NAME

qdepends - show dependency info

SYNOPSIS

qdepends [opts] <pkgname>

DESCRIPTION

The qdepends applet has a couple different modes. Normally it is geared towards answering the queries "what does package X depend on" and "what packages depend on X". Both can further be classified into build, run, and post dependencies.

By default, it will tell you the build time dependencies only (DEPEND).

Currently, qdepends will only query installed packages. There is no support for querying packages not yet installed (the equery(1) tool can do that).

If there is no answer to your query (i.e. you've asked for a package that is not installed, or a version that does not match), then you will get back no output.

OPTIONS

-d, --depend: Show DEPEND info (default)
-r, --rdepend: Show RDEPEND info
-p, --pdepend: Show PDEPEND info
-k <arg>, --key <arg>: User defined vdb key
-Q <arg>, --query <arg>: Query reverse deps
-N, --name-only: Only show package name
-a, --all: Show all DEPEND info
-f, --format: Pretty format specified depend strings
--root <arg>: Set the ROOT env var
-v, --verbose: Make a lot of noise
-q, --quiet: Tighter output; suppress warnings
-C, --nocolor: Don't output color
-h, --help: Print this help and exit
-V, --version: Print version and exit

EXAMPLES

For finding out what a particular package depends on for building, you could do:

        $ qdepends nano
        app-editors/nano-2.3.2: >=sys-libs/ncurses-5.9-r1[unicode] sys-apps/file ...

This tells us that we have app-editors/nano-2.3.2 installed and it depends on ncurses (among other things).
