       Lynx is a fully-featured World Wide Web (WWW) client for users  running
       cursor-addressable,   character-cell   display   devices  (e.g.,  vt100
       terminals, vt100 emulators running on Windows 95/NT or Macintoshes,  or
       any other "curses-oriented" display).  It will display hypertext markup
       language (HTML) documents containing links to  files  residing  on  the
       local  system,  as  well  as  files  residing on remote systems running
       Gopher, HTTP, FTP, WAIS, and NNTP servers.  Current  versions  of  Lynx
       run on Unix, VMS, Windows 95/NT, 386DOS and OS/2 EMX.

       Lynx  can  be  used  to access information on the World Wide Web, or to
       build information systems intended primarily  for  local  access.   For
       example,  Lynx  has  been used to build several Campus Wide Information
       Systems (CWIS).  In  addition,  Lynx  can  be  used  to  build  systems
       isolated within a single LAN.


       At  start  up, Lynx will load any local file or remote URL specified at
       the command line.  For help with URLs, press "?"  or "H" while  running
       Lynx.  Then follow the link titled, "Help on URLs."

       If  more  than  one  local  file or remote URL is listed on the command
       line, Lynx will open only the last interactively.   All  of  the  names
       (local files and remote URLs) are added to the G)oto history.

       Lynx  uses  only  long option names. Option names can begin with double
       dash as well, underscores and dashes can be intermixed in option  names
       (in  the reference below options are with one dash before them and with

       Lynx provides many command-line options.  Some options require a  value
       (string,  number  or keyword).  These are noted in the reference below.
       The other options set boolean values in the program.  There  are  three
       types of boolean options: set, unset and toggle.  If no option value is
       given, these have the obvious meaning: set (to true), unset (to false),
       or  toggle  (between  true/false).  For any of these, an explicit value
       can  be  given  in  different  forms  to  allow  for  operating  system
       constraints, e.g.,
       Lynx  recognizes  "1",  "+",  "on" and "true" for true values, and "0",
       "-", "off" and "false"  for  false  values.   Other  option-values  are

       The  default boolean, number and string option values that are compiled
       into Lynx are displayed in the help-message  provided  by  lynx  -help.
       Some  of those may differ according to how Lynx was built; see the help
       message itself for these values.  The -help option is processed in  the
       third  pass of options-processing, so any option which sets a value, as
       well as runtime configuration values are reflected in the help-message.

       -      If  the  argument  is only ’-’, then Lynx expects to receive the
              arguments from the standard input.  This is  to  allow  for  the
              potentially  very  long command line that can be associated with
              the -get_data or -post_data arguments (see below).  It can  also
              be  used  to  avoid having sensitive information in the invoking
              command line (which would be visible to other processes on  most
              systems),  especially when the -auth or -pauth options are used.

              accept all cookies.

              apply   restrictions   for   anonymous   account,    see    also

              charset for documents that don’t specify it.

              charset  assumed for local files, i.e., files which Lynx creates
              such as internal pages for the options menu.

              use this instead of unrecognized charsets.

              set authorization ID and password  for  protected  documents  at
              startup.   Be  sure  to  protect any script files which use this

       -base  prepend a request URL comment and BASE tag to text/html  outputs
              for -source dumps.

              specify a local bibp server (default http://bibhost/).

       -blink forces  high  intensity  background  colors  for  color mode, if
              available and supported by the terminal.  This  applies  to  the
              slang  library  (for  a  few terminal emulators), or to OS/2 EMX
              with ncurses.

       -book  use the bookmark page as the startfile.  The default or  command
              line  startfile  is  still  set for the Main screen command, and
              will be used if the bookmark page is unavailable or blank.

              toggles scanning of news articles  for  buried  references,  and
              converts  them  to  news  links.   Not recommended because email
              addresses enclosed in angle brackets will be converted to  false
              news links, and uuencoded messages can be trashed.

              set  the  NUMBER  of documents cached in memory.  The default is

       -case  enable case-sensitive string searching.

              Toggle center alignment in HTML TABLE.

              specifies a Lynx  configuration  file  other  than  the  default

       -child exit  on  left-arrow  in startfile, and disable save to disk and
              associated print/mail options.

              exit on left-arrow in startfile, but  allow  save  to  disk  and
              associated print/mail options.

              write   keystroke   commands  and  related  information  to  the
              specified file.

              read keystroke commands from the specified file.   You  can  use
              the  data  written  using the -cmd_log option.  Lynx will ignore
              other information which the command-logging may have written  to
              the  logfile.  Each line of the command script contains either a
              comment beginning with "#", or a keyword:

                 causes  the  script  to  stop,  and  forces  Lynx   to   exit

                 the  character  value,  in  printable form.  Cursor and other
                 special  keys  are  given  as  names,  e.g.,  "Down   Arrow".
                 Printable  7-bit ASCII codes are given as-is, and hexadecimal
                 values represent other 8-bit codes.

                 followed by a "name=value" allows one to override values  set
                 in the lynx.cfg file.

       -color forces  color  mode  on,  if  available.   Default color control
              sequences which work for many terminal types are assumed if  the
              terminal  capability  description does not specify how to handle
              color.  Lynx needs to be compiled with  the  slang  library  for
              this flag, it is equivalent to setting the COLORTERM environment
              variable.  (If color support is instead  provided  by  a  color-
              capable  curses  library like ncurses, Lynx relies completely on
              the terminal description to  determine  whether  color  mode  is
              possible,  and this flag is not needed and thus unavailable.)  A
              saved show_color=always setting  found  in  a  .lynxrc  file  at
              startup  has the same effect.  A saved show_color=never found in
              .lynxrc on startup is overridden by this flag.

              Sets the connection timeout, where N is given in seconds.

              specifies a file to use to read cookies.  If none is  specified,
              the  default  value  is  ~/.lynx_cookies  for  most systems, but
              ~/cookies for MS-DOS.

              specifies a file to use to store cookies.  If none is specified,
              the value given by -cookie_file is used.

              toggles handling of Set-Cookie headers.

       -core  toggles forced core dumps on fatal errors.  Turn this option off
              to ask Lynx to force a core dump if a fatal error occurs.

       -crawl with -traversal, output each page to a file.  with -dump, format
              output as with -traversal, but to the standard output.

              toggles   the   use  of  curses  "pad"  feature  which  supports
              left/right scrolling of the display.

              separate incremental display stages with MessageSecs delay

       -delay add DebugSecs delay after each progress-message

              set the display variable for X rexec-ed programs.

              set the charset for the terminal output.

              inhibit wrapping of text in <pre> when -dump’ing and -crawl’ing,
              mark wrapped lines in interactive session.

       -dump  dumps  the  formatted  output  of  the default document or those
              specified on  the  command  line  to  standard  output.   Unlike
              interactive mode, all documents are processed.  This can be used
              in the following way:

              lynx -dump

              enable external editing, using the specified  EDITOR.  (vi,  ed,
              emacs, etc.)

              enable emacs-like key movement.

              toggles  compatibility  with  communication programs’ scrollback
              keys (may be incompatible with some curses packages).

              define a file where Lynx will report HTTP access codes.

       -exec  enable local program execution (normally not configured).

              include all versions of files in local VMS directory listings.

              toggle memory leak-checking.  Normally this is not compiled-into
              your  executable,  but  when  it  is,  it  can be disabled for a

              force HREF-less ’A’ elements to be empty (close them as soon  as
              they are seen).

              forces the first document to be interpreted as HTML.

              toggles forcing of the secure flag for SSL cookies.

              toggles whether the Options Menu is key-based or form-based.

       -from  toggles transmissions of From headers.

       -ftp   disable ftp access.

              properly  formatted  data  for  a  get form are read in from the
              standard input and passed to the form.  Input is terminated by a
              line that starts with ’---’.

       -head  send a HEAD request for the mime headers.

       -help  print the Lynx command syntax usage message, and exit.

              control the display of hidden links.

                 hidden  links  show  up as bracketed numbers and are numbered
                 together with other links in the sequence of their occurrence
                 in the document.

                 hidden  links  are  shown  only on L)ist screens and listings
                 generated by -dump  or  from  the  P)rint  menu,  but  appear
                 separately  at  the  end of those lists.  This is the default

                 hidden links do not appear even in listings.

              toggles use of ’>’ or ’-->’ as a terminator for comments.

              set homepage separate from start page.

              toggles inclusion of links for all images.

              set the default index file to the specified URL.

       -ismap toggles inclusion of  ISMAP  links  when  client-side  MAPs  are

              do justification of text.

              starting count for lnk#.dat files produced by -crawl.

              for -dump, show only the list of links.

              disable URLs that point to remote hosts.

              enable  local  program  execution from local files only (if Lynx
              was compiled with local execution enabled).

              specify  filename  containing  color-style   information.    The
              default is lynx.lss.  If you give an empty filename, lynx uses a
              built-in monochrome scheme which  imitates  the  non-color-style

              prints  the  MIME  header  of  a fetched document along with its

              toggles minimal versus valid comment parsing.

              toggles nested-tables logic (for debugging).

              number of articles in chunked news listings.

              maximum news articles in listings before chunking.

              disable bold video-attribute.

              disable directory browsing.

       -nocc  disable Cc: prompts for self copies of mailings.  Note that this
              does  not disable any CCs which are incorporated within a mailto
              URL or form ACTION.

              force color mode off, overriding terminal capabilities  and  any
              -color flags, COLORTERM variable, and saved .lynxrc settings.

              disable -more- string in statusline messages.

              This  flag  is  not  available  on all systems, Lynx needs to be
              compiled with HAVE_SIGACTION defined.  If available,  this  flag
              may  cause Lynx to react more immediately to window changes when
              run within an xterm.

              disable   link-    and    field-numbering.     This    overrides
              -number_fields and -number_links.

              disable forced pauses for statusline messages.

              disable most print functions.

              windows or as lists of radio buttons.

              properly formatted data for a post form are  read  in  from  the
              standard input and passed to the form.  Input is terminated by a
              line that starts with ’---’.

              the portion which cannot be displayed.  The beginning and end of
              the URL are displayed, rather than suppressing the end.

              Print the configuration settings, e.g., as read from "lynx.cfg",
              and exit.

              If  enabled  the  cursor  will  not  be hidden in the right hand
              corner but will instead  be  positioned  at  the  start  of  the
              currently selected link.  Show cursor is the default for systems
              without FANCY_CURSES capabilities.   The  default  configuration
              can  be  changed  in  userdefs.h  or lynx.cfg.  The command line
              switch toggles the default.

              If enabled the transfer  rate  is  shown  in  bytes/second.   If
              disabled,  no  transfer  rate  is  shown.   Use  lynx.cfg or the
              options menu to select KB/second and/or ETA.

              toggles emulation of the  old  Netscape  and  Mosaic  bug  which
              treated ’>’ as a co-terminator for double-quotes and tags.

              works  the  same  as  dump  but  outputs  HTML source instead of
              formatted text.  For example

              lynx -source . >foo.html

              generates  HTML  source  listing  the  files  in   the   current
              directory.   Each  file  is  marked  by  an HREF relative to the
              parent directory.  Add a  trailing  slash  to  make  the  HREF’s
              relative to the current directory:

              lynx -source ./ >foo.html

              disable SIGINT cleanup handler

              allow non-http startfile and homepage with -validate.

              When  dumping  a  document using -dump or -source, Lynx normally
              does not display alert (error) messages  that  you  see  on  the
              screen  in the status line.  Use the -stderr option to tell Lynx
              to write these messages to the standard error.

       -stdin read the startfile from standard input (UNIX only).

              information for syslog call.

              log requested URLs with syslog.

              initialize parser, using Tag Soup DTD rather than SortaSGML.

              disable recognition of telnet commands.

              tell Lynx what terminal type to assume it is talking to.   (This
              may  be  useful  for  remote  execution, when, for example, Lynx
              connects to a remote TCP/IP port that starts a script  that,  in
              turn, starts another Lynx process.)

              For  win32,  sets  the network read-timeout, where N is given in

       -tlog  toggles between using a Lynx Trace  Log  and  stderr  for  trace
              output from the session.

       -tna   turns on "Textfields Need Activation" mode.

       -trace turns  on  Lynx trace mode.  Destination of trace output depends
              on -tlog.

              turn on optional traces, which may result in  very  large  trace
              files.  Logically OR the values to combine options:

              1  SGML character parsing states

              2  color-style

              4  TRST (table layout)

              8  configuration  (lynx.cfg,  .lynxrc, .lynx-keymaps, mime.types
                 and mailcap contents)

              traverse all http links derived from startfile.  When used  with
              -crawl,  each link that begins with the same string as startfile
              is output to a file, intended for indexing.  See  CRAWL.announce
              for more information.

              trim input text/textarea fields in forms.

              toggles use of underline/bold attribute for links.

              toggles use of _underline_ format in dumps.

              turn  on  mouse  support, if available.  Clicking the left mouse
              button on a link traverses it.  Clicking the right mouse  button
              pops  back.   Click  on the top line to scroll up.  Click on the
              bottom line to scroll down.  The first few positions in the  top
              and  bottom  line may invoke additional functions.  Lynx must be
              compiled with ncurses or slang  to  support  this  feature.   If
              ncurses  is  used,  clicking  the  middle mouse button pops up a
              simple menu.  Mouse clicks may only work reliably while Lynx  is
              idle waiting for input.

              set alternate Lynx User-Agent header.

              accept  only  http  URLs  (for  validation).   Complete security
              restrictions also are implemented.

              toggle [LINK], [IMAGE] and [INLINE] comments with  filenames  of
              these images.

              print version information, and exit.

              enable vi-like key movement.

              enable  Waterloo  tcp/ip packet debug (print to watt debugfile).
              This applies only  to  DOS  versions  compiled  with  WATTCP  or

              number  of columns for formatting of dumps, default is 80.  This
              is limited by the number of columns  that  Lynx  could  display,
              typically 1024 (the MAX_LINE symbol).

              emit backspaces in output if -dump’ing or -crawl’ing (like ’man’

              tells Lynx that it can ignore certain tags which have no content
              in an XHTML 1.0 document.  For example "<p/>" will be discarded.


       o  Use Up arrow and Down arrow to scroll through hypertext links.

       o  Right arrow or Return will follow a highlighted hypertext link.

       o  Left Arrow will retreat from a link.

       o  Type "H" or "?" for  online  help  and  descriptions  of  key-stroke

       o  Type  "K"  for  a  complete  list  of the current key-stroke command


       In addition to various "standard" environment variables such  as  HOME,
       PATH,  USER,  DISPLAY, TMPDIR, etc, Lynx utilizes several Lynx-specific
       environment variables, if they exist.

       Others may be created or modified by Lynx to pass data to  an  external
       program, or for other reasons.  These are listed separately below.

       See  also  the  sections  on  SIMULATED CGI SUPPORT and NATIVE LANGUAGE
       SUPPORT, below.

       Note:  Not all environment variables apply to all  types  of  platforms
       supported  by  Lynx, though most do.  Feedback on platform dependencies
       is solicited.

       Environment Variables Used By Lynx:

       COLORTERM           If set, color capability for the terminal is forced
                           on  at  startup time.  The actual value assigned to
                           the variable is ignored.   This  variable  is  only
                           meaningful  if  Lynx  was  built  using  the  slang
                           screen-handling library.

       LYNX_CFG            This variable, if set, will  override  the  default
                           location  and name of the global configuration file
                           (normally,  lynx.cfg)  that  was  defined  by   the
                           LYNX_CFG_FILE  constant  in  the  userdefs.h  file,
                           during installation.  See the userdefs.h  file  for
                           more information.

       LYNX_HELPFILE       If set, this variable overrides the compiled-in URL
                           and configuration file URL for the Lynx help  file.

       LYNX_LOCALEDIR      If  set,  this  variable  overrides the compiled-in
                           location of the  locale  directory  which  contains
                           native language (NLS) message text.

       LYNX_LSS            This  variable,  if  set, specifies the location of
                           the  default  Lynx  character  style  sheet   file.
                           [Currently  only meaningful if Lynx was built using
                           experimental color style support.]

       LYNX_SAVE_SPACE     This variable, if set, will  override  the  default
                           path prefix for files saved to disk that is defined
                           in the lynx.cfg  SAVE_SPACE:  statement.   See  the
                           lynx.cfg file for more information.

       LYNX_TEMP_SPACE     This  variable,  if  set, will override the default
                           path prefix for temporary files  that  was  defined
                           during  installation, as well as any value that may
                           be assigned to the TMPDIR variable.

       MAIL                This variable specifies the default inbox Lynx will
                           check  for new mail, if such checking is enabled in
                           the lynx.cfg file.

       NEWS_ORGANIZATION   This variable, if set, provides the string used  in
                           the  Organization:  header of USENET news postings.
                           It will override the setting  of  the  ORGANIZATION
                           environment  variable,  if  it is also set (and, on
                           UNIX, the contents of an /etc/organization file, if

       NNTPSERVER          If  set,  this  variable specifies the default NNTP
                           server that will be used for  USENET  news  reading
                           and posting with Lynx, via news: URL’s.

       ORGANIZATION        This  variable, if set, provides the string used in
                           the Organization: header of USENET  news  postings.
                           On  UNIX,  it  will  override  the  contents  of an
                           /etc/organization file, if present.

       PROTOCOL_proxy      Lynx supports the use of proxy servers that can act
                           as firewall gateways and caching servers.  They are
                           preferable  to  the  older  gateway  servers   (see
                           WWW_access_GATEWAY,  below).  Each protocol used by
                           Lynx, (http,  ftp,  gopher,  etc),  can  be  mapped
                           separately  by setting environment variables of the
                           form   PROTOCOL_proxy    (literally:    http_proxy,
                           ftp_proxy,       gopher_proxy,       etc),       to
                           "http://some.server.dom:port/".   See  Lynx   Users
                           Guide for additional details and examples.

       SSL_CERT_DIR        Set    to    the   directory   containing   trusted

       SSL_CERT_FILE       Set to the full path and filename for your file  of
                           trusted certificates.

       WWW_access_GATEWAY  Lynx  still  supports  use of gateway servers, with
                           the  servers  specified  via   "WWW_access_GATEWAY"
                           variables  (where "access" is lower case and can be
                           "http", "ftp", "gopher" or  "wais"),  however  most
                           gateway  servers have been discontinued.  Note that
                           you do not include a terminal ’/’ for gateways, but
                           do   for   proxies   specified   by  PROTOCOL_proxy
                           environment variables.  See Lynx  Users  Guide  for

       WWW_HOME            This  variable,  if  set, will override the default
                           startup  URL  specified  in   any   of   the   Lynx
                           configuration files.

       Environment Variables Set or Modified By Lynx:

       LYNX_PRINT_DATE     This  variable is set by the Lynx p(rint) function,
                           to  the  Date:  string  seen  in   the   document’s
                           "Information  about"  page  (= cmd), if any.  It is
                           created for use by an external program, as  defined
                           in  a  lynx.cfg  PRINTER: definition statement.  If
                           the field does not  exist  for  the  document,  the
                           variable is set to a null string under UNIX, or "No
                           Date" under VMS.

       LYNX_PRINT_LASTMOD  This variable is set by the Lynx p(rint)  function,
                           to  the  Last  Mod:  string  seen in the document’s
                           "Information about" page (= cmd), if  any.   It  is
                           created  for use by an external program, as defined
                           in a lynx.cfg PRINTER:  definition  statement.   If
                           the  field  does  not  exist  for the document, the
                           variable is set to a null string under UNIX, or "No
                           LastMod" under VMS.

       LYNX_PRINT_TITLE    This  variable is set by the Lynx p(rint) function,
                           to the Linkname:  string  seen  in  the  document’s
                           "Information  about"  page  (= cmd), if any.  It is
                           created for use by an external program, as  defined
                           in  a  lynx.cfg  PRINTER: definition statement.  If
                           the field does not  exist  for  the  document,  the
                           variable is set to a null string under UNIX, or "No
                           Title" under VMS.

       LYNX_PRINT_URL      This variable is set by the Lynx p(rint)  function,
                           to   the   URL:   string  seen  in  the  document’s
                           "Information about" page (= cmd), if  any.   It  is
                           created  for use by an external program, as defined
                           in a lynx.cfg PRINTER:  definition  statement.   If
                           the  field  does  not  exist  for the document, the
                           variable is set to a null string under UNIX, or "No
                           URL" under VMS.

       LYNX_TRACE          If set, causes Lynx to write a trace file as if the
                           -trace option were supplied.

       LYNX_TRACE_FILE     If set, overrides the compiled-in name of the trace
                           file,  which  is  either Lynx.trace or LY-TRACE.LOG
                           (the latter on the DOS platform).  The  trace  file
                           is in either case relative to the home directory.

       LYNX_VERSION        This  variable  is  always  set by Lynx, and may be
                           used by an external program to determine if it  was
                           invoked  by  Lynx.   See  also  the comments in the
                           distribution’s sample mailcap file,  for  notes  on
                           usage in such a file.

       TERM                Normally,   this   variable  is  used  by  Lynx  to
                           determine the terminal type being  used  to  invoke
                           Lynx.  If, however, it is unset at startup time (or
                           has the value "unknown"), or if the -term  command-
                           line  option  is  used (see OPTIONS section above),
                           Lynx will set or  modify  its  value  to  the  user
                           specified  terminal  type  (for  the Lynx execution
                           environment).  Note: If set/modified by  Lynx,  the
                           values  of  the  LINES  and/or  COLUMNS environment
                           variables may also be changed.


       If built with the cgi-links option enabled, Lynx allows access to a cgi
       script directly without the need for an http daemon.

       When  executing  such  "lynxcgi  scripts"  (if  enabled), the following
       variables may be set for simulating a CGI environment:














       Other environment variables are not inherited  by  the  script,  unless
       they   are   provided   via  a  LYNXCGI_ENVIRONMENT  statement  in  the
       configuration file.  See the lynx.cfg file, and  the  (draft)  CGI  1.1
       Specification <http://Web.Golux.Com/coar/cgi/draft-coar-cgi-v11-00.txt>
       for the definition and usage of these variables.

       The CGI Specification, and other associated  documentation,  should  be
       consulted for general information on CGI script programming.


       If  configured  and  installed  with Native Language Support, Lynx will
       display status and other messages in your local language.  See the file
       ABOUT_NLS  in  the  source distribution, or at your local GNU site, for
       more information about internationalization.

       The following environment  variables  may  be  used  to  alter  default

       LANG                This  variable,  if  set, will override the default
                           message language.  It is an ISO 639 two-letter code
                           identifying  the  language.  Language codes are NOT
                           the same as the country codes given in ISO 3166.

       LANGUAGE            This variable, if set, will  override  the  default
                           message language.  This is a GNU extension that has
                           higher priority for  setting  the  message  catalog
                           than LANG or LC_ALL.

       LC_ALL              and

       LC_MESSAGES         These  variables,  if  set,  specify  the notion of
                           native language formatting style.  They are POSIXly

       LINGUAS             This  variable,  if  set  prior  to  configuration,
                           limits the installed languages to specific  values.
                           It  is  a space-separated list of two-letter codes.
                           Currently, it is hard-coded to a wish list.

       NLSPATH             This variable, if set, is used as the  path  prefix
                           for message catalogs.

       Note  that  man  page  availability  and  section numbering is somewhat
       platform dependent, and may vary from the above references.

       A section shown as (GNU), is intended to denote that the topic  may  be
       available  via  an  info  page,  instead of a man page (i.e., try "info
       subject", rather than "man subject").

       A section shown as (?) denotes that documentation on the topic  exists,
       but  is  not part of an established documentation retrieval system (see
       the distribution files associated  with  the  topic,  or  contact  your
       System Administrator for further information).


       Lynx  has  incorporated  code  from a variety of sources along the way.
       The earliest  versions  of  Lynx  included  code  from  Earl  Fogel  of
       Computing  Services  at the University of Saskatchewan, who implemented
       HYPERREZ in the Unix  environment.   HYPERREZ  was  developed  by  Niel
       Larson  of and served as the model for the early versions of
       Lynx.  Those versions also incorporated libraries from the Unix  Gopher
       clients  developed  at  the  University  of  Minnesota,  and  the later
       versions of Lynx rely on the WWW client library code developed  by  Tim
       Berners-Lee  and  the  WWW  community.  Also a special thanks to Foteos
       Macrides who ported much of Lynx to VMS and did or  organized  most  of
       its development since the departures of Lou Montulli and Garrett Blythe
       from the University of Kansas in the summer of 1994 through the release
       of  v2.7.2,  and  to  everyone on the net who has contributed to Lynx’s
       development either directly (through patches, comments or bug  reports)
       or indirectly (through inspiration and development of other systems).
