yum

Package management utility for RHEL, Feodra, and CentOS (for older versions).

• Synchronize list of packages and versions available. This should be run first, before running subsequent yum commands:

yum update

• Install a new package:

yum install {{package}}

• Install a new package and assume yes to all questions (also works with update, great for automated updates):

yum -y install {{package}}

• Find the package that provides a particular command:

yum provides {{command}}

• Remove a package:

yum remove {{package}}

• Upgrade installed packages to newest available versions:

yum upgrade
