Rvm, please tell me if I understood this correctly!

Question

So with RVM, you can run different versions Ruby i.e. 1.8.7 or 1.9.2

Within each ruby version, you can create as many gemsets as you want.

What does the '@' symbol represent in the name? does it do anything special?

i've seen people use:

rvm gemset create xxxx@rails3 or [email protected]

that is just a naming convention correct?

Answer 1

it is just a symbol to separate the Ruby version and the gemset.

you can also use

rvm 1.9.2
rvm gemset use rails238

which is the same as

rvm 1.9.2@rails238

the command

rvm list gemsets 

will tell you the Ruby and gemset you are using
