You can use postmodern's chruby to change the current Ruby:
chruby 1.9
chruby
* ruby-1.9.3-p429
ruby-2.0.0-p195
It also supports auto-switching based on a .ruby-version
file.
Question
After installation of multiple rubies by ruby-install, how to use a specific installation of ruby? Should a ruby be accessed by absolute path, or depends on some environment path like rvm
?

OTHER TIPS
Have you considered using rbenv which wraps around that to provide an rvm
-like interface?
Using those directly is not something I'd consider practical.
