shell執行jar包相關操作指南

第一次完整的寫shell腳本，之前都是寫一些簡單的操作。
關於微服務jar包的啟動，停止，重啟，全部啟動，全部停止，全部重啟以及修改jar包內文件后啟動的相關腳本
稍微記錄下：

cd /opt/micro-service/

#輸入要進行的操作，啟動jar
echo "you need todo?(start/stop/status/restart/startAll/stopAll/restartAll/upstart)"
read todo

#檢查程序是否在運行
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
}

#修改啟動
upstart(){
  #輸入要操作的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
    #選擇正確的文件路徑進行修改
    echo "Query out as follows,Please select the copy you want"
    read oldFilePath
    #解壓jar內文件
    jar xvf $jarName $oldFilePath
    sleep 1
    #輸入jar外替換文件路徑
    echo "Please Input replace file path:(like:config/config.properties)"
    read newFilePath
    #替換文件
    cp $newFilePath $oldFilePath
    echo "Replace success!"
    #壓縮回jar內
    jar uvf $jarName $oldFilePath
    sleep 2
    #啟動
    java -jar $jarName &
  fi
}

#啟動
start(){
  #輸入要操作的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(){
  #輸入要操作的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 
}

#狀態
status(){
  #輸入要操作的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
}

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

#全部啟動
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
}

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