Emacs is garbled by output of a background process running in the same terminal emulator

Question

My Emacs is running in foreground in terminal emulator, where I am also running some background processes.

My Emacs is garbled by the stdout and stderr output of the background process.

Besides redirecting the stdout and stderr output of the background process to /dev/null, is there another way to make my emacs not bothered by the background process? For example, can something be done on the emacs side?

Thanks.

Answer 1

No, there isn't, if you don't want to silence your background processes.

You could use something like tmux or GNU Screen for your background processes.

Or you could run them in another terminal.

But Emacs has no way of knowing that some other process is outputting characters to the terminal, as far as I know.

Answer 2

In emacs, Ctl-L will refresh the screen, removing any extra stuff written by your background process.

If the background process only emits stuff every once in a while, then you can just refresh each time.
