通过python与bash交互，无需终止

import subprocess

# 执行bash命令
def run_bash_command(command):
    process = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True)
    output, error = process.communicate()
    return output.decode('utf-8'), error.decode('utf-8')

# 与bash交互
def interact_with_bash():
    while True:
        # 获取用户输入的命令
        command = input("请输入要执行的命令：")
        # 执行命令
        output, error = run_bash_command(command)
        if error:
            print("执行命令出错：", error)
        else:
            print("命令输出：", output)
