如果占用时间太长，则中断python中的shell进程

import subprocess
import signal
import os
import time

def run_command_with_timeout(command, timeout):
    process = subprocess.Popen(command, shell=True)
    start_time = time.time()

    while True:
        if process.poll() is not None:
            return process.returncode
        if time.time() - start_time > timeout:
            os.kill(process.pid, signal.SIGTERM)
            return -1
        time.sleep(0.1)

# 示例命令
command = "sleep 10"
timeout = 5

result = run_command_with_timeout(command, timeout)
if result == -1:
    print("进程被中断")
else:
    print(f"进程正常结束，返回码: {result}")
