检查httpd是打开还是关闭的脚本

Question

检查httpd是打开还是关闭的脚本

#!/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  
fi  
fi

如何让这个脚本在后台运行，以便它继续检查httpd服务是打开还是关闭，并在消息发出时通过电子邮件发送消息!! （PS-：我不想把这个脚本作为一个CRONJOB）就像一个在后台运行的守护进程！请帮忙

如果使用nohup启动脚本，它将作为守护程序运行。
