shell-检测服务是否运行，并记日志

目的：每隔*分钟检测服务是否运行；若运行中，则记录执行的进程名称；若不运行，记录当前时间

shell:

#!/bin/bash

date=`date +%Y%m%d`
log=/home/mono_${date}.log
err_log=/home/ERR_${date}.log

if [ ! -f ${log} ]; then
	touch ${log}
fi

if [ ! -f ${err_log} ]; then
	touch ${err_log}
fi

PATH=PATH:/sbin:/bin:/usr/bin

cmd=`ps -ef | grep mono | grep -v grep | wc -l`

if [ ${cmd} -eq 1 ]; then
	date >> ${err_log}
else
	date >> ${log}
	ps -ef | grep mono >> ${log}
	echo "*************************" >> ${log}
fi

crontab -e
