shell执行jar包相关操作指南

第一次完整的写shell脚本，之前都是写一些简单的操作。
关于微服务jar包的启动，停止，重启，全部启动，全部停止，全部重启以及修改jar包内文件后启动的相关脚本
稍微记录下：

cd /opt/micro-service/

#输入要进行的操作，启动jar
echo "you need todo?(start/stop/status/restart/startAll/stopAll/restartAll/upstart)"
read todo

#检查程序是否在运行
is_exist(){
  pid=`ps -ef|grep $jarName|grep -v grep|awk '{print $2}'`
  #如果不存在返回1，存在返回0     
  if [ -z "${pid}" ]; then
   return 1
  else
    return 0
  fi
}

#修改启动
upstart(){
  #输入要操作的jar包
  echo "Please Input jar Name:(servcie/servcie.jar)"
  read jarName

  is_exist
  if [ $? -eq 0 ]; then
    echo "${jarName} is already running. please stop"
  else
    jar tvf $jarName |grep $fileName
    #选择正确的文件路径进行修改
    echo "Query out as follows,Please select the copy you want"
    read oldFilePath
    #解压jar内文件
    jar xvf $jarName $oldFilePath
    sleep 1
    #输入jar外替换文件路径
    echo "Please Input replace file path:(like:config/config.properties)"
    read newFilePath
    #替换文件
    cp $newFilePath $oldFilePath
    echo "Replace success!"
    #压缩回jar内
    jar uvf $jarName $oldFilePath
    sleep 2
    #启动
    java -jar $jarName &
  fi
}

#启动
start(){
  #输入要操作的jar包
  echo "Please Input jar Name:(servcie/servcie.jar)"
  read jarName
  is_exist
  if [ $? -eq 0 ]; then
    echo "${jarName} is already running. pid=${pid}"
  else
    java -jar $jarName &
  fi
}

#停止
stop(){
  #输入要操作的jar包
  echo "Please Input jar Name:(servcie/servcie.jar)"
  read jarName
  is_exist
  if [ $? -eq "0" ]; then
    kill -9 $pid
    ps -ef|grep java
  else
    echo "${jarName} is not running"
  fi 
}

#状态
status(){
  #输入要操作的jar包
  echo "Please Input jar Name:(servcie/servcie.jar)"
  read jarName
  is_exist
  if [ $? -eq "0" ]; then
    echo "${jarName} is running. Pid is ${pid}"
  else
    echo "${jarName} is NOT running."
  fi
}

#重启
restart(){
  #输入要操作的jar包
  echo "Please Input jar Name:(servcie/servcie.jar)"
  read jarName
  stop
  sleep 5
  start
}

#全部启动
startAll(){
  for FILENAME in $(ls *jar);
  do 
    pkill -9 $FILENAME
  done
}

#全部停止
stopAll(){
  for FILENAME in $(ls *jar);
  do 
    pid=`ps -ef|grep $FILENAME|grep -v grep|awk '{print $2}'`
    java -jar $pid & ; 
  done
}

#全部重启
restartAll(){
  stopAll
  sleep 10
  startAll
}
