Great script, but needed it the other way around

Great script, but I needed a script to check if a file does not exist. On my Ubuntu server I want to check if the file /var/run/reboot-required does not exist and warn me if it does (to notify me the server needs a reboot). To check this I just had to switch the output statements of the script, which I saved as check_file_notexists. Hereby the altered code for check_file_notexists: #! /bin/bash # # Author : Diego Martin Gardella [[email protected]] # Modified by Erling Ouweneel to switch OK and CRITICAL # # Desc : Plugin to verify if a file does not exist # # PROGNAME=`basename $0` PROGPATH=`echo $0 | sed -e 's,[\/][^\/][^\/]*$,,'` . $PROGPATH/utils.sh if [ "$1" = "" ] then echo -e " Use : $PROGNAME -- Ex : $PROGNAME /etc/hosts n " exit $STATE_UNKNOWN fi if [ -f $1 ] then echo "CRITICAL - $1 : EXISTS :: `head -3 $1`" # shows the first three lines of the file exit $STATE_CRITICAL else echo "OK : $1 Does NOT exists " exit $STATE_OK fi
