Hi,

U can kill the process by the following command.

kill -9 process-id (PID)

Here the process id (PID)

its not that i want to kill the pids individually..
but i want to kill all the pids obtained from the above command with a compund command or a script

Try this:

kill -9 `pgrep app_you_want_to_kill`

pgrep will return a list of processes IDs for the name you specify.

but there nothin like pgrep in HP-UX and so it wont work out.

I'm guessing the most portable way to do this is like

Code:

ps -awwx |grep "$stuff_to_grep_for"|awk '{print $1}'|xargs kill

Check if ww does for you what it does for me, that is cause the output not to be truncated at 80 columns.

On linux there's "killall" which takes executable names itself. E.g.g "killall xterm" kills all xterms that I'm allowed to kill. Does it exist on HP-UX? If not, stick with aluser's solution.

There is a killall for HPUX, but do not use it. It is really meant for something slightly different - it doesn't take an argument like that.

aluser · 06-30-2004, 12:12 PM

haha is that the killall that *kill*s *all* processes?

ps -C name_of_program -o pid= | xargs kill
