Free Unix and Linux Shell Servers

This is an updated list of free shell providers. None of these servers is mine and I'm only providing you with information regarding them. If you know of any, please email me and I'll add them.
DISCLAIMER: I'm not responsible for (1) anything you do with these servers or (2) if your code gets lost or (3) someone steals your code on these servers. Use them responsibly.

UPDATE: Grex.org closed its doors on 15th April 2023. I remember using it while in college. Sadly, they closed down.
