rpm : The Red Hat Package Manager tool

Summary:

RPM is a Package Manager, which can be used to build, install, query,
verify, update, & erase individual software packages.


A package consists of an archive of files and meta-data used to
install & erase the archive files. The meta-data includes helper
scripts, file attributes, & descriptive information about the package.

Packages come in two varieties: binary packages, used to encapsulate
software to be installed, & source packages, containing the source
code & recipe necessary to produce binary packages.

Examples:

$ rpm -qa -- List all installed RPMs.

$ rpm -qf /usr/bin/gcc -- Show which package installed this file.

$ rpm -qi -filesbypkg gcc-3.2.2-5 -- Show the information and list of
files from this package

$ rpm -qR gcc-3.2.2-5 -- Show the dependency of this package.
