终止使用子进程打开的 gnome 终端

问题描述

使用子进程和命令 'gnome-terminal -e bash' 我可以根据需要打开一个 gnome 终端(并让它一直存在).这可以通过

Using subprocess and the command 'gnome-terminal -e bash' I can open up a gnome-terminal as desired (and have it stick around). This is done with either

p=subprocess.Popen(['gnome-terminal', '-e', 'bash'])

或

p=subprocess.Popen(['gnome-terminal -e bash'], shell=True)

但我无法使用 p.terminate() 或 p.kill() 关闭终端.据我了解，这在使用 shell=True 时有点棘手，但我没想到会遇到问题.

but I cannot close the terminal using p.terminate() or p.kill(). From what I understand, this is a little trickier when using shell=True but I did not expect to run into problems otherwise.

推荐答案

要终止终端及其子进程(在同一进程组中):

To terminate a terminal and its children (in the same process group):

#!/usr/bin/env python
import os
import signal
import subprocess

p = subprocess.Popen(['gnome-terminal', '--disable-factory', '-e', 'bash'],
                     preexec_fn=os.setpgrp)
# do something here...
os.killpg(p.pid, signal.SIGINT)

• --disable-factory 用于避免重复使用活动终端，以便我们可以通过 subprocess 句柄杀死新创建的终端
• os.setpgrp 将 gnome-terminal 放在它自己的进程组中，以便 os.killpg() 可用于将信号发送到本组
• --disable-factory is used to avoid re-using an active terminal so that we can kill newly created terminal via the subprocess handle
• os.setpgrp puts gnome-terminal in its own process group so that os.killpg() could be used to send signal to this group
