If Ruby is installed, then

ruby yourfile.rb

where yourfile.rb is the file containing the ruby code.

or

irb

to launch an interactive Ruby environment where you can type lines of code and see results immediately.

You can run ruby commands on the same line with the -e flag:

 ruby -e "puts 'hi'"

See the man page for more information.
