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

Provided by: devscripts_2.16.2ubuntu3_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!
