Yum Update

YUM is a program that aids with managing RPM packages and thus managing software installs and updates on Redhat type Linux Distributions.

This information is for people who maintain a personal Linux computer --- updates on HEP Linux cluster computers are handled by the admin.

YUM Commands

Tell YUM to install a new package (one that isn't on the system at all):

yum install firefox

Tell YUM to remove a package:

yum remove mozilla

Tell YUM to update the system (checks for updates of all installed packages):

yum update

ask yum about what is installed on the system:

yum list

ask yum about a specfic package (will list available and installed packages):

yum list kernel*

Note the * wildcard above, this will list packages with names beginning with kernel, such as kernel-utils, etc.
