Fedora /usr/bin/ruby stub to allow choosing Ruby runtime. Similarly to [rbenv] 1 or [RVM] 2, it allows non-privileged user to choose which is preferred Ruby runtime for current task.

The following are supported runtimes under Fedora:

• Ruby - /usr/bin/ruby-mri
• JRuby - /usr/bin/jruby

To run a specific runtime, use:

ruby _mri_ [params]
ruby _jruby_ [params]

The default is _mri_.

To run Ruby executables with shebang, such as 'gem', you can also use these:

gem _mri_ install foo
gem _jruby_ install foo

Or you can set environment variable RUBYPICK like this:

RUBYPICK=_mri_
RUBYPICK=_jruby_

and then MRI, resp. JRuby will be used for all ruby invocations. This is still overriden by using the parameter as mentioned above.

If you don't want to use rubypick, you can always fall back to using the above binaries.
