Shell Programming and Scripting

I think what you need would more likely looks like something like this :

Code:

ps -ef | grep Proc | egrep -ve 'grep|PID' | awk '{print $2}' | xargs kill

(of course this should be adjusted depending on the output you have and the result you expect)

The default signal for kill is 15 (SIGTERM) this sends a "request" to the process to terminate. So locked-up processes may not respond to this request in which case you may need to use -9 (SIGKILL) this forces the process to end, giving it no chance to do anything futher (eg cleanup, flush file buffers and the like).

Your script could sleep for a while to give the processes time to exit normally and the fetch a new list of those still running and kill the with -9 to ensure they are all gone.

Code:

# after the above
sleep 10
Process=$(ps -ef | grep [P]roc | awk '{ print $2}')
if [ -n "$Process" ]
then
    kill -9 $Process
fi

Edit -- ctsgnb xargs still executes kill even in the stdin is empty. GUN xargs offers the -r option to aviod this but it's not POSIX so will not be available in all systems.

Thank you guys all for the assistance. I am still learning this and so far, this forum has been fantastic.
