Question

I want to pipe [edit: real-time text] the output of several subprocesses (sometimes chained, sometimes parallel) to a single terminal/tty window that is not the active python shell (be it an IDE, command-line, or a running script using tkinter). IPython is not an option. I need something that comes with the standard install. Prefer OS-agnostic solution, but needs to work on XP/Vista.

I’ll post what I’ve tried already if you want it, but it’s embarrassing.

Answer 1

A good solution in Unix would be named pipes. I know you asked about Windows, but there might be a similar approach in Windows, or this might be helpful for someone else.

on terminal 1:

mkfifo /tmp/display_data
myapp >> /tmp/display_data

on terminal 2 (bash):

tail -f /tmp/display_data

Edit: changed terminal 2 command to use “tail -f” instead of infinite loop.
