NAME deborphan - Orphaned package finder
SYNOPSIS deborphan [OPTION]... [PACKAGE]...
DESCRIPTION deborphan finds packages that have no packages depending on them. The default operation is to search only within the libs and oldlibs sections to hunt down unused libraries. If it is invoked with an optional list of packages, only the dependencies on those pack‐ ages will be checked. The results are printed to stdout as if the option --show-deps had been given. Searching for specific packages will show the package, regardless of its pri‐ ority. It is possible to specify -, to read a list of packages from standard input.
OPTIONS -f, --status-file=FILE Use FILE as the status file. -h, --help Display a short help message and exit. -v, --version Display version information and exit. OUTPUT MODIFIERS -d, --show-deps Show a list of all installed packages and name the packages that depend on them. -P, --show-priority Show the priority of the packages found. -s, --show-section Show the sections the packages are in. --no-show-section Override showing sections when the default is to show them (see --all-packages). -z, --show-size Show the installed size of the packages found. SEARCH MODIFIERS -a, --all-packages Check all the packages, instead of only those in the libs section. Best used (if at all used) in combination with --priority. This option implies --show-section. -e, --exclude=LIST Excludes the packages named in LIST (a comma separated list) from the evaluation as if they didn't exist in the status file. -H, --force-hold Ignore "hold" dpkg-flags on packages and thus display these packages. Without this option packages with the "hold" flag set will not be displayed. Please refer to dpkg(1) for more information about package flags. Due a bug in aptitude (Debian bug #137771) hold flags created by aptitude are ignored by deborphan. --ignore-suggests --ignore-recommends Do not check if there is a package `suggesting' (--ignore-suggests) or `recommend‐ ing' (--ignore-recommends) the package. When both options are used together, debor‐ phan behaves as if the `nice-mode' mentioned below has been turned off. -n, --nice-mode Turn off nice-mode. Nice-mode checks if there is a package `suggesting' or `recom‐ mending' the package. If one is found, the package will be marked as in use, or, when --show-deps is used, print out the package suggesting the package as if it were depending on it. -p, --priority=PRIORITY Show only those packages with a priority equal to, or greater than PRIORITY. PRIOR‐ ITY may be in the range of 1-5, or one of required, important, standard, optional, extra. Default value for PRIORITY is 2 (important). --find-config This option searches for uninstalled packages which still have configuration files on the system. It implies the -a option. --libdevel Search in section libdevel in addition to libs and oldlibs. KEEP FILE MANAGEMENT -A, --add-keep PKG1...PKGn Add packages to the list of packages which are never to be reported, regardless of their state. You may specify '-' to use standard input. Note that package names are case-sensitive. -k, --keep-file=FILE Use FILE to store the list of kept-back packages. -L, --list-keep Show the list of packages that are being kept back. -R, --del-keep PKG1...PKGn Remove packages from the list of packages which are never to be reported. You may specify '-' to use standard input. If there are no dependencies for this package next time deborphan is invoked, it will be reported again. -Z, --zero-keep Purge the entire list of packages that are being kept back. The only option possi‐ ble in combination with this option is -A. GUESSING --guess-* --no-guess-* deborphan can try to guess what packages may not be of much use to you by examining the package's name and/or description. It will pretend the package is in the main/libs section, and report it as if it were a library. This method is in no way perfect or even reliable, so beware when using this! It is also possible to tell deborphan e.g. to guess all interpreters but not Perl by using --guess-interpreters --no-guess-perl or to guess all but not Mono by using --guess-all --no-guess-mono. Please note that the --no-guess- option must occur after the --guess- option it modifies, this makes it possible to declare more complex things like to guess all, except interpreters but additionally try to guess perl. The following options are to be prefixed by --guess- or (except only) by --no-guess-: common This option tries to find common packages, i.e. packages with names ending in -com‐ mon. data This option tries to find data packages, i.e. packages with names ending in -data. debug This option tries to find debugging libraries, i.e. packages with names ending in -dbg. dev This option tries to find development packages, i.e. packages with names ending in -dev. Also see option --libdevel. doc This option tries to find documentation packages, i.e. packages with names ending in -doc. dummy This option tries to find dummy packages, i.e. packages with dummy or transitional in their short description. kernel This option tries to find kernel-modules. It tries to match (-modules|^nvidia-ker‐ nel)-.*[0-9]+\.[0-9]+\.[0-9]+. interpreters Try to find all interpreter modules (i.e. imply ruby, pike, python, perl and mono). mono This option tries to find mono libraries. It tries to match ^libmono. perl This option tries to find perl modules. It tries to match ^lib.*-perl$. pike This option tries to find pike modules. It tries to match ^pike[[:digit:]]*-. python This option tries to find python modules. It tries to match ^python[[:digit:]]*-. ruby This option tries to find ruby modules. It tries to match ^lib.*-ruby[[:digit:].]*$. section This option tries to find libraries that were accidentally placed in the wrong sec‐ tion. It tries to match ^lib, but not if it ends in one of: -dbg, -doc, -perl, or -dev. all Try all of the above. only Ignore the package's section completely, and just go for the name and/or descrip‐ tion. This option must be used in conjunction with one or more of the --guess options listed above, or deborphan will not display anything.
FILES /var/lib/dpkg/status Statuses of available packages. See the section INFORMATION ABOUT PACKAGES in dpkg's man-page for more information. /var/lib/deborphan/keep A newline-separated list of packages to keep. Package names are in no particular order.
