RPM

In Linux, RPM Package Manager is a package management system. The name RPM variously refers to the .rpm file format, files in this format, software packaged in such files, and the package manager itself. RPM was intended primarily for GNU/Linux distributions; the file format is the baseline package format of the Linux Standard Base. Whereas an RPM typically contains the compiled version of the software, an SRPM contains either the source code corresponding to that RPM or the scripts of a non-compiled software package. Originally standing for "Red Hat Package Manager", RPM now stands for "RPM Package Manager", a recursive acronym.
