[WBEL-users] Another Shell Scripting Question

Dear Gurus,

Thanks for all who responded to my previous question. It worked great!

I am now trying to perform a "ps aux | grep "some regular expression" | cut 
-f 2 -d ......"

I seem to be having 2 problems.

1) What delimiter should I define for cut? I've tried " " (space) but that 
does not work.
2) I usually get 2 processes listed. The actualy one I'm looking for and 
the line I just executed. How can I exclude the 2nd process which also 
contains the same "grep regular expression" ?

The above is part of a longer one-liner command I'm trying to construct. I 
basically want to kill a specific process and I just want to obtain the PID 
for it. So, it may end up looking like this??

$ ps aux | grep "some regular expression" | cut -f 2 -d ...... | xargs kill -9

Or something along those lines...

Hope someone out there can help me.

Thanks again. :)

Best Regards,
Andrew
