批量启动jar脚本

批量启动jar脚本

#!/bin/bash
#####################################################Environment Setting#######################################################

# linux命令用法：

# 1.启动所有jar程序：sh service.sh start all
# 2.停止所有jar程序：sh service.sh stop all
# 3.重启所有jar程序：sh service.sh restart all
# 4.单独启动、停止、重启某个jar程序：把最后面的all替换为某个jar程序的代码即可
