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.  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.

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.
