You want:  if line == 'w s'

#{line} only makes sense in a double quoted string,
without quotes you are starting a comment here!

I think you should read up on some basic Ruby syntax,
try e.g. http://pine.fm/LearnToProgram/.

Generally, placing puts statements like 'puts your_var.inspect'
or 'p your_var' just before "critical" places in your code could
help you understand what's going wrong.

And you should develop a habit of testing (simplified) code
snippets with irb.
