I would like to know an email that I can run on terminal. For free. I do not want to use theworld.com because it costs money. Anyone know any free ones?
What you need to do is install alpine or elm, as stated above, and then those programs act as text-based, terminal e-mail clients that will retrieve your e-mail from your GMail account.
Here are some instructions on how to set that up (after you install alpine).

Also, as someone who once wanted to do something similar for the sake of being all retro, I have to say that the novelty really wore off after a short while. E-mail that is pure text-only is getting rarer and rarer, and continuing to use alpine except for some very specific edge cases kinda gets silly after a while. Of course, you might have one of those very specific edge cases, and that's fine. But for 99.99% of users out there, there are tools built into your Mac that are so much better at it, including Mail and your web browser.
Theworld.com does not require you to download anything on my mac and all my friend has to do is do "ssh -something username@theworld.com" and then it will ask for your password. The only problem with the world is, it costs money.
I guess that I feel a little sad for you then.
