Package removal on YUM based system
Removing package using yum
On YUM based system like Red Hat or CentOS, the package can be removed by supplying erase or remove argument to yum command along with package name. For example to remove telnet, we will use yum remove telnet
# yum remove telnet
Loaded plugins: amazon-id, rhui-lb, search-disabled-repos

The above output will be the same even if you use yum erase telnet command. Before removing it will print package details to be removed on screen and ask for confirmation to avoid unwanted removals.
Removing package using rpm command
Same task can be achieved by using rpm command with erase -e option.
# rpm -evh telnet
Preparing... ################################# [100%]
Cleaning up / removing...
1:telnet-1:0.17-60.el7 ################################# [100%]
In above example we used -e (erase), -v (verbose) and -h (print hash marks) along with name of package.
Package removal on APT based system
Removing package using apt-get
On APT based systems like Ubuntu or Debian, the package can be removed with apt-get remove <package_name> command. Note that like YUM this command doesn’t support erase option.
# apt-get remove telnet
