RPM—the Package Manager
In SUSE® Linux, RPM (RPM Package Manager) is used for managing software
packages. Its main commands are rpm and rpmbuild. The powerful RPM database
can be queried by the users, system administrators, and package builders for detailed
information about the installed software.
Essentially, rpm has five modes: installing, uninstalling, or updating software packages;
rebuilding the RPM database; querying RPM bases or individual RPM archives; integrity
checking of packages; and signing packages. rpmbuild can be used to build installable
packages from pristine sources.
Installable RPM archives are packed in a special binary format. These archives consist
of the program files to install and certain meta information used during the installation
by rpm to configure the software package or stored in the RPM database for documen-
tation purposes. RPM archives normally have the extension .rpm.
TIP: Software Development Packages
For a number of packages, the components needed for software development
(libraries, headers, include files, etc.) have been put into separate packages.
These development packages are only needed if you want to compile software
yourself, for example, the most recent GNOME packages. They can be identified
by the name extension -devel, such as the packages alsa-devel,
gimp-devel, and kdelibs3-devel.
