TKinter + display of a shell command return

[Yann.K]

Hello.

Using Tkinter, i would create a widget which display a shell command return.
This return is long, and i would display a real time display (like with the
tail -f commande on Linux)

I think to use the text widget.
I have no problem to execute the command, but how to display, in a
*real-time* fashion the shell retrun?

If you have a track or an idee...

Thanks for your help.
