NAME

apt-rdepends - performs recursive dependency listings similar to apt-cache

SYNOPSIS

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.

Blue lines are pre-depends, green lines are conflicts, yellow lines are suggests, orange lines are recommends, red lines are replaces, and black lines are depends.

Caution, dotty cannot graph larger sets of packages.

-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.

The possible values for DEPENDS are: Depends , PreDepends , Suggests , Recommends , Conflicts , Replaces , and Obsoletes .

In --build-depends mode, the possible values are: Build-Depends , Build-Depends-Indep , Build-Conflicts , Build-Conflicts-Indep .

-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 .

These options are useful, if you only want to only look at the dependencies between the Installed packages on your system. You can then call:

apt-rdepends --state-follow=Installed libfoo

Or if you want to only show the packages installed on your system:

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.

Blue lines are pre-depends, green lines are conflicts, yellow lines are suggests, orange lines are recommends, red lines are replaces, and black lines are depends.

-o , --option= OPTION

Set an APT Configuration Option; This will set an arbitrary configuration option. The syntax is -o Foo::Bar=bar .

BUGS

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.
