
       will be restarted from the point automatically. Even if ftp server does
       not support REST command, lftp will try to retrieve the file  from  the
       very beginning until the file is transferred completely.

       lftp  has  shell-like  command  syntax  allowing  you to launch several
       commands in parallel in background (&). It is also  possible  to  group
       commands  within () and execute them in background. All background jobs
       are executed in the same single process. You can bring a foreground job
       to background with ^Z (c-z) and back with command ‘wait’ (or ‘fg’ which
       is alias to ‘wait’). To list running jobs,  use  command  ‘jobs’.  Some
       commands  allow  redirecting their output (cat, ls, ...) to file or via
       pipe to external command. Commands can be executed conditionally  based
       on termination status of previous command (&&, ||).

       If  you  exit  lftp when some jobs are not finished yet, lftp will move
       itself to nohup mode in background. The same happens when  you  have  a
       real modem hangup or when you close an xterm.

       lftp  has builtin mirror which can download or update a whole directory
       tree. There is also reverse mirror (mirror -R) which uploads or updates
       a  directory  tree  on  server. Mirror can also synchronize directories
       between two remote servers, using FXP if available.

       There is command ‘at’ to launch a job  at  specified  time  in  current
       context, command ‘queue’ to queue commands for sequential execution for
       current server, and much more.

       On  startup,  lftp  executes  /etc/lftp.conf  and  then  ~/.lftprc  and
       ~/.lftp/rc. You can place aliases and ‘set’ commands there. Some people
       prefer to see full protocol debug, use ‘debug’ to turn  the  debug  on.
       Use ‘debug 3’ to see only greeting messages and error messages.

       lftp  has  a  number of settable variables. You can use ‘set -a’ to see
       all variables and their values or ‘set -d’ to  see  list  of  defaults.
       Variable  names can be abbreviated and prefix can be omitted unless the
       rest becomes ambiguous.

       If lftp was compiled with OpenSSL (configure --with-openssl),  then  it
       includes  software  developed  by  the  OpenSSL  Project for use in the
       OpenSSL Toolkit. (

       ! shell command

       Launch shell or shell command.


       To do a directory listing of the local host.

       alias  [name [value]]

       Define or undefine alias name.  If  value  is  omitted,  the  alias  is
       undefined,  else  it takes the value value. If no argument is given the
       current aliases are listed.

            alias dir ls -lF
            alias less zmore


       Sets the user to anonymous.  This is the default.

       at time [ -- command ]

       Wait until the given time and execute  given  (optional)  command.  See
       also at(1).

       bookmark  [subcommand]

       The bookmark command controls bookmarks.
            add <name> [<loc>]  add current place or given location
                           to bookmarks and bind to given name
            del <name>          remove bookmark with name
            edit           start editor on bookmarks file
            import <type>       import foreign bookmarks
            list           list bookmarks (default)

       cache  [subcommand]

       The   cache   command  controls  local  memory  cache.   The  following
       subcommands are recognized:
            stat           print cache status (default)
            on|off              turn on/off caching
            flush               flush cache
            size lim            set memory limit, -1 means unlimited
            expire Nx      set cache expiration time to N seconds (x=s)
                           minutes (x=m) hours (x=h) or days (x=d)

       cat files

       cat outputs the remote file(s) to stdout.  (See  also  more,  zcat  and

       cd rdir

       Change  current  remote  directory.   The  previous remote directory is
       stored as ‘-’. You can do ‘cd -’ to change  the  directory  back.   The
       previous  directory for each site is also stored on disk, so you can do
       ‘open site; cd -’ even after lftp restart.

       chmod mode files

       Change permission mask on remote files.  The  mode  must  be  an  octal

       close [-a]

       Close  idle  connections.  By default only with the current server, use
       -a to close all idle connections.

       cls [OPTS] files...

       ‘cls’  tries  to  retrieve  information  about   specified   files   or
       directories  and  outputs  the information according to format options.
       The difference between ‘ls’ and ‘cls’ is that ‘ls’ requests the  server
       to  format  file listing, and ‘cls’ formats it itself, after retrieving
       all the needed information.  See ‘help cls’ for options.

       command cmd args...

       execute given command ignoring aliases.

       debug [-o file] level|off

       Switch debugging to level or turn it off.  Use -o to redirect the debug
       output to a file.

       echo [-n] string

       guess what it does.

       eval [-f format ] args...

       without  -f  it  just  executes  given arguments as a command. With -f,
       arguments are transformed into a new command. The  format  can  contain
       plain  text  and  placeholders  $0...$9  and  $@,  corresponding to the

       exit [bg] [top] [kill] [code]

       exit will exit from lftp or move to  background  if  there  are  active
       jobs. If no job is active, code is passed to operating system as lftp’s
       termination status. If code is omitted, the exit code of  last  command
       is used.

       ‘exit  bg’  forces  moving  to  background  when cmd:move-background is
       false.  ‘exit top’ makes  top  level  ‘shell’  (internal  lftp  command
       executor)  terminate.   ‘exit  kill’  kills  all  numbered  jobs before
       exiting. The options can be combined, e.g.  ‘at 08:00 -- exit top  kill
       &’ kills all jobs and makes lftp exit at specified time.


       Alias for ‘wait’.

       find  [directory]

       List files in the directory (current directory by default) recursively.
       This can help with servers lacking ls  -R  support.  You  can  redirect
       output of this command.


       Obsolete. Use one of the following instead:
            get ftp://... -o ftp://...
            get -O ftp://... file1 file2...
            put ftp://...
            mput ftp://.../*
            mget -O ftp://... ftp://.../*
       or  other  combinations  to  get FXP transfer (directly between two ftp
       servers).  lftp would fallback  to  plain  copy  (via  client)  if  FXP
       transfer cannot be initiated or ftp:use-fxp is false.

       get [-E] [-a] [-c] [-O base] rfile [-o lfile] ...

       Retrieve  the  remote  file rfile and store it as the local file lfile.
       If -o is omitted, the file is stored to local file named as  base  name
       of  rfile.  You can get multiple files by specifying multiple instances
       of rfile (and -o lfile). Does not expand wildcards, use mget for  that.
            -c        continue, reget
            -E        delete source files after successful transfer
            -a        use ascii mode (binary is the default)
            -O <base> specifies base directory or URL where files should be placed

            get README
            get README -o debian.README
            get README README.mirrors
            get README -o debian.README README.mirrors -o debian.mirrors
            get README -o
            get README -o (end slash is important)

       get1 [OPTS] rfile

       Transfer a single file. Options:
            -o <lfile>     destination file name (default - basename of rfile)
            -c        continue, reget
            -E        delete source files after successful transfer
            -a        use ascii mode (binary is the default)
                      transfer specified region of source file
                      position in target file to write data at

       glob [-d] [-a] [-f] command patterns

       Glob  given patterns containing metacharacters and pass result to given
       command.  E.g. ‘‘glob echo *’’.
            -f   plain files (default)
            -d   directories
            -a   all types

       help [cmd]

       Print help for cmd or if no cmd was specified print a list of available

       jobs [-v]

       List running jobs. -v means verbose, several -v can be specified.

       kill all|job_no

       Delete specified job with job_no or all jobs.  (For job_no see jobs)

       lcd ldir

       Change  current  local  directory ldir. The previous local directory is
       stored as ‘-’. You can do ‘lcd -’ to change the directory back.


       Print current working directory on local machine.

       ls params

       List remote files. You can redirect output of this command to  file  or
       via  pipe to external command.  By default, ls output is cached, to see
       new listing use rels or cache flush.

       mget [-c] [-d] [-a] [-E] [-O base] files

       Gets selected files with expanded wildcards.

            -c        continue, reget.
            -d        create directories the same as file names and get
                      the files into them instead of current directory.
            -E        delete source files after successful transfer
            -a        use ascii mode (binary is the default)
            -O <base> specifies base directory or URL where files should be placed

       mirror [OPTS] [source [target]]

       Mirror specified source directory to local target directory. If  target
       directory ends with a slash, the source base name is appended to target
       directory  name.  Source  and/or  target  can  be  URLs   pointing   to

            -c, --continue      continue a mirror job if possible
            -e, --delete        delete files not present at remote site
                --delete-first       delete old files before transferring new ones
                --depth-first        descend into subdirectories before transferring files
            -s, --allow-suid         set suid/sgid bits according to remote site
                --allow-chown   try to set owner and group on files
                --ascii         use ascii mode transfers (implies --ignore-size)
                --ignore-time        ignore time when deciding whether to download
                --ignore-size        ignore size when deciding whether to download
                --only-missing  download only missing files
                --only-existing download only files already existing at target
            -n, --only-newer    download only newer files (-c won’t work)
                --no-empty-dirs don’t create empty directories (implies --depth-first)
            -r, --no-recursion  don’t go to subdirectories
                --no-symlinks   don’t create symbolic links
            -p, --no-perms      don’t set file permissions
                --no-umask      don’t apply umask to file modes
            -R, --reverse       reverse mirror (put files)
            -L, --dereference   download symbolic links as files
            -N, --newer-than=SPEC    download only files newer than specified time
                --on-change=CMD      execute the command if anything has been changed
                --older-than=SPEC    download only files older than specified time
                --size-range=RANGE   download only files with size in specified range
            -P, --parallel[=N]  download N files in parallel
                --use-pget[-n=N]     use pget to transfer every single file
                --loop          loop until no changes found
            -i RX, --include RX include matching files
            -x RX, --exclude RX exclude matching files
            -I GP, --include-glob GP include matching files
            -X GP, --exclude-glob GP exclude matching files
            -v, --verbose[=level]    verbose operation
                --log=FILE      write lftp commands being executed to FILE
                --script=FILE        write lftp commands to FILE, but don’t execute them
                --just-print, --dry-run   same as --script=-
                --use-cache          use cached directory listings
            --Remove-source-files    remove files after transfer (use with caution)
            -a             same as --allow-chown --allow-suid --no-umask

       When  using  -R, the first directory is local and the second is remote.
       If the second directory is omitted, base name  of  first  directory  is
       used.   If  both  directories  are  omitted,  current  local and remote
       directories are used.  If target directory ends with  a  slash  (except
       root directory) then base name of source directory is appended.

       RX is an extended regular expression, just like in egrep(1).

       GP is a glob pattern, e.g. ‘*.zip’.

       Include  and  exclude options can be specified multiple times. It means
       that a file or directory would be mirrored if it matches an include and
       does  not  match  to  excludes  after  the  include,  or does not match
       anything and the first check is exclude. Directories are matched with a
       slash appended.

       Note  that  symbolic  links  are  not  created when uploading to remote
       server, because ftp protocol cannot do it. To upload  files  the  links
       refer to, use ‘mirror -RL’ command (treat symbolic links as files).

       For  option  --newer-than  you  can  either  specify  a  file  or  time
       specification like that used by  at(1)  command,  e.g.  ‘now-7days’  or
       ‘week  ago’. If you specify a file, then modification time of that file
       will be used.

       Verbosity level can be selected  using  --verbose=level  option  or  by
       several -v options, e.g. -vvv. Levels are:
            0 - no output (default)
            1 - print actions
            2 - +print not deleted file names (when -e is not specified)
            3 - +print directory names which are mirrored

       --only-newer  turns off file size comparison and uploads/downloads only
       newer files even if size is  different.  By  default  older  files  are
       transferred and replace newer ones.

       You  can  mirror  between  two  servers  if you specify URLs instead of
       directories.  FXP is  used  automatically  for  transfers  between  ftp
       servers, if possible.

       Some  ftp  servers hide dot-files by default (e.g. .htaccess), and show
       them only when LIST command is used with -a option. In such case try to
       use ‘set ftp:list-options -a’.

       mkdir [-p] dir(s)

       Make remote directories. If -p is used, make all components of paths.

       module module [ args ]

       Load  given  module  using  dlopen(3) function. If module name does not
       contain a slash, it is searched in directories specified by module:path
       variable.    Arguments   are   passed   to  module_init  function.  See
       README.modules for technical details.

       more files

       Same as ‘cat files | more’. if PAGER is set,  it  is  used  as  filter.
       (See also cat, zcat and zmore)

       mput [-c] [-d] [-a] [-E] [-O base] files

       Upload  files with wildcard expansion. By default it uses the base name
       of local name as remote one. This can be changed by ‘-d’ option.
            -c        continue, reput
            -d        create directories the same as in file names and put the
                      files into them instead of current directory
            -E        delete source files after successful transfer (dangerous)
            -a        use ascii mode (binary is the default)
            -O <base> specifies base directory or URL where files should be placed

       mrm file(s)

       Same as ‘glob rm’. Removes specified file(s) with wildcard expansion.

       mv file1 file2

       Rename file1 to file2.

       nlist [args]

       List remote file names

       open [-e cmd] [-u user[,pass]] [-p port] host|url

       Select an ftp server.

       pget [OPTS] rfile [-o lfile]

       Gets the specified file using several connections. This  can  speed  up
       transfer,  but  loads the net and server heavily impacting other users.
       Use only if you really have to transfer the file ASAP.  Options:
            -c        continue transfer. Requires lfile.lftp-pget-status file.
            -n maxconn     set maximum number of connections (default is taken from pget:default-n setting)

       put [-E] [-a] [-c] [-O base] lfile [-o rfile]

       Upload lfile with remote name rfile. If -o omitted, the  base  name  of
       lfile  is  used as remote name. Does not expand wildcards, use mput for
            -o <rfile>     specifies remote file name (default - basename of lfile)
            -c        continue, reput
                      it requires permission to overwrite remote files
            -E        delete source files after successful transfer (dangerous)
            -a        use ascii mode (binary is the default)
            -O <base> specifies base directory or URL where files should be placed

       pwd [-p]

       Print current remote URL. Use ‘-p’ option to show password in the  URL.

       queue [-n num ] cmd

       Add  the given command to queue for sequential execution. Each site has
       its own queue. ‘-n’ adds the command  before  the  given  item  in  the
       queue.  Don’t try to queue ‘cd’ or ‘lcd’ commands, it may confuse lftp.
       Instead do the cd/lcd before ‘queue’ command, and it will remember  the
       place in which the command is to be done. It is possible to queue up an
       already running job by ‘queue wait <jobno>’, but the job will  continue
       execution even if it is not the first in queue.

       ‘queue stop’ will stop the queue, it will not execute any new commands,
       but already running jobs will continue to run. You can use ‘queue stop’
       to  create  an  empty  stopped  queue.  ‘queue start’ will resume queue
       execution.  When you exit  lftp,  it  will  start  all  stopped  queues

       ‘queue’  with  no arguments will either create a stopped queue or print
       queue status.

       queue --delete|-d [index or wildcard expression]

       Delete one or more items from the queue. If no argument is  given,  the
       last entry in the queue is deleted.

       queue --move|-m <index or wildcard expression> [index]

       Move  the given items before the given queue index, or to the end if no
       destination is given.

            -q   Be quiet.
            -v   Be verbose.
            -Q   Output in a format that can be used to re-queue.
                 Useful with --delete.

            queue -d 3          Delete the third item in the queue.
            queue -m 6 4        Move the sixth item in the queue before the fourth.
            queue -m "get*zip" 1     Move all commands matching "get*zip" to the beginning
                           of the queue.  (The order of the items is preserved.)
            queue -d "get*zip"  Delete all commands matching "get*zip".

       quote cmd

       For FTP - send the command uninterpreted. Use with  caution  -  it  can
       lead  to unknown remote state and thus will cause reconnect. You cannot
       be sure that any change of remote state because of  quoted  command  is
       solid - it can be reset by reconnect at any time.

       For   HTTP  -  specific  to  HTTP  action.  Syntax:  ‘‘quote  <command>
       [<args>]’’.  Command may be ‘‘set-cookie’’ or ‘‘post’’.
            quote set-cookie "variable=value; othervar=othervalue"
            set http:post-content-type application/x-www-form-urlencoded
            quote post /cgi-bin/script.cgi "var=value&othervar=othervalue" > local_file

       For FISH - send the command uninterpreted. This can be used to  execute
       arbitrary  commands on server. The command must not take input or print
       ### at new line beginning. If it does, the protocol will become out  of
            open fish://server
            quote find -name \*.zip

       reget rfile [-o lfile]

       Same as ‘get -c’.

       rels [args]

       Same as ‘ls’, but ignores the cache.

       renlist [args]

       Same as ‘nlist’, but ignores the cache.

       repeat [ -c <count>] [[-d] delay] [command]

       Repeat  the  command.  Between  the  commands  a  delay is inserted, by
       default 1 second.  Option ‘-c’  limits  number  of  repeations.  Option
       ‘--while-ok’  breaks  loop  when  command  returns  non-zero exit code;
       ‘--until-ok’ breaks on zero exit code.
            repeat at tomorrow -- mirror
            repeat 1d mirror

       reput lfile [-o rfile]

       Same as ‘put -c’.

       rm [-r] [-f] files

       Remove remote files.  Does not expand wildcards, use mrm for  that.  -r
       is  for recursive directory remove. Be careful, if something goes wrong
       you can lose files. -f suppress error messages.

       rmdir dir(s)

       Remove remote directories.

       scache [session]

       List cached sessions or switch to specified session.

       set [var [val]]

       Set variable to given  value.  If  the  value  is  omitted,  unset  the
       variable.  Variable name has format ‘‘name/closure’’, where closure can
       specify exact application of the setting. See below  for  details.   If
       set  is  called with no variable then only altered settings are listed.
       It can be changed by options:

            -a   list all settings, including default values
            -d   list only default values, not necessary current ones

       site site_cmd

       Execute site command site_cmd and output the result.  You can  redirect
       its output.

       sleep interval

       Sleep  given time interval and exit. Interval is in seconds by default,
       but can be suffixed with ’m’, ’h’, ’d’  for  minutes,  hours  and  days
       respectively.  See also at.

       slot [name]

       Select  specified  slot  or  list  all  slots  allocated.  A  slot is a
       connection to a server, somewhat like a virtual console. You can create
       multiple  slots connected to different servers and switch between them.
       You can also use slot:name as a  pseudo-URL  evaluating  to  that  slot

       Default readline binding allows quick switching between slots named 0-9
       using Meta-0 - Meta-9 keys (often you can use Alt instead of Meta).

       source file
       source -e command

       Execute commands  recorded  in  file  file  or  returned  by  specified
       external command.
            source ~/.lftp/rc
            source -e echo help


       Stop  lftp  process. Note that transfers will be also stopped until you
       continue the process with shell’s fg or bg commands.

       torrent torrent-file [-O directory]

       Start BitTorrent process for the given torrent-file,  which  can  be  a
       local  file  or URL. Existing files are first validated. Missing pieces
       are downloaded. Files are stored  in  specified  directory  or  current
       working  directory  by  default.  Seeding  continues until ratio reachs
       torrent:stop-on-ratio setting or time of torrent:seed-max-time outs.

       user user [pass]
       user URL [pass]

       Use specified info for remote login. If you specify an  URL  with  user
       name, the entered password will be cached so that future URL references
       can use it.


       Print lftp version.

       wait [jobno]
       wait all

       Wait for specified job to terminate. If jobno is omitted, wait for last
       backgrounded job.

       ‘wait all’ waits for all jobs termination.

       zcat files

       Same as cat, but filter each file through zcat. (See also cat, more and

       zmore files

       Same as more, but filter each file through zcat. (See  also  cat,  zcat
       and more)

       On  startup,  lftp  executes  ~/.lftprc  and ~/.lftp/rc.  You can place
       aliases and ‘set’ commands  there.  Some  people  prefer  to  see  full
       protocol debug, use ‘debug’ to turn the debug on.

       There  is also a system-wide startup file in /etc/lftp.conf.  It can be
       in different directory, see FILES section.

       lftp has the following settable variables (you can also use ‘set -a’ to
       see all variables and their values):

       bmk:save-passwords (boolean)
              save plain text passwords in ~/.lftp/bookmarks on ‘bookmark add’
              command.  Off by default.

       cmd:at-exit (string)
              the commands in string are executed before lftp exits.

       cmd:csh-history (boolean)
              enables csh-like history expansion.

       cmd:default-protocol (string)
              The value is used when  ‘open’  is  used  with  just  host  name
              without protocol. Default is ‘ftp’.

       cmd:fail-exit (boolean)
              if true, exit when an unconditional (without || and && at begin)
              command fails.

       cmd:long-running (seconds)
              time of command execution, which is considered as ‘long’  and  a
              beep is done before next prompt. 0 means off.

       cmd:ls-default (string)
              default ls argument

       cmd:move-background (boolean)
              when  false,  lftp  refuses to go to background when exiting. To
              force it, use ‘exit bg’.

       cmd:move-background-detach (boolean)
              when true (default),  lftp  detaches  itself  from  the  control
              terminal when moving to background, it is not possible to attach
              back; when  false,  lftp  tricks  the  shell  to  move  lftp  to
              background  process  group  and  continues to run, then fg shell
              command brings lftp back to foreground unless it  has  done  all
              jobs and terminated.

       cmd:prompt (string)
              The  prompt.  lftp  recognizes  the  following backslash-escaped
              special characters that are decoded as follows:

              \@     insert @ if current user is not default
              \a     an ASCII bell character (07)
              \e     an ASCII escape character (033)
              \h     the hostname you are connected to
              \n     newline
              \s     the name of the client (lftp)
              \S     current slot name
              \u     the username of the user you are logged in as
              \U     the     URL     of     the     remote     site     (e.g.,
              \v     the version of lftp (e.g., 2.0.3)
              \w     the current working directory at the remote site
              \W     the  base  name  of  the current working directory at the
                     remote site
              \nnn   the character corresponding to the octal number nnn
              \\     a backslash
              \?     skips next character if previous substitution was  empty.
              \[     begin  a sequence of non-printing characters, which could
                     be used to embed a terminal  control  sequence  into  the
              \]     end a sequence of non-printing characters

       cmd:parallel (number)
              Number  of  jobs  run  in  parallel in non-interactive mode. For
              example, this may be useful  for  scripts  with  multiple  ‘get’
              commands.  Note  that  setting  this  to  a value greater than 1
              changes conditional  execution  behaviour,  basically  makes  it

       cmd:queue-parallel (number)
              Number of jobs run in parallel in a queue.

       cmd:time-style (string)
              This setting is the default value for cls --time-style option.

       cmd:trace (boolean)
              when true, lftp prints the commands it executes (like sh -x).

       cache:cache-empty-listings (boolean)
              When false, empty listings are not cached.

       cache:enable (boolean)
              When false, cache is disabled.

       cache:expire (time interval)
              Positive cache entries expire in this time interval.

       cache:expire-negative (time interval)
              Negative cache entries expire in this time interval.

       cache:size (number)
              Maximum  cache size. When exceeded, oldest cache entries will be
              removed from cache.

       cmd:remote-completion (boolean)
              a boolean to control whether or not lftp uses remote completion.

       cmd:verify-host (boolean)
              if  true, lftp resolves host name immediately in ‘open’ command.
              It is also possible to  skip  the  check  for  a  single  ‘open’
              command if ‘&’ is given, or if ^Z is pressed during the check.

       cmd:verify-path (boolean)
              if true, lftp checks the path given in ‘cd’ command.  It is also
              possible to skip the check for a single ‘cd’ command if  ‘&’  is
              given, or if ^Z is pressed during the check.  Examples:
                   set cmd:verify-path/hftp://* false
                   cd directory &

       cmd:verify-path-cached (boolean)
              When  false,  ‘cd’  to  a directory known from cache as existent
              will  succeed  immediately.   Otherwise  the  verification  will
              depend on cmd:verify-path setting.

       color:use-color (boolean)
              when  true,  cls  command  and  completion  output  colored file
              listings according to color:dir-colors setting.

       color:dir-colors (string)
              file  listing  color  description.  By  default  the  value   of
              LS_COLORS environment variable is used. See dircolors(1).

       dns:SRV-query (boolean)
              query for SRV records and use them before gethostbyname. The SRV
              records are only used if port is not explicitly  specified.  See
              RFC2052 for details.

       dns:cache-enable (boolean)
              enable  DNS  cache.  If  it is off, lftp resolves host name each
              time it reconnects.

       dns:cache-expire (time interval)
              time  to  live  for   DNS   cache   entries.   It   has   format
              <number><unit>+,  e.g.   1d12h30m5s  or  just  36h.  To  disable
              expiration, set it to ‘inf’ or ‘never’.

       dns:cache-size (number)
              maximum number of DNS cache entries.

       dns:fatal-timeout (time interval)
              limit the time for DNS queries. If DNS server is unavailable too
              long,  lftp  will  fail  to  resolve  a  given host name. Set to
              ‘never’ to disable.

       dns:order (list of protocol names)
              sets the order of DNS queries. Default is ‘‘inet6  inet’’  which
              means  first  look up address in inet6 family, then inet and use
              them in that order.  To disable inet6 (AAAA)  lookup,  set  this
              variable to ‘‘inet’’.

       dns:use-fork (boolean)
              if  true,  lftp will fork before resolving host address. Default
              is true.

       dns:max-retries (number)
              If zero, there is no limit on the number of times lftp will  try
              to lookup an address.  If > 0, lftp will try only this number of
              times to look up an address of each address family in dns:order.

       file:charset (string)
              local character set. It is set from current locale initially.

       fish:charset (string)
              the  character  set used by fish server in requests, replies and
              file listings.  Default is empty which means the same as  local.

       fish:connect-program (string)
              the  program  to  use for connecting to remote server. It should
              support ‘-l’ option for user name, ‘-p’ for port number. Default
              is ‘ssh -a -x’. You can set it to ‘rsh’, for example.

       fish:shell (string)
              use  specified shell on server side. Default is /bin/sh. On some
              systems,  /bin/sh  exits  when  doing  cd  to   a   non-existent
              directory.  lftp can handle that but it has to reconnect. Set it
              to /bin/bash for such systems if bash is installed.

       ftp:acct (string)
              Send this string in ACCT command  after  login.  The  result  is
              ignored.  The closure for this setting has format user@host.

       ftp:anon-pass (string)
              sets  the password used for anonymous ftp access authentication.
              Default is "-name@", where name is  the  username  of  the  user
              running the program.

       ftp:anon-user (string)
              sets the user name used for anonymous ftp access authentication.
              Default is "anonymous".

       ftp:auto-sync-mode (regex)
              if first server message matches this regex, turn  on  sync  mode
              for that host.

       ftp:charset (string)
              the  character  set  used by ftp server in requests, replies and
              file listings.  Default is empty which means the same as  local.
              This setting is only used when the server does not support UTF8.

       ftp:client (string)
              the name of ftp client to send with CLNT command,  if  supported
              by server.  If it is empty, then no CLNT command will be sent.

       ftp:bind-data-socket (boolean)
              bind  data  socket  to  the  interface of control connection (in
              passive mode).  Default  is  true,  exception  is  the  loopback

       ftp:fix-pasv-address (boolean)
              if true, lftp will try to correct address returned by server for
              PASV command in case when server address is  in  public  network
              and PASV returns an address from a private network. In this case
              lftp would substitute server address instead of the one returned
              by  PASV  command, port number would not be changed.  Default is

       ftp:fxp-passive-source (boolean)
              if true, lftp will try to set up source ftp  server  in  passive
              mode  first,  otherwise destination one. If first attempt fails,
              lftp  tries  to  set  them  up  the  other  way.  If  the  other
              disposition  fails  too, lftp falls back to plain copy. See also

       ftp:home (string)
              Initial directory. Default is empty string which means auto. Set
              this  to  ‘/’ if you don’t like the look of %2F in ftp URLs. The
              closure for this setting has format user@host.

       ftp:ignore-pasv-address (boolean)
              If true, lftp uses control connection address instead of the one
              returned  in  PASV reply for data connection. This can be useful
              for broken NATs.  Default is false.

       ftp:list-empty-ok (boolean)
              if set to false, empty lists from LIST command will  be  treated
              as incorrect, and another method (NLST) will be used.

       ftp:list-options (string)
              sets  options  which are always appended to LIST command. It can
              be useful to set this to  ‘-a’  if  server  does  not  show  dot
              (hidden) files by default.  Default is empty.

       ftp:nop-interval (seconds)
              delay  between  NOOP  commands  when downloading tail of a file.
              This is useful for ftp servers which  send  "Transfer  complete"
              message  before  flushing  data  transfer.  In  such  cases NOOP
              commands can prevent connection timeout.

       ftp:passive-mode (boolean)
              sets passive ftp mode. This can be useful if you  are  behind  a
              firewall  or  a  dumb  masquerading router. In passive mode lftp
              uses PASV command, not the PORT command which is used in  active
              mode.  In  passive mode lftp itself makes the data connection to
              the server; in active mode the server connects to lftp for  data
              transfer. Passive mode is the default.

       ftp:port-ipv4 (ipv4 address)
              specifies  an IPv4 address to send with PORT command. Default is
              empty which means to send the address of local  end  of  control

       ftp:port-range (from-to)
              allowed  port  range  for  active  mode.   Format is min-max, or
              ‘full’ or ‘any’ to indicate any port. Default is ‘full’.

       ftp:prefer-epsv (boolean)
              use EPSV as preferred passive mode. Default is ‘false’.

       ftp:proxy (URL)
              specifies ftp proxy to use.  To disable proxy set this to  empty
              string.  Note  that  it is an ftp proxy which uses ftp protocol,
              not ftp over http.  Default  value  is  taken  from  environment
              variable  ftp_proxy  if  it  starts with ‘‘ftp://’’. If your ftp
              proxy requires authentication, specify user name and password in
              the  URL.   If  ftp:proxy starts with http:// then hftp protocol
              (ftp over http proxy) is used instead of ftp automatically.

       ftp:proxy-auth-type (string)
              When       set       to       ‘‘joined’’,       lftp       sends
              ‘‘’’  as  user name to proxy, and
              ‘‘password@proxy_password’’ as password.

              When set to ‘‘joined-acct’’, lftp  sends  ‘‘
              proxy_user’’  (with  space)  as  user  name  to  proxy. The site
              password is sent as usual and the proxy password is expected  in
              the following ACCT command.

              When  set  to  ‘‘open’’,  lftp  first sends proxy user and proxy
              password and then ‘‘OPEN’’  followed  by  ‘‘USER
              user’’.  The site password is then sent as usual.

              When  set to ‘‘user’’ (default), lftp first sends proxy user and
              proxy password and then ‘‘’’ as  user  name.
              The site password is then sent as usual.

              When   set  to  ‘‘proxy-user@host’’,  lftp  first  sends  ‘‘USER
    ’’, then proxy password. The site user
              and password are then sent as usual.

       ftp:rest-list (boolean)
              allow  usage  of REST command before LIST command. This might be
              useful for large directories,  but  some  ftp  servers  silently
              ignore REST before LIST.

       ftp:rest-stor (boolean)
              if false, lftp will not try to use REST before STOR. This can be
              useful for some buggy servers which corrupt  (fill  with  zeros)
              the file if REST followed by STOR is used.

       ftp:retry-530 (regex)
              Retry  on server reply 530 for PASS command if text matches this
              regular  expression.   This  setting   should   be   useful   to
              distinguish  between overloaded server (temporary condition) and
              incorrect password (permanent condition).

       ftp:retry-530-anonymous (regex)
              Additional  regular  expression  for   anonymous   login,   like

       ftp:site-group (string)
              Send  this  string in SITE GROUP command after login. The result
              is ignored.  The closure for this setting has format  user@host.

       ftp:skey-allow (boolean)
              allow  sending  skey/opie reply if server appears to support it.
              On by default.

       ftp:skey-force (boolean)
              do not send plain text password over the network, use  skey/opie
              instead. If skey/opie is not available, assume failed login. Off
              by default.

       ftp:ssl-allow (boolean)
              if true, try to negotiate SSL connection  with  ftp  server  for
              non-anonymous  access.  Default  is  true.  This  and  other ssl
              settings are only available if lftp was compiled with an ssl/tls

       ftp:ssl-data-use-keys (boolean)
              if  true,  lftp loads ssl:key-file for protected data connection
              too. When false, it does not, and the server can match data  and
              control connections by session ID.  Default is true.

       ftp:ssl-force (boolean)
              if  true,  refuse to send password in clear when server does not
              support SSL.  Default is false.

       ftp:ssl-protect-data (boolean)
              if true, request ssl connection for data transfers. This is cpu-
              intensive but provides privacy. Default is false.

       ftp:ssl-protect-fxp (boolean)
              if  true,  request  ssl connection for data transfer between two
              ftp servers in FXP mode. CPSV or SSCN command will  be  used  in
              that  case.  If ssl connection fails for some reason, lftp would
              try unprotected FXP transfer unless ftp:ssl-force is set for any
              of the two servers. Default is false.

       ftp:ssl-protect-list (boolean)
              if true, request ssl connection for file list transfers. Default
              is true.

       ftp:ssl-use-ccc (boolean)
              if true, lftp would issue CCC command after logon, thus  disable
              ssl protection layer on control connection.

       ftp:stat-interval (time interval)
              interval between STAT commands. Default is 1 second.

       ftp:sync-mode (boolean)
              if  true,  lftp  will  send  one  command at a time and wait for
              response. This might be useful if you  are  using  a  buggy  ftp
              server  or router. When it is off, lftp sends a pack of commands
              and waits for responses - it speeds up operation when round trip
              time  is  significant.   Unfortunately it does not work with all
              ftp servers and some routers have troubles with it, so it is  on
              by default.

       ftp:timezone (string)
              Assume  this  timezone  for  time  in  listings returned by LIST
              command.  This setting can be GMT  offset  [+|-]HH[:MM[:SS]]  or
              any     valid     TZ     value     (e.g.     Europe/Moscow    or
              MSK-3MSD,M3.5.0,M10.5.0/3). The default is GMT.  Set  it  to  an
              empty  value  to  assume local timezone specified by environment
              variable TZ.

       ftp:trust-feat (string)
              When true, assume that FEAT returned data are correct and  don’t
              use common protocol extensions like SIZE, MDTM, REST if they are
              not listed.  Default is false.

       ftp:use-abor (boolean)
              if false, lftp does  not  send  ABOR  command  but  closes  data
              connection immediately.

       ftp:use-allo (boolean)
              when  true (default), lftp sends ALLO command before uploading a

       ftp:use-feat (boolean)
              when  true  (default),  lftp  uses  FEAT  command  to  determine
              extended features of ftp server.

       ftp:use-fxp (boolean)
              if  true,  lftp will try to set up direct connection between two
              ftp servers.

       ftp:use-hftp (boolean)
              when ftp:proxy points to an http  proxy,  this  setting  selects
              hftp  method  (GET,  HEAD)  when  true,  and CONNECT method when
              false. Default is true.

       ftp:lang (boolean)
              the  language  selected  with  LANG  command,  if  supported  as
              indicated  by FEAT response. Default is empty which means server

       ftp:use-mdtm (boolean)
              when true (default), lftp uses MDTM command  to  determine  file
              modification time.

       ftp:use-mdtm-overloaded (boolean)
              when  true,  lftp  uses  two  argument  MDTM command to set file
              modification time on uploaded files. Default is false.

       ftp:use-site-idle (boolean)
              when  true,  lftp  sends  ‘SITE  IDLE’  command  with   net:idle
              argument. Default is false.

       ftp:use-site-utime (boolean)
              when  true,  lftp  sends  5-argument ‘SITE UTIME’ command to set
              file modification time on uploaded files. Default is true.

       ftp:use-site-utime2 (boolean)
              when true, lftp sends 2-argument ‘SITE  UTIME’  command  to  set
              file  modification  time on uploaded files. Default is true.  If
              5-argument ‘SITE UTIME’ is also enabled, 2-argument  command  is
              tried first.

       ftp:use-size (boolean)
              when  true  (default),  lftp uses SIZE command to determine file

       ftp:use-stat (boolean)
              if true, lftp sends STAT command in FXP mode  transfer  to  know
              how  much data has been transferred. See also ftp:stat-interval.
              Default is true.

       ftp:use-stat-for-list (boolean)
              when true, lftp uses STAT instead of LIST  command.  By  default
              ‘.’  is  used as STAT argument. Using STAT, lftp avoids creating
              data connection for  directory  listing.  Some  servers  require
              special  options  for STAT, use ftp:list-options to specify them
              (e.g. -la).

       ftp:use-telnet-iac (boolean)
              when true (default), lftp uses TELNET IAC  command  and  follows
              TELNET  protocol as specified in RFC959. When false, it does not
              follow TELNET protocol and thus does not double 255 (0xFF, 0377)
              character and does not prefix ABOR and STAT commands with TELNET
              IP+SYNCH signal.

       ftp:use-quit (boolean)
              if true, lftp sends QUIT before disconnecting from  ftp  server.
              Default is true.

       ftp:verify-address (boolean)
              verify  that  data  connection comes from the network address of
              control  connection  peer.  This  can  possibly   prevent   data
              connection   spoofing   which   can  lead  to  data  corruption.
              Unfortunately, this  can  fail  for  certain  ftp  servers  with
              several  network  interfaces,  when  they  do  not  set outgoing
              address on data socket, so it is disabled by default.

       ftp:verify-port (boolean)
              verify that data connection has port 20 (ftp-data) on its remote
              end.   This  can  possibly  prevent  data connection spoofing by
              users of remote host. Unfortunately, too many windows  and  even
              unix  ftp  servers forget to set proper port on data connection,
              thus this check is off by default.

       ftp:web-mode (boolean)
              disconnect after closing data connection. This can be useful for
              totally broken ftp servers. Default is false.

       ftps:initial-prot (string)
              specifies  initial  PROT setting for FTPS connections. Should be
              one of: C, S, E, P, or  empty.  Default  is  empty  which  means
              unknown,  so that lftp will use PROT command unconditionally. If
              PROT command turns out to be unsupported, then Clear mode  would
              be assumed.

       hftp:cache (boolean)
              allow server/proxy side caching for ftp-over-http protocol.

       hftp:cache-control (string)
              specify corresponding HTTP request header.

       hftp:proxy (URL)
              specifies  http  proxy  for  ftp-over-http  protocol (hftp). The
              protocol hftp cannot  work  without  a  http  proxy,  obviously.
              Default value is taken from environment variable ftp_proxy if it
              starts with ‘‘http://’’,  otherwise  from  environment  variable
              http_proxy.   If your ftp proxy requires authentication, specify
              user name and password in the URL.

       hftp:use-authorization (boolean)
              if set to off, lftp will send password as part  of  URL  to  the
              proxy.  This  may  be  required  for some proxies (e.g. M-soft).
              Default  is  on,  and  lftp  will  send  password  as  part   of
              Authorization header.

       hftp:use-head (boolean)
              if  set to off, lftp will try to use ‘GET’ instead of ‘HEAD’ for
              hftp protocol.  While this is slower, it may allow lftp to  work
              with  some  proxies  which  don’t understand or mishandle ‘‘HEAD
              ftp://’’ requests.

       hftp:use-mkcol (boolean)
              if set to off, lftp will try to use ‘PUT’ instead of ‘MKCOL’  to
              create directories with hftp protocol. Default is off.

       hftp:use-propfind (boolean)
              if  set  to  off,  lftp  will  not  try to use ‘PROPFIND’ to get
              directory contents with hftp protocol  and  use  ‘GET’  instead.
              Default is off.

       hftp:use-type (boolean)
              If  set to off, lftp won’t try to append ‘;type=’ to URLs passed
              to proxy.   Some  broken  proxies  don’t  handle  it  correctly.
              Default is on.

       http:accept, http:accept-charset, http:accept-language (string)
              specify corresponding HTTP request headers.

       http:authorization (string)
              the  authorization to use by default, when no user is specified.
              The format is ‘‘user:password’’. Default is empty which means no

       http:cache (boolean)
              allow server/proxy side caching.

       http:cache-control (string)
              specify corresponding HTTP request header.

       http:cookie (string)
              send this cookie to server. A closure is useful here:
                   set cookie/ "param=value"

       http:post-content-type (string)
              specifies  value  of  Content-Type  http request header for POST
              method.  Default is ‘‘application/x-www-form-urlencoded’’.

       http:proxy (URL)
              specifies http proxy. It is  used  when  lftp  works  over  http
              protocol.   Default  value  is  taken  from environment variable
              http_proxy.  If your proxy requires authentication, specify user
              name and password in the URL.

       http:put-method (PUT or POST)
              specifies which http method to use on put.

       http:put-content-type (string)
              specifies  value  of  Content-Type  http  request header for PUT

       http:referer (string)
              specifies value for Referer http request header. Single dot  ‘.’
              expands  to  current directory URL. Default is ‘.’. Set to empty
              string to disable Referer header.

       http:set-cookies (boolean)
              if true, lftp modifies  http:cookie  variables  when  Set-Cookie
              header is received.

       http:use-mkcol (boolean)
              if  set to off, lftp will try to use ‘PUT’ instead of ‘MKCOL’ to
              create directories with http protocol. Default is on.

       http:use-propfind (boolean)
              if set to off, lftp will  not  try  to  use  ‘PROPFIND’  to  get
              directory  contents  with  http  protocol and use ‘GET’ instead.
              Default is on.

       http:user-agent (string)
              the string lftp sends in User-Agent header of HTTP request.

       https:proxy (string)
              specifies https proxy. Default value is taken  from  environment
              variable https_proxy.

       mirror:dereference (boolean)
              when  true,  mirror  will dereference symbolic links by default.
              You can override  it  by  --no-dereference  option.  Default  if

       mirror:exclude-regex (regex)
              specifies  default  exclusion  pattern.  You  can override it by
              --include option.

       mirror:include-regex (regex)
              specifies default inclusion  pattern.  It  is  used  just  after
              mirror:exclude-regex   is   applied.   It   is   never  used  if
              mirror:exclude-regex is empty.

       mirror:order (list of patterns)
              specifies order of file transfers. E.g. setting this  to  "*.sfv
              *.sum" makes mirror to transfer files matching *.sfv first, then
              ones matching  *.sum  and  then  all  other  files.  To  process
              directories  after other files, add "*/" to end of pattern list.

       mirror:parallel-directories (boolean)
              if true, mirror will start processing of several directories  in
              parallel  when  it  is  in  parallel  mode.  Otherwise,  it will
              transfer files from a single directory before  moving  to  other

       mirror:parallel-transfer-count (number)
              specifies  number  of  parallel  transfers  mirror is allowed to
              start. Default is  1.   You  can  override  it  with  --parallel

       mirror:set-permissions (boolean)
              When  set  to  off,  mirror won’t try to copy file and directory
              permissions.  You can override it by --perms option. Default  is

       mirror:use-pget-n (number)
              specifies  -n  option  for  pget  command used to transfer every
              single file under mirror. Default is 1 which disables pget.

       module:path (string)
              colon separated list of directories to look for modules. Can  be
              initialized by environment variable LFTP_MODULE_PATH. Default is

       net:connection-limit (number)
              maximum number of concurrent connections to  the  same  site.  0
              means unlimited.

       net:connection-takeover (boolean)
              if  true,  foreground  connections have priority over background
              ones and  can  interrupt  background  transfers  to  complete  a
              foreground operation.

       net:idle (time interval)
              disconnect  from  server  after  this  idle  time.  Default is 3

       net:limit-rate (bytes per second)
              limit transfer rate on data connection. 0 means  unlimited.  You
              can specify two numbers separated by colon to limit download and
              upload rate separately.

       net:limit-max (bytes)
              limit accumulating of unused limit-rate. 0 means twice of limit-

       net:limit-total-rate (bytes per second)
              limit   transfer  rate  of  all  connections  in  sum.  0  means
              unlimited. You can specify two numbers  separated  by  colon  to
              limit  download  and  upload rate separately.  Note that sockets
              have receive buffers on them, this can lead to network link load
              higher  than  this rate limit just after transfer beginning. You
              can try to set net:socket-buffer to relatively  small  value  to
              avoid this.

       net:limit-total-max (bytes)
              limit  accumulating of unused limit-total-rate. 0 means twice of

       net:max-retries (number)
              the maximum number of sequential retries of an operation without
              success.  0 means unlimited.

       net:no-proxy (string)
              contains  comma separated list of domains for which proxy should
              not  be  used.   Default  is  taken  from  environment  variable

       net:persist-retries (number)
              ignore  this number of hard errors. Useful to login to buggy ftp
              servers which reply 5xx when there is too many users.

       net:reconnect-interval-base (seconds)
              sets the base minimal time between reconnects.  Actual  interval
              depends   on  net:reconnect-interval-multiplier  and  number  of
              attempts to perform an operation.

       net:reconnect-interval-max (seconds)
              sets maximum reconnect interval.  When  current  interval  after
              multiplication  by net:reconnect-interval-multiplier reachs this
              value (or exceeds  it),  it  is  reset  back  to  net:reconnect-

       net:reconnect-interval-multiplier (real number)
              sets  multiplier  by which base interval is multiplied each time
              new attempt to perform an operation  fails.  When  the  interval
              reachs  maximum,  it  is reset to base value. See net:reconnect-
              interval-base and net:reconnect-interval-max.

       net:socket-bind-ipv4 (ipv4 address)
              bind all IPv4 sockets to specified address. This can  be  useful
              to  select a specific network interface to use. Default is empty
              which means not to bind  IPv4  sockets,  operating  system  will
              choose an address automatically using routing table.

       net:socket-bind-ipv6 (ipv6 address)
              the same for IPv6 sockets.

       net:socket-buffer (bytes)
              use  given  size  for  SO_SNDBUF and SO_RCVBUF socket options. 0
              means system default.

       net:socket-maxseg (bytes)
              use given size for TCP_MAXSEG socket option. Not  all  operating
              systems support this option, but linux does.

       net:timeout (time interval)
              sets the network protocol timeout.

       pget:default-n (number)
              default number of chunks to split the file to in pget.

       pget:save-status (time interval)
              save  pget transfer status this often. Set to ‘never’ to disable
              saving of the status file.  The status is saved to a  file  with
              suffix .lftp-pget-status.

       sftp:charset (string)
              the  character  set  used  by sftp server in file names and file
              listings.  Default is empty which means the same as local.  This
              setting  is  only  used  for  sftp  protocol version prior to 4.
              Version 4 and later always use UTF-8.

       sftp:connect-program (string)
              the program to use for connecting to remote  server.  It  should
              support ‘-l’ option for user name, ‘-p’ for port number. Default
              is ‘ssh -a -x’. You can set it to ‘rsh’, for example.

       sftp:max-packets-in-flight (number)
              The maximum number of unreplied packets in flight. If round trip
              time   is  significant,  you  should  increase  this  and  size-
              read/size-write. Default is 16.

       sftp:protocol-version (number)
              The protocol number to  negotiate.  Default  is  4.  The  actual
              protocol version used depends on server.

       sftp:server-program (string)
              The  server  program  implementing SFTP protocol. If it does not
              contain a slash ‘/’, it is considered a ssh2  subsystem  and  -s
              option  is  used  when  starting  connect-program.   Default  is
              ‘sftp’. You can use rsh as transport level protocol like this:
                   set sftp:connect-program rsh
                   set sftp:server-program /usr/libexec/openssh/sftp-server
              Similarly you can run sftp over ssh1.

       sftp:size-read (number)
              Block size for reading. Default is 0x8000.

       sftp:size-write (number)
              Block size for writing. Default is 0x8000.

       ssl:ca-file (path to file)
              use specified file as Certificate Authority certificate.

       ssl:ca-path (path to directory)
              use specified directory  as  Certificate  Authority  certificate
              repository (OpenSSL only).

       ssl:check-hostname (boolean)
              when  true,  lftp checks if the host name used to connect to the
              server corresponds to the host name in its certificate.

       ssl:crl-file (path to file)
              use specified file as Certificate Revocation List certificate.

       ssl:crl-path (path to directory)
              use  specified  directory   as   Certificate   Revocation   List
              certificate repository (OpenSSL only).

       ssl:key-file (path to file)
              use specified file as your private key.

       ssl:cert-file (path to file)
              use specified file as your certificate.

       ssl:verify-certificate (boolean)
              if  set to yes, then verify server’s certificate to be signed by
              a  known  Certificate  Authority  and  not  be  on   Certificate
              Revocation List.

       torrent:ip (ipv4 address)
              IP  address for the tracker. Specify it if you are using an http

       torrent:max-peers (number)
              maximum number of peers for a  torrent.  Least  used  peers  are
              removed to maintain this limit.

       torrent:port-range (from-to)
              port  range  to accept connections on. A single port is selected
              when a torrent starts.

       torrent:seed-max-time (time interval)
              maximum seed time. After this period of time a complete  torrent
              shuts  down independently of ratio. It can be set to infinity if

       torrent:seed-min-peers (number)
              minimum number of peers when the torrent is complete.  If  there
              are less, new peers are actively searched for.

       torrent:stop-on-ratio (real number)
              torrent  stops when it’s complete and ratio reached this number.

       xfer:clobber (boolean)
              if this setting is off, get commands will not overwrite existing
              files and generate an error instead. Default is on.

       xfer:destination-directory (path or URL to directory)
              This  setting  is  used  as  default  -O option for get and mget
              commands.  Default is empty, which means current  directory  (no
              -O option).

       xfer:full-disk-fatal (boolean)
              when true, lftp aborts a thansfer if it cannot write target file
              because of full disk or quota; when false, lftp waits  for  disk
              space to be freed.

       xfer:eta-period (seconds)
              the  period  over  which  weighted average rate is calculated to
              produce ETA.

       xfer:eta-terse (boolean)
              show terse ETA (only high order parts). Default is true.

       xfer:log (boolean)
              when true, lftp logs transfers to ~/.lftp/transfer_log.

       xfer:max-redirections (number)
              maximum  number  of  redirections.  This  can  be   useful   for
              downloading over HTTP.  0 prohibits redirections.

       xfer:rate-period (seconds)
              the  period over which weighted average rate is calculated to be

       The name of a variable can be abbreviated unless it becomes  ambiguous.
       The  prefix  before  ‘:’  can  be omitted too. You can set one variable
       several times for different closures, and thus you can get a particular
       settings  for  particular  state.  The closure is to be specified after
       variable name separated with slash ‘/’.

       The  closure  for  ‘dns:’,  ‘net:’,  ‘ftp:’,  ‘http:’,  ‘hftp:’  domain
       variables  is  currently  just  the  host name as you specify it in the
       ‘open’ command (with some exceptions where closure is meaningless, e.g.
       dns:cache-size).   For  some  ‘cmd:’  domain  variables  the closure is
       current URL without path.  For other  variables  it  is  not  currently
       used. See examples in the sample lftp.conf.

       Certain  commands  and  settings take a time interval parameter. It has
       the format Nx[Nx...], where N is time amount (floating point) and x  is
       time  unit: d - days, h - hours, m - minutes, s - seconds. Default unit
       is second. E.g. 5h30m or 5.5h.  Also the interval  can  be  ‘infinity’,
       ‘inf’,  ‘never’,  ‘forever’  -  it means infinite interval. E.g. ‘sleep
       forever’ or ‘set dns:cache-expire never’.

       Boolean settings can be one of (true, on, yes, 1, +) for a  True  value
       or one of (false, off, no, 0, -) for a False value.

       Integer  settings can have a suffix: k - kibi, m - mebi, g - gigi, etc.
       They can also have a prefix: 0 - octal, 0x - hexadecimal.

   FTP asynchronous mode (pipelining)
       Lftp can speed up ftp operations by sending several  commands  at  once
       and  then  checking  all  the  responses.  See  ftp:sync-mode variable.
       Sometimes this does not work, thus synchronous mode is the default. You
       can try to turn synchronous mode off and see if it works for you. It is
       known that some network software dealing with address translation works
       incorrectly  in the case of several FTP commands in one network packet.

       RFC959 says: ‘‘The user-process  sending  another  command  before  the
       completion  reply  would  be  in  violation of protocol; but server-FTP
       processes should queue any  commands  that  arrive  while  a  preceding
       command  is  in progress’’. Also, RFC1123 says: ‘‘Implementors MUST NOT
       assume any  correspondence  between  READ  boundaries  on  the  control
       connection  and the Telnet EOL sequences (CR LF).’’ and ‘‘a single READ
       from the control connection may include more than one FTP command’’.

       So it must be safe to send several commands at once,  which  speeds  up
       operation  a  lot  and  seems  to  work with all Unix and VMS based ftp
       servers. Unfortunately,  windows  based  servers  often  cannot  handle
       several commands in one packet, and so cannot some broken routers.


       -d     Switch on debugging mode

       -e commands
              Execute given commands and don’t exit.

       -p port
              Use the given port to connect

       -u user[,pass]
              Use the given username and password to connect

       -f script_file
              Execute commands in the file and exit

       -c commands
              Execute  the  given commands and exit. Commands can be separated
              with a semicolon, ‘&&’ or ‘||’.


       The following environment variables are processed by lftp:

       HOME   Used for (local) tilde (‘~’) expansion

       SHELL  Used by the ! command to determine the shell to run.

       PAGER  This should be the name of the pager to use.  It’s used  by  the
              more and zmore commands.

       http_proxy, https_proxy
              Used  to  set  initial  http:proxy,  hftp:proxy  and https:proxy

              Used to set initial ftp:proxy or hftp:proxy variables, depending
              on URL protocol used in this environment variable.

              Used to set initial net:no-proxy variable.

              Used to set initial module:path variable.

              Used   to   locate   the  directory  that  stores  user-specific
              configuration files.  If unset, ~/.lftp will be used.

              used to set initial color:dir-colors variable.


              system-wide   startup   file.   Actual   location   depends   on
              --sysconfdir  configure  option. It is /etc when prefix is /usr,
              /usr/local/etc by default.

       ~/.lftp/rc, ~/.lftprc
              These files are executed on lftp startup after /etc/lftp.conf.

              The  file  things  are  logged  to  when  lftp  moves  into  the
              background in nohup mode.

              The file transfers are logged to when xfer:log setting is set to

              The file is used to store lftp’s bookmarks.   See  the  bookmark

              The file is used to store last working directories for each site

              The file is consulted to get default login and password  to  ftp
              server.   Passwords  are  also searched here if an URL with user
              name but with no password is used.
