It’s just one simple command to add a user. In this case, we’re adding a user called mynewuser:
userdel mynewuser
If you want to remove all of the files for the user, then use -r:
userdel -r mynewuser
Step 2: Remove Root Privileges to the User
visudo
Find the following code:
## Allow root to run any commands anywhere
root ALL=(ALL:ALL) ALL
mynewuser ALL=(ALL:ALL) ALL
In this case, we’re removing root privileges from the user mynewuser. Remove the following:
mynewuser ALL=(ALL:ALL) ALL
Then exit and save the file with the key commands Ctrl-x, Y, enter.
