I'm new to Ruby. I understand Ruby was developed
to make the codes easy to read by Programmers (Humans)
more than to make it abiding by the machine logic.
This is not to say that the foregoing code is faulty
but to show an alternative way.
So, this is how I'd code it.
#!/usr/bin/env ruby
puts $stdin.readlines.sort_by {rand} unless $stdin.eof
In human terms, it says 'put the lines that I got from standard input by sorting
these lines randomly unless it is(excluding) the end-of-file'.
