force file write in dos format

[Martin DeMello]

Is there any built-in way to force File.puts to use dos line endings,
regardless of the platform under which the program is running?

Use IO#print instead of IO#puts and set $\, the default output record
separator:

Thanks!

If I undertand correctly what you want your program is going to
explicitly output pairs "\r\n".

If that's the case, in addition to the recommendation about IO#print
already given take into account that the io needs binmode. Otherwise,
on CRLF platforms you'd end up with "\r\r\n" on disk, which would be
wrong. That's because the single "\n" in "\r\n" gives itself a pair
"\r\n" in text mode. So IO#print CRLF in binmode is the complete
portable solution.

Good point. As of now this will only ever be run on a linux box, but
it certainly doesn't hurt to future-proof it.
