dpkg-depcheck(1)

NAME

   dpkg-depcheck - determine packages used to execute a command

SYNOPSIS

   dpkg-depcheck [options] command

DESCRIPTION

   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.

OPTIONS

   -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
          options.

   -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.

   --no-C-locale
          Don't change locale when running command.

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

   --no-list-files
          Do not report the files used in  each  package.   Cancels  a  -l
          option.

   -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-local
                 Warn  if  files  in  /usr/local  or  /var/local are used.
                 Enabled by default.
          discard-check-version
                 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.
          trace-local
                 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.
          catch-alternatives
                 Warn about access  to  files  controlled  by  the  Debian
                 alternatives mechanism.  Enabled by default.
          discard-sgml-catalogs
                 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.

CONFIGURATION VARIABLES

   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:

   DPKG_DEPCHECK_OPTIONS
          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!
