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 [dgardella@gmail.com]
# 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
