登录到Raspbian +在python脚本结束时运行python脚本+注销

Question

python脚本仅为自刷新的npyscreen（curses）脚本每1分钟显示一次状态。用户点击ctrl-c后，应该注销。

Answer 1

从this answer：

import os 
import subprocess 

def logoff(): 
    ppid = os.environ['PPID'] 
    subprocess.call(["kill", "-HUP", ppid]) 

你必须抓住KeyboardInterrupt例外：

def main(): 
    try: 
     display_status() 
    except KeyboardInterrupt: 
     logoff() 


def display_status(): 
    pass # your code goes here 

if __name__ == '__main__': 
    main()
