Kill all processes for a given user

Question

Is there a reliable way to kill all the processes of a given user? kill(-1, SIGKILL) as that user will work, unless a rogue process of that user kills the killi

Answer 1

Here is a one liner that does this, just replace username with the username you want to kill things for. Don't even think on putting root there!

pkill -9 -u `id -u username`

Note: if you want to be nice remove -9, but it will not kill all kinds of processes.
