简洁版:

#! /bin/bash

# author caoxin

# time 2012-10-10

# program : 判断进行是否存在,并重新启动

function check(){

count=`ps -ef |grep $1 |grep -v “grep” |wc -l`

#echo $count

if [ 0 == $count ];then

nohup python /runscript/working/$1 &

fi

}

check behaviors.py

详细版:

#!/bin/bash

#

#调用关闭jboss进程脚本

stopMethodServer.sh

#打印出当前的jboss进程:grep jboss查询的jboss进程,grep -v “grep” 去掉grep进程

jmsThread=`ps -ef | grep gdms | grep jboss | grep -v “grep”`

echo $jmsThread

#查询jboss进程个数:wc -l 返回行数

count=`ps -ef | grep gdms | grep jboss | grep -v “grep” | wc -l`

echo $count

sec=7

#开始一个循环,以判断进程是否关闭

for var in 1 2

do

if [ $count -gt 0 ]; then

#若进程还未关闭,则脚本sleep几秒

echo sleep $sec second the $var time, the JMS thread is still alive

sleep $sec

else

#若进程已经关闭,则跳出循环

echo “break”

break

fi

done

#if [ $count -eq 0 ]; then

# echo “nohup startMethodServer.sh &”

# nohup startMethodServer.sh &

#else

# echo “It’s better to check the thread!!!”

#fi

#调用启动脚本

nohup startMethodServer.sh &
