Linux 创建伪守护进程

#! /bin/sh

#进入程序目录
cd xxxxx

#AppName 为你的程序名字
PRO_NAME=AppName
PRO_EXE=./AppName

while true ; do

#    用ps获取$PRO_NAME进程数量
NUM=`ps aux | grep ${PRO_NAME} | grep -v grep |wc -l`
#  echo $NUM
#    少于1，启动进程
if [ "${NUM}" -lt "1" ];then
echo "${PRO_NAME} was killed"
${PRO_EXE}
#    大于1，杀掉所有进程，重启
elif [ "${NUM}" -gt "1" ];then
echo "more than 1 ${PRO_NAME},killall ${PRO_NAME}"
killall -9 $PRO_NAME
${PRO_EXE}
fi
#    kill僵尸进程
NUM_STAT=`ps aux | grep ${PRO_NAME} | grep T | grep -v grep | wc -l`

if [ "${NUM_STAT}" -gt "0" ];then
killall -9 ${PRO_NAME}
${PRO_EXE}

#Sleep 10s
