## Change as per your distro 
_pgrep="/usr/bin/pgrep"
_mail="/usr/bin/mail"

## Add binary list here
_chklist="/usr/bin/php-cgi /usr/sbin/nginx /usr/sbin/lighttpd /usr/sbin/mysqld /usr/sbin/apache2 /usr/sbin/named /usr/sbin/pgsqld"

## yes | no
_sendemail="no"

## Add your email id
_email="your@mobile.email.id.example.com"

## Do not change below
_failed="false"
_service="Service:"

_running() {
	local p="${1##*/}"
	local s="true"
	$_pgrep "${p}" &gt;/dev/null || { s="false"; _failed="true"; _service="${_service} $1,"; }
	[[ "$s" == "true" ]] &amp;&amp; echo "$1 running" || { echo -n "$1 not running"; [[ ! -f "$1" ]] &amp;&amp; echo " [ $1 not found ]" || echo ; }
}

## header
echo "Service status on ${HOSTNAME} @ $(date)"
echo "------------------------------------------------------"

## Check if your service is running or not 
for s in $_chklist
do
	_running "$s"
done

## Send a quick email update (good for cron jobs) ##
[[ "$_failed" == "true" &amp;&amp; "$_sendemail" == "yes" ]] &amp;&amp; { _mess="$_service failed on $HOSTNAME @ $(date)";
