$0 == __FILE__ idiom for Unix only?

ruby-talk

I have been using the Ruby idiom ‘if $0 == FILE … end’ for
ages on Linux and now that I have to use some of my scripts on WIndows
it looks like this test doesn’t work?

Is this supposed to work on Unix/Linux only or on all platforms??

Thanks

I don’t have acess to a windows system, but it works on windows
dependening upon how program is called. That is, through

ruby myrubyprog.rb

or through the autolaunching of .rb files…IIRC.
