## 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
              processed.   You  are  advised  not  to try tricky quoting, because of the vagaries of
              shell quoting!
