Thanks for the help.

File.rename is behaving strangely.  The file name ended up have an extra
non-printing character at the end.  Instead of naming the file "filename"
it names it "filename^J".

I don't know what character "^J" is.

I'm on a SPARC computer (in case that matters).

I got the probram working by just doing `mv old.txt #{filename}`, but I
thought I'd mention this apparent bug.
