This question already has an answer here:
Script to check if httpd is on or off
#!/bin/bash
service=service_name
email=user@domain.com
host=`hostname -f`
if (( $(ps -ef | grep -v grep | grep $service | wc -l) > 0 ))
then
echo "$service is running"
else
/etc/init.d/$service start
if (( $(ps -ef | grep -v grep | grep $service | wc -l) > 0 ))
then
subject="$service at $host has been started"
echo "$service at $host wasn't running and has been started" | mail -s "$subject" $email
else
subject="$service at $host is not running"
echo "$service at $host is stopped and cannot be started!!!" | mail -s "$subject" $email

How do I make this script run in background so that it keeps checking if httpd service is on or off and emails a message if it goes off !! ( PS-: I DON'T WANT TO MAKE THE SCRIPT AS A CRONJOB) just like a daemon process which runs in background!! Please Help
If you launch the script with nohup it will run as a daemon.
