Dear Gurus,<br><br>
A BIG thank you to all for your contributions. I have learnt from ALL
your examples. <br><br>
Here is what I have ended up with:- <br><br>
<font color="#0000FF">ps x | grep "[s]sh -f -N" | awk '{ print
$1 }' | xargs kill -p<br><br>
</font>I suppose this would work great if there were only 1 process as a
result of the cmd above. <br><br>
What would happen if there were more than 1 PID from std output?
<br><br>
Will it kill ALL PIDs that were produced from std output?<br><br>
Thanks again. :)<br><br>
Best Regards,<br>
Andrew<br><br>

Dear Gurus,<br><br>
Thanks for all who responded to my previous question. It worked great!
<br><br>
I am now trying to perform a "ps aux | grep "some regular
expression" | cut -f 2 -d ......"<br><br>
I seem to be having 2 problems. <br><br>
1) What delimiter should I define for cut? I've tried " "
(space) but that does not work.<br>
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 <i>regular expression</i>" ?<br><br>
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??<br><br>
$ ps aux | grep "some regular expression" | cut -f 2 -d ......
| xargs kill -9<br><br>
Or something along those lines... <br><br>
Hope someone out there can help me. <br><br>
Thanks again. :)<br><br>
Best Regards,<br>
Andrew<br>

cut -c might be better, or <font color="#FF0000">"awk '{print $N}'
</font>where "N" is the number of the column you
want.<br><br>
If you're killing stuff, perhaps "killall" is what you
want.<br><br>

grep "f\\oo"<br><br>
</font>works nicely.<br><br>
