Hi,

suppose I have,

require "redgreenblue"
in 
runme.rb

Is there a way I can tell which 
redgreenblue.rb file will get pulled in to runme.rb
at run time?

Most UNIX shells have a 'which' builtin command which 
offers similar behavior.

If I type 
which runme
the builtin which command will tell which runme file
the shell would run should I choose to run it.

Thanks.
