This is the original way of installing software in Linux / Unix.

This is a newer and more preferred method of installing software by command-line on a Redhat / Centos / Fedora Linux distribution. The yum utility is a program which is a <u>'''wrapper'''</u> for the rpm command. A wrapper program simply means a program that uses another utility (in this case, the rpm command). We have used the rpm command to query or determine information regarding installed applications on our Linux systems. When your Linux operating systems were installed, the installation DVD or network media contained rpm files that were installed on the system. Rpm files are simply pre-compiled programs that make it easier to install applications for a Linux system.

# To install applications contained on local media (eg. installation DVD), issue the command: '''yum localinstall [ full_pathname_to_xchat_rpm_file ]'''

# To provide information regarding installed application, issue the command: '''yum info packagename''' or '''rpm -qi packagename'''
