Hi,

I know that the answer to this is very simple, since I saw somebody do it some time back..but I forgot how.

The problem is, I have multiple instances of the same program running simultaneously and I want to kill them all in a single command.

I know that it can be done using awk '{print $2}' in combination with ps and kill but I am not able to formulate the exact command.

The process in question (to be killed) is xterm.

will deeply appreciated all help.

if you have pkill it is a doddle....

Will pkill kill only the instance that a user has permission to kill ?

user A can run the instance proc p1
and user B can also run the same instance proc p1

will pkill identify only the instances from user A and kill only those instances of proc p1

( may be something like ps -fu $user )

It can't kill the ones you don't.

Well, that is true.
Am interested to know whether it would skip it as such or will throw an error stating unable to kill the other instance.

I will check that !

I don't have pkill.

Yet, I know the answers a doddle if you can combine kill, ps -fu, and awk '{print $2}' (with ps).

Only, am not able to do it myself, and waiting for a shell expert to do it for me..

As long as you know the name of the process take a look at the 'killall' command.
