in reply to How do i obtain the PID of a program already running.

ps -C program_name

From the Chatterbox earlier today, you were wanting to kill all the apache PID's with Perl... 

shell> ps -C httpd | perl -pe '($_)=/(\d+)/;`kill -9 $_`'
That should work as root

Enjoy!

    I can't update my own posts... grrr!

    Change perl -pe to perl -ne actually... 

    ps -C httpd|perl -ne'($_)=/(\d+)/;`kill -9 $_` if $_'
    That seems better to me.
