I added a quick-and-dirty example how to do this below; in the example I used the command "cdrdao disk-info" on linux, which when no disc is in the drive will try for about 10 sec. to make sense of the non-existing disc before giving up, printing "Unit not ready" to stderr for 10 times in the process which I use here to draw the progress bar. The gui remains responsive without having to use threads (as you can see when you hit the stop button). If you don't need any external command but just want to compare file sizes, the code may become even simpler. I hope this helps Michael #################################################################### from tkinter import * from tkinter import ttk from subprocess import Popen, PIPE import os, fcntl root = Tk() root.pipe = None f = Frame(root) f.pack(fill='both', expand=1) p = ttk.Progressbar(f) p.pack(padx=100, pady=(100,10)) MSG = '' def update_progress(msg): global MSG print(msg) MSG += msg perc = MSG.count('Unit not ready') * 10 p.configure(value=perc) def update(): sts = root.pipe.poll() try: out = root.pipe.stderr.read() except IOError: out = b'' if out: update_progress(out.decode()) if sts is None: root.after(200, update) else: del root.pipe root.pipe = None p.configure(value=100) print('Process finished with status %d' % sts) def kill(): if root.pipe: try: os.kill(root.pipe.pid, 15) except: pass def start(): global MSG MSG = '' p.configure(value=0) root.pipe = Popen(('cdrdao', 'disk-info'), stdout=PIPE, stderr=PIPE) fcntl.fcntl(root.pipe.stdout.fileno(), fcntl.F_SETFL, os.O_NONBLOCK) fcntl.fcntl(root.pipe.stderr.fileno(), fcntl.F_SETFL, os.O_NONBLOCK) root.after(200, update) Button(text='stop', command=kill).pack(side='bottom', pady=20) Button(text='start', command=start).pack(side='bottom', pady=20) root.mainloop() #################################################################### .-.. .. ...- . .-.. --- -. --. .- -. -.. .--. .-. --- ... .--. . .-.
