Kill the processes and back-up accounts before removing

Remove Linux user accounts

I killed the processes and backed-up old accounts on the Peregrine UAT server 10.3.28.44. You can find tarballs for the home folders of all removed accounts on Peregrine UAT at:

10.3.28.44:/root/bak/deleted/users

To remove accounts safely I did the following:

1. Lock the account.

   # passwd -l username
   

2. Backup the home folder.

   # tar -zcvf /root/bak/deleted/users/username.$(id -u username).$(date +%Y%m%d%H%M%S).tar.gz /home/username/
   

3. Check if the user has running processes and if so kill them .

   # PROCS="$(pgrep -d, -u username 2>/dev/null)"; if [ -n "$PROCS" ]; then ps -fp $PROCS; else echo "No processes running" 1>&2; fi
   # killall -KILL -user username 
   

4. Remove the user and its home folder.

   # userdel -r username
