Of course there is, albeit i have to give the same warnings jiliagre and zaxxon already issued: don't do it, because this is not a sound procedure.

Look at the output of ps aux:

Code:

You need the second column (the PID) for the kill command. Further, you need to disregard the first line because it contains headers rather than data:

Code:
ps aux | <some filter> ... |\
while read junk PID junk ; do
     echo kill -15 $PID
done

Your ps-output may differ slightly from mine (i took mine from an AIX system, not having a HP-Ux system at hand) and you might have to adjust the command slightly. There might be processes which do not respond to signal 15 (this would indicate poor programming) so you might need to change kill -15 <pid> to kill -9 <pid>. If you do so, programs will not be able to clean up after them: shared memory segments, FIFOs and the like as well as temporary files with be left over.

Test thoroughly before you remove the "echo"-statement. Even with thorough testing i suggest to never use this.

I hope this helps.

kill

KILL(1)                                                            User Commands                                                           KILL(1)

NAME

       kill - send a signal to a process

SYNOPSIS

       kill [options] <pid> [...]

DESCRIPTION

       The  default  signal  for kill is TERM.  Use -l or -L to list available signals.  Particularly useful signals include HUP, INT, KILL, STOP,
       CONT, and 0.  Alternate signals may be specified in three ways: -9, -SIGKILL or -KILL.  Negative PID values may be  used  to  choose  whole
       process  groups;  see  the  PGID  column  in ps command output.  A PID of -1 is special; it indicates all processes except the kill process
       itself and init.

OPTIONS

       <pid> [...]
              Send signal to every <pid> listed.

       -<signal>
       -s <signal>
       --signal <signal>
              Specify the signal to be sent.  The signal can be specified by using name or number.  The behavior of signals is explained  in  sig-
              nal(7) manual page.

       -l, --list [signal]
              List signal names.  This option has optional argument, which will convert signal number to signal name, or other way round.

       -L, --table
              List signal names in a nice table.

       NOTES  Your shell (command line interpreter) may have a built-in kill command.  You may need to run the command described here as /bin/kill
              to solve the conflict.

EXAMPLES

       kill -9 -1
              Kill all processes you can kill.

       kill -l 11
              Translate number 11 into a signal name.

       kill -L
              List the available signal choices in a nice table.

       kill 123 543 2341 3453
              Send the default signal, SIGTERM, to all those processes.

SEE ALSO

       kill(2), killall(1), nice(1), pkill(1), renice(1), signal(7), skill(1)

STANDARDS

       This command meets appropriate standards. The -L flag is Linux-specific.

AUTHOR

       Albert Cahalan <albert@users.sf.net> wrote kill in 1999 to replace a bsdutils one that was not standards  compliant.   The  util-linux  one
       might also work correctly.
