Step 1: Remove the User Insert the username you want to delete by placing it after the userdel command. In our example, I’ll be deleting our user, Tom. userdel tom Simultaneous you can delete the user and the files owned by this user with the -r flag.  Be careful these files are not needed to run any application within your server. userdel -r tom If the above code produces the message below, don’t be alarmed, it is not an error, but rather /home/tom existed but /var/mail/tom did not. userdel: tom mail spool (/var/mail/tom) not found   Step 2: Remove Root Privileges By removing Tom’s username from our Linux system we are halfway complete, but we still need to remove their root privileges. visudo Navigate to the following section: ## Allow root to run any commands anywhere root ALL=(ALL:ALL) ALL tom ALL=(ALL:ALL) ALL Or: ## User privilege specification root ALL=(ALL:ALL) ALL tom ALL=(ALL:ALL) ALL With either result, remove access for your user by deleting the corresponding entry: tom ALL=(ALL:ALL) ALL Save and exit this file by typing :wq and press the enter key.
