如何使用 python 向 iTerm2 session 中的正在运行的进程发送 SIGINT 信号？

Question

I'm trying to automate the restarting of several servers running in iTerm2 tabs using iTerm2's Python API . I can get a reference to the sessions, and issue commands to them (with async_send_text ), but I can't figure out how to send SIGINT signals to them so I can issue the restart commands.

I've seen a few answers using AppleScript, but it seems like this should be possible in python.

You can use os.kill() to send signals to a process as long as you have the process ID:

import os
import sys

os.kill(<PID>, signal.SIGINT)

This should work even when the process is in running in a terminal emulator.
