test pts/td 1:44pm more -s
---------------

Hi:

The 'ppid' of a process is its parent pid.

If you wanted to find all processes belonging to a user (e.g. "unixguy") you can do:

# UNIX95= ps -u unixguy -o pid,ppid,comm

Notice that there is a space without any semicolon after "UNIX95=" before the 'ps' command. This sets the XPG4 (or 'UNIX95') behavior only for the duration of the command line since setting it can have side-effects for other commands that you may not want or know.

Now if you wanted to kill all of these do:

PIDS=$(UNIX95= ps -u unixguy -opid=)
for HOW in 1 15 9
do
kill -${HOW}
sleep 2
done

Never begin with a 'kill -9' since it cannot be trapped by a process and thus the process has no chance to cleanup temporary files or remove shared memory segments. Instead, use an escalating series of hammers.

Regards!

>ps -fu username | awk 'NR>1{system("kill " $2)}'
In some secomds:
>ps -fu username | awk 'NR>1{system("kill -9 " $2)}'

maybe I missed something here, but how is the PID getting to the kill command??

Hi:

Oops! [ Thanks, OldSchool ]. The suggested code should look like:

PIDS=$(UNIX95= ps -u unixguy -opid=)
for HOW in 1 15 9
do
kill -${HOW} ${PIDS}
sleep 2
done

...I forgot to use the list I created!

Regards!

Hi,


You can kill the ppid of the user.

man 'killall', used during shutdown.
