       dpkg-depcheck - determine packages used to execute a command


       dpkg-depcheck [options] command


       This   program  runs  the  specified  command  under  strace  and  then
       determines and outputs the packages used in the process.  The list  can
       be  trimmed  in various ways as described in the options below.  A good
       example  of  this  program  would  be  the  command  dpkg-depcheck   -b
       debian/rules  build, which would give a good first approximation to the
       Build-Depends line needed by a Debian  package.   Note,  however,  that
       this  does  not  give  any  direct  information on versions required or
       architecture-specific packages.


       -a, --all
              Report all packages used to run command.  This  is  the  default
              behaviour.   If  used  in  conjunction  with -b, -d or -m, gives
              additional  information  on  those  packages  skipped  by  these

       -b, --build-depends
              Do not report any build-essential or essential packages used, or
              any of their (direct or indirect) dependencies.

       -d, --ignore-dev-deps
              Do not show packages used which are direct dependencies of  -dev
              packages used.  This implies -b.

       -m, --min-deps
              Output  a  minimal  set  of packages needed, taking into account
              direct dependencies.  Using -m implies -d and also -b.

       -C, --C-locale
              Run command with the C locale.

              Don't change locale when running command.

       -l, --list-files
              Also report the list of files used in each package.

              Do not report the files used in  each  package.   Cancels  a  -l

       -o, --output=FILE
              Output the package diagnostics to FILE instead of stdout.

       -O, --strace-output=FILE
              Write  the strace output to FILE when tracing command instead of
              using a temporary file.

       -I, --strace-input=FILE
              Get strace output from FILE instead of tracing  command;  strace
              must have be run with the -f -q options for this to work.

       -f, --features=LIST
              Enable or disabled features given in the comma-separated LIST as
              follows.  A feature is enabled with +feature or just feature and
              disabled with -feature.  The currently recognised features are:
                     Warn  if  files  in  /usr/local  or  /var/local are used.
                     Enabled by default.
                     Discards execve when only a --version argument  is  given
                     to  the program; this works around some configure scripts
                     that check for binaries they don't actually use.  Enabled
                     by default.
                     Also   try  to  identify  files  which  are  accessed  in
                     /usr/local and /var/local.  Not usually very  useful,  as
                     Debian   does  not  place  files  in  these  directories.
                     Disabled by default.
                     Warn about access  to  files  controlled  by  the  Debian
                     alternatives mechanism.  Enabled by default.
                     Discards  access  to  SGML catalogs; some SGML tools read
                     all the registered catalogs at startup.   Files  matching
                     the  regexp  /usr/share/sgml/.*\.cat  are  recognised  as
                     catalogs.  Enabled by default.

       --no-conf, --noconf
              Do not read any configuration files.  This can only be  used  as
              the first option given on the command-line.

       -h, --help
              Display usage information and exit.

       -v, --version
              Display version and copyright information and exit.


       The  two configuration files /etc/devscripts.conf and ~/.devscripts are
       sourced in that order to set  configuration  variables.   Command  line
       options   can   be   used  to  override  configuration  file  settings.
       Environment variable  settings  are  ignored  for  this  purpose.   The
       currently recognised variable is:

              These  are  options  which  are  parsed  before the command-line
              options.  For example,

              DPKG_DEPCHECK_OPTIONS="-b -f-catch-alternatives"

              which passes these options to dpkg-depcheck before any  command-
              line  options  are processed.  You are advised not to try tricky
              quoting, because of the vagaries of shell quoting!


       dpkg(1), strace(1), update-alternatives(8) and devscripts.conf(5).
