II. How to Remove (Delete) a User on Ubuntu 12.04 LTS
Pre-Flight Check
- These instructions are intended specifically for removing a user on Ubuntu 12.04 LTS.
- I’ll be working from a Liquid Web Core Managed Ubuntu 12.04 LTS server, and I’ll be logged in as root.
Step 1: Delete the User
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.
