[WBEL-users] Another Shell Scripting Question

[Andrew Vong]

Dear Gurus,

A BIG thank you to all for your contributions. I have learnt from ALL your 
examples.

Here is what I have ended up with:-

ps x | grep "[s]sh -f -N" | awk '{ print $1 }' | xargs kill -p

I suppose this would work great if there were only 1 process as a result of 
the cmd above.

What would happen if there were more than 1 PID from std output?

Will it kill ALL PIDs that were produced from std output?

Thanks again. :)

Best Regards,
Andrew
