Ubuntu Manpage: dpkg-depcheck - determine packages used to execute a command

Provided by: devscripts_2.20.2ubuntu2_amd64

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!
