dpkg-depcheck - determine packages used to execute a command
This program runs the specified command under strace
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
, 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.
- -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
- -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.
Don't change locale when running command.
- -l, --list-files
Also report the list of files used in each package.
Do not report the files used in each package. Cancels a -l
- -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 if files in /usr/local or /var/local are used.
Enabled by default.
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.
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.
Warn about access to files controlled by the Debian alternatives
mechanism. Enabled by default.
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.
The two configuration files /etc/devscripts.conf
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:
These are options which are parsed before the command-line options.
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!
