## 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** **de**‐‐
       **bian/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.  Us‐
              ing **-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=
              Output the package diagnostics to _FILE_ instead of stdout.

### -O --strace-output=
              Write  the  **strace**  output  to  _FILE_ when tracing _command_ instead of using a temporary
              file.

### -I --strace-input=
              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=
              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 cata‐
                     logs  at startup.  Files matching the regexp /usr/share/sgml/.*\.cat are recog‐
                     nised  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  pro‐
              cessed.   You  are advised not to try tricky quoting, because of the vagaries of shell
              quoting!
