如何在Tkinter应用程序上监听终端？

import subprocess
import tkinter as tk

root = tk.Tk()
root.title("终端监听")

output_text = tk.Text(root)
output_text.pack()

def listen_terminal():
    process = subprocess.Popen(["your_command"], stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True)
    while True:
        output = process.stdout.readline().decode("utf-8")
        if output == '' and process.poll() is not None:
            break
        if output:
            output_text.insert(tk.END, output)
            output_text.see(tk.END)

start_button = tk.Button(root, text="开始监听", command=listen_terminal)
start_button.pack()

root.mainloop()
