Thanks. That did it. Here's another, no doubt equally stupid question.

On p. 16 of Programming Ruby is given

ARGF.each {|line| print line  if line =~/Ruby/ }

which is supposed to print the inputted lines which contain "Ruby"

The while loop example in the book runs as expected but this ARGF
one-liner doesn't seem to do anything.

Thanks,
