Question Kill an specific process ID using the KILL and GREP commands
Good afternoon

I need to KILL a process in a single command sentence, for example:

Code:
kill -9 `ps -aef | grep 'CAL255.4ge' | grep -v grep | awk '{print $2}'`

That sentence Kills the process ID corresponding to the program CAL255.4ge.

However it is possible that the same program CAL255.4ge is executed by 2 different users ID, for example:

Code:
/nfs/nfs3/fuentes/per>bgr

There are 2 users
Code:
wilruiz0

and
Code:
wilruiz2

So I need to tell the UNIX to KILL the process, specifying both the PROGRAM NAME and the USERID.

I guess that would mean to improve the GREP sentence to search for 2 string patterns instead of one.

That would be:

Code:
kill -9 `ps -aef | grep -i -e 'CAL255.4ge' -e 'wilruiz0' | grep -v grep | awk '{print $2}'`

It is not working because it is searching for the patterns as an OR instead of AND where the 2 strings patterns are needed to meet.

Please help.
