RPM Package Manager

RPM Package Manager (or RPM, originally called Red Hat Package Manager, but became a recursive acronym) is a package management tool intended for GNU/Linux. It is able to install, update, uninstall, verify and request programs. RPM is the starting package format of the Linux Standard Base.

Originally developed by Red Hat for Red Hat Linux, today many GNU/Linux distributions use it, among which the most prominent are Fedora, Mageia, PCLinuxOS, openSUSE, SuSE Linux. It has also been ported to other operating systems.

Features

For the system administrator who maintains and updates software, using a package manager instead of building them manually has advantages such as simplicity, consistency, and the ability to automate those processes.

Among the features of RPM are:

• Packages can be encrypted and verified with GPG and MD5.
• Source code files (e.g. .tar.gz, .tar.bz2) are included in SRPMs, enabling further verification.
• PatchRPMs and DeltaRPMs, which are equivalent to patch files, can incrementally update the installed RPM packages.
• The units can be automatically resolved by the package manager.

Some Commands:

rpm -qa = show installed packages.

rpm -qi foo = display the information of an RPM package.

rpm -ql foo = list files from an installed RPM package.

rpm -qc foo = list only configuration files.

rpm --checksig foo = check signature of an RPM package.

rpm -ivh n#34;local File.rpm#34; = install a package.

rpm -e "localFile.rpm" = uninstalls a package.
