Finding out software packages for installation1. Check whether the software is currently installed with in the system.

2. Check whether the software package is available in the CentOS DVD.

3. Check whether the software package is available in the CentOS on-linerepositories (Free Software Server)

4. If the software is commercial check the original software developers website. Otherwise if the software is a free software use a RPM search engineto locate it.

To manage software within the Linux system we have to always use thesoftware manager program that comes with the YUM (Yellowdog Updater,Modified).
