Cisco IOU: Shutting Down the IOU Processes

This is a simple bash script that looks for all IOU processes that have been started with the ‘wrapper-linux’ utility and then kills those processes.

In short, it does

1. a process status ‘ps -ef’ ,
2. the output is filtered with grep for the term wrapper or rapper,
3. awk then selects the second element of the line ( which is the process number)
4. then xargs is used to build the list into command line output


#!/bin/bash
#
# Stop IOU Processes
#
PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:~/bin
export PATH
#
ps -ef | grep [w]rapper | awk '{ print $2 }' | xargs kill
#
exit 0
