Question

Stumbled across the ∴ operator in some of the rvm install scripts and couldn’t seem to locate information on what it does? Is there documentation on this somewhere?

Answer 1

I’ll guarantee it’s not a bash thing. UNIX is famous for the terseness of its commands but even it wouldn’t go that far 🙂

It’s possible that RVM may create a script or executable with that name so that entering it on the command line may do something but, if that’s so, it’s a good reason for me to avoid RVM.

However, since the context seems to be lines like:

∴ bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-head )
∴ rvm update
∴ gem update rvm && rvm-install

I would suggest it’s the prompt in use for the shell rather than a command.
