Rename an existing user

Utilities useradd and userdel make it easy to create a new user or to delete an existing user. But renaming users on Linux is tricky. To rename any user use following steps:

usermod -l <new-name> <old-name>
usermod -d /home/<new-name> -m <new-name>
groupmod -n <new-name> <old-name>
