背景
最近在Windows 10上使用Linux子系统，发现它有一个非常坑爹的特点：Linux子系统是没有开机关机状态的，每次进入Bash shell就自动载入，退出后Linux子系统的所有进程都会被关闭，如果你撞了Mysql之类的服务要想随时运行的话就要保持Bash shell的随时开启，更坑的是这些服务并不会随之进入Bash shell而自动启动， 我只好写一个Python脚本用于管理这些服务。

Python3, argparse module
代码
from os import system
from argparse import ArgumentParser
def start_service(service):
system("service {} start".format(service))
def stop_service(service):
system("service {} stop".format(service))
def restart_service(service):
print(service)
system("service {} restart".format(service))
def manage_service():
services = []
services.append("xinetd")
services.append("lighttpd")
return services
def set_args():
parser = ArgumentParser()
parser.add_argument("service", help = "the service to be managed.")
parser.add_argument("-s", "--start", help = "start the service(s).", action = "store_true")
parser.add_argument("-r", "--restart", help = "restart the service(s).", action = "store_true")
parser.add_argument("-p", "--stop", help = "stop the service(s).", action = "store_true")
return parser.parse_args()
def deal(args,services):
global start_service, restart_service, stop_service
services = services if not args.service else services if args.service == "all"else [args.service]
operation = start_service if args.start else restart_service if args.restart else stop_service
for service in services:
operation(service)
if __name__ == "__main__":
deal(set_args(),manage_service())运行

Python脚本还是比shell脚本好写很多啊。
