The version command for ruby is:

jesus@jesus-laptop:~$ ruby -v
ruby 1.8.6 (2007-09-24 patchlevel 111) [i486-linux]

-e is used to run ruby code. Like:

jesus@jesus-laptop:~$ ruby -e"puts 'hi'"
hi

It will try to evaluate what is passed after the -e. So you do:

jesus@jesus-laptop:~$ ruby -version
ruby 1.8.6 (2007-09-24 patchlevel 111) [i486-linux]
-e:1: undefined local variable or method `rsion' for main:Object (NameError)

it will do the -v part and then when trying to do the -e part it will
try to evaluate rsion, which obviously results in an error.

Jesus.
