Some Useful Yum Commands

The yum utility keeps downloaded data files and packages for reuse. You may copy packages from the repository cache directories under /var/cache/yum/, and use them elsewhere if you wish. If you remove a package from the cache, you do not affect the copy of the software installed on your system.

To install the package tsclient, enter the command:
su -c 'yum install tsclient'

To install the package group MySQL Database, enter the command:
su -c 'yum groupinstall "MySQL Database"'

To remove the tsclient package from your system, use the command
su -c 'yum remove tsclient'

To remove all of the packages in the package group MySQL Database, enter the command:

su -c 'yum groupremove "MySQL Database"'
