Ruby - get the file being executed

Question

I'm trying to get a reference to the script passed to the ruby interpreter. For example, if I'm running ruby foo.rb I want to get a reference to the foo.rb file.

I think in Python this would be accessible through sys.argv[0]. One could call __FILE__ however this is not solution I'm looking for, since __FILE__ yields the file inside which the currently execute code lies in.

Is there any way to do that?

Answer 1

Use methods in the File class to manipulate FILE

Inside test.rb, I have

puts __FILE__ puts File.dirname(__FILE__) puts File.basename(__FILE__) 

When you run,

ruby a/b/test.rb 

You get

a/b/test.rb a/b test.rb
