rpm -- RedHat Package Manager
Summary:
RPM is a RedHat Package Manager, which can be used to build, install,
query, verify, update, and erase individual software packages.
A package consists of an archive of files and meta-data used to
install and erase the archive files. The meta-data includes helper
scripts, file attributes, and descriptive information about the
package.
Packages come in two varieties: binary packages, used to encapsulate
software to be installed, and source packages, containing the source
code and 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.
$ rpm -q gcc --qf "%-30{NAME} %10{SIZE} %{DISTRIBUTION}\n" -- Show
selected info tags of the package installed gcc.
$ rpm --querytags -- Show all supported TAGs.
$ rpm -ivh new.rpm -- Install the new RPM. (v - Verbose, h- Show
Progress bar).
$ rpm -U latest.rpm -- Update an Installed RPM.
$ rpm -F latest.rpm -- Freshen (Update only if installed).
$ rpm -e Package-Name -- Remove a package.
