Yellow dog Updater, Modified

From Wikipedia, the free encyclopedia

The Yellow dog Updater, Modified (YUM) is an open source command line package management utility for RPM-compatible Linux computer systems. It was developed by Seth Vidal and a group of volunteer programmers, and is currently maintained as part of Duke University's Linux@DUKE project. Though yum is a command line utility, several other tools provide graphical user interfaces to yum, among them pup, pirut, and yumex.

Yum is a full rewrite of its predecessor tool, Yellowdog Updater (YUP), and was developed primarily in order to update and manage Red Hat Linux systems used at the Duke University department of Physics. Since then, it has been adopted by Fedora Core, CentOS, and many other RPM-based Linux distributions, including Yellow Dog Linux itself, where it has replaced the original YUP utility. Red Hat's own enterprise package manager, up2date, can also make use of yum repositories when performing software updates.

Yellow dog Updater, Modified is available under the GNU GPL license version 2 or above.

[edit] Yum Repositories

Creation of yum repositories is handled by a separate tool called "createrepo", which generates the necessary XML metadata.

[edit] Plug-in/Module System

In the 2.x versions of yum, an interface for programming extensions in Python has been added which allows the behavior of yum to be altered.
