ps -ef | grep sh

This will show you which shells are running ( a few other things as well )

Send kill messages to the pid # for users running "shells".

fred 12630 12629 0 Mar 9 ttyq3 0:00 -sh

For instance, here you would do:

kill 12630

to kill Fred's shell.

Best regards,

Hi Peter,

You can use the whodo command.
This also will provide you with pids to kill the user sessions, however a shutdown will do the kills on active user sessions for you.

who -u
This will show you who is logged in, the PID of their login shell, and where they logged in from.

you can use the following command to kill the login shells for user you want to remove. Replace with the actual user name.

kill `who -u | grep | awk '{print $7}' | xargs`

If there are multiple users you can as well give

kill `who -u | grep -e -e | awk '{print $7}' | xargs`
