If that's an issue (I've never met a server like that, not to mention one like that and I couldn't change the setting) then wouldn't you rather use this?

  while [ true ]; do sleep 1000; done

Just using:

  sleep 1000; exit

means you can't make new connections after 17 minutes.

Yes, in fact I use the first one (while true; sleep; ls) but I thought the second is more succint. Anyone interested can make a loop. Please notice that most of the snippets aren't meant to be copied & pasted, but rather analyzed and understood by the user.

Ah, sometimes that's a hard line to draw since often the people that know enough to understand not to take it literally don't really need the pointer in the first place. :)

I enjoyed your list.
