apt-rdepends - performs recursive dependency listings similar to
apt-rdepends [options] [pkgs ...]
apt-rdepends searches through the APT cache to find package dependen-
cies. 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 dependecies.
Show build dependencies instead of normal package dependencies.
dotty takes a list of packages on the command line and gener-
ates output suitable for use by springgraph. 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
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.
Shows the state of each dependency after each package version.
See --state-follow and --state-show for why this is useful.
Shows the listings of each package that depends on a package.
Furthermore, it will look at these dependent packages, and find
A comma-separated list of DEPENDS types to follow recursively.
By default, it only follows the Depends type.
The possible values for DEPENDS are: Depends, PreDepends, Sug-
gests, Recommends, Conflicts, Replaces, and Obsoletes.
In --build-depends mode, the possible values are: Build-
Depends, Build-Depends-Indep, Build-Conflicts, Build-Conflicts-
A comma-separated list of DEPENDS types to show, when display-
ing a listing. By default, it only shows the Depends type.
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, HalfConfig-
ured, 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 sys-
pkgs The list of packages on which to discover dependencies.
apt.conf(5), sources.list(5), apt-cache(8), AptPkg(3)
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
apt-rdepends cannot do reverse build-dependencies. This is really dif-
ficult, 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-
