How to delete a user account on Ubuntu Linux

Here are the steps to delete a user account on Ubuntu Linux:

Log in as root or use the sudo command to run the following commands with administrative privileges:
nn
```
sudo su
```
Use the userdel command to delete the user account. Replace username with the actual username you want to delete:
nn
```
userdel username
```
By default, the user’s home directory and its contents are not deleted. To delete the home directory, use the following command:
nn
```
rm -rf /home/username
```
To remove the user’s group, use the groupdel command:
nn
```
groupdel username
```

Note: Be careful when deleting user accounts and always make sure to backup important data before making changes.
