Full Discussion: Stopping A process

Killing a process based on the process name can be tricky.
The process name might be a substring of another process.
And it could exist more than once.

This should work:

PID=`ps -ef | grep -w ${PROCNAME} | awk '{print $2}'`
kill -9 $PID

This will kill all occurences of the PROCNAME.

I have come across the fact that the process name you want to kill is actually a process with some arguments, like "httpd -f".
In this case it can't hurt to use quotes:

PID=`ps -ef | grep -w "${PROCNAME}" | awk '{print $2}'`
kill -9 $PID

Would you like to only kill the last occurence of the PROCNAME you may use:

PID=`ps -ef | grep -w "${PROCNAME}" | awk 'END {print $2}'`
kill -9 $PID

Perhaps others have better suggestions as I am still learning too :-)

kill

KILL(1) 						      General Commands Manual							   KILL(1)

NAME

       kill, broke - print commands to kill processes

SYNOPSIS

       kill name

       broke

DESCRIPTION

       Kill  prints  commands  that  will cause all processes called name and owned by the current user to be terminated.  Use the send command of
       81/2(1), or pipe the output of kill into rc(1) to execute the commands.

       Kill suggests sending a kill note to the process; the same message delivered to the process's ctl file (see proc(3)) is a surer,  if  heavy
       handed, kill, but is necessary if the offending process is ignoring notes.

       Broke  prints  commands	that  will  cause all processes in the Broken state and owned by the current user to go away.  When a process dies
       because of an error caught by the system, it may linger in the Broken state to allow examination with a debugger.  Executing  the  commands
       printed by broke lets the system reclaim the resources used by the broken processes.
