Hello,

Suppose, If an user initiated a process which consumes lot of real memory and it effetcs other important processes running on the system.

So, I want to kill the processes which are initiated by an user, then
How could I do this?

Expecting your response!

Regards,
Kiran

You may use topas command,

For example above, topas is your top process, which owns by root,
You may kill that process already.

root@AIXMODEL:/ # ps -ef|grep 7340100 root 7012426 6684842   0 17:46:18  pts/1  0:00 grep 7340100 root 7340100 8650848   0 17:44:39  pts/0  0:00 topas

Hope this helps

Of course that'll kill every process started by this user.

If you want to kill ALL processes owned by a particular user, say apache, then this will work but it will not kill any ksh so you will need to kill those with a kill -9 but it's best to tell the user(s) to get out themselves rather than doing the -9.

1. ps -fuapache|grep -v PID|awk '{print $2}'|xargs -t -i kill {}

If you just want to kill a subset of processes owned by a user, use grep to narrow things down. e.g.

1. ps -fuapache|grep -v PID|egrep '<put a unique search string here>'|awk ...
