shell脚本检查服务状态

#!/bin/bash
if [ "$#" = 0 ]
then
echo "Usage 
bobbin@theitroad:/$./service.sh apparmor
Service apparmor is not running
Found startap script /etc/init.d/apparmor. Start it? Y/n ? Y
Starting service...
* Starting AppArmor profiles [OK]
 "
exit 1
fi
service=
is_running=`ps aux | grep -v grep| grep -v "##代码##" | grep $service| wc -l | awk '{print }'`
if [ $is_running != "0" ] ;
then
echo "Service $service is running"
else
echo
initd=`ls /etc/init.d/| grep $service | wc -l | awk '{ print  }'`
if [ $initd = "1" ];
then
startup=`ls /etc/init.d/| grep $service`
echo -n "Found startap script /etc/init.d/${startup}. Start it? Y/n ? "
read answer
if [ $answer = "y" -o $answer = "Y" ];
then
echo "Starting service..."
/etc/init.d/${startup} start
