List installed packages with YUM

Posted December 2nd, 2008 in Linux/Unix/BSD (Updated June 26th, 2009)

This post looks at how to list the installed packages with YUM from the command line for YUM based Linux distributions, such as CentOS and Fedora.

It's very simple:

yum list installed

This will result in a list of all installed packages in case-sensitive alphabetical order, like in the following example:

Loading "fastestmirror" plugin
Loading "installonlyn" plugin

The list is going to be pretty long, so you might want to pipe it through "more" or "less" so you can scroll through it a page at a time:

yum list installed | more
yum list installed | less

or direct it out to a file for viewing in a text editor:

yum list installed > /tmp/yum-list.txt
