YUM (Yellowdog Updater Modified)

yum install package_name

A command used to install a specified software package on Red Hat-based systems.

yum remove package_name

A command used to remove a specified software package on Red Hat-based systems.

rpm -qa | grep telnet

A command to query all installed RPM packages and filter for those containing 'telnet'.

yum list

A command to list all available and installed packages on Red Hat-based systems.

yum list | grep telnet*
