NAME¶
apt-rdepends - performs recursive dependency listings similar to apt-cacheSYNOPSIS¶
apt-rdepends [options] [ pkgs ...]DESCRIPTION¶
apt-rdepends searches through the APT cache to find package dependencies. apt-rdepends knows how to emulate the result of calling apt-cache with both depends and dotty options. By default, apt-rdepends shows a listing of each dependency a package has. It will also look at each of these fulfilling packages, and recursively lists their dependencies.OPTIONS¶
- -b, --build-depends
- Show build dependencies instead of normal package dependencies.
- -d, --dotty
- dotty takes a list of packages on the command line and
generates output suitable for use by springgraph (1). The result will be a
set of nodes and edges representing the relationships between the
packages. By default the given packages will trace out all dependent
packages which can produce a very large graph.
- -p, --print-state
- Shows the state of each dependency after each package version. See --state-follow and --state-show for why this is useful.
- -r, --reverse
- Shows the listings of each package that depends on a package. Furthermore, it will look at these dependent packages, and find their dependers.
- -f, --follow=DEPENDS
- A comma-separated list of DEPENDS types to follow
recursively. By default, it only follows the Depends and
PreDepends types.
- -s, --show=DEPENDS
- A comma-separated list of DEPENDS types to show, when displaying a listing. By default, it only shows the Depends and PreDepends types.
- --state-follow=STATES
- --state-show=STATES
- These two options are similar to --follow and
--show. They both deal with the current state of a package. By
default, the value of STATES is Unknown,
NotInstalled, UnPacked, HalfConfigured,
HalfInstalled, ConfigFiles, and Installed.
apt-rdepends --state-follow=Installed
libfoo
apt-rdepends --state-follow=Installed
--state-show=Installed libfoo
- pkgs
- The list of packages on which to discover dependencies.
- -v, --vcg, --xvcg
- This option takes a list of packages on the command line
and generates output suitable for use by xvcg. The result will be a set of
nodes and edges representing the relationships between the packages. By
default the given packages will trace out all dependent packages which can
produce a very large graph.
- -o, --option=OPTION
- Set an APT Configuration Option; This will set an arbitrary configuration option. The syntax is -o Foo::Bar=bar.

apt-rdepends does not emulate apt-cache perfectly. It does not display information about virtual packages, nor does it know about virtual packages when it is in reverse dependency mode. apt-rdepends also does not know how to stop after a certain depth has been reached. apt-rdepends cannot do reverse build-dependencies. This is really difficult, since it would have to load the whole cache into memory before discovering which packages depend on others to build. apt-rdepends exists. This functionality should really reside in apt-cache itself.AUTHOR¶
