Re: [gentoo-user] Running a program on a headless computer ?

[Sid S]

I was deciding whether to reply earlier, and my worst fears were realized:
you plan to start this automatically with no human intervention.

Here is a snippet which should do what you want: `nohup my-program >
/dev/null 2>&1 &`
Screen and tmux will/should work, but at the very least I would suggest
wrapping the program with a program of your own where you execute the other
and have more and explicit control over the file descriptors.

The best solution is modifying your programs to work headlessly. This also
means you can ensure logging is done properly (you were logging, right?),
and not in some ad-hoc fashion like reading all the messages your black box
produces and keeping the ones that "look important."

It's tempting to glue some things together with the shell, but I would
avoid reliance on programs which are not yours as much as possible. "Not
Invented Here" is often (rightfully) mocked, but this is one of the
situations in which it has some relevance.
