One Day One GNU/Linux Command
=============================
apt-cache -- Debian APT (Advanced Package Tool) package handling
utility.
Summary:
apt-cache performs a variety of operations on APT's package cache.
apt-cache does not manipulate the state of the system, but does
provide operations to search and generate interesting output from
the package meta-data (/var/lib/apt/lists).
Examples:
$ apt-cache search xfree86 -- Show package info and descriptions for
the search-string (xfree86).
$ apt-cache policy gcc -- Show version and priorities of the available
Packages.
$ apt-cache show postgresql -- Show detailed description of postgresql
package.
$ apt-cache showpkg mozilla -- Show all kind of dependencies for the
Mozilla package.
$ apt-cache depends mozilla -- List the packages needed by Mozilla.
$ apt-cache rdepends kde -- List all packages that needs KDE.
