List installed packages with YUM

Posted in Linux/Unix/BSD -

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

zlib-devel.x86_64                        1.2.3-3                installed

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

If you need to see all packages, installed and available, you can use:

yum list all

Or maybe just available packages:

yum list available
