How to remove invisible character?

[James Mcphee]

So you have a carriage {CR}{LF} instead of just {LF}.  That's the windows
return characters instead of just the unix one.  (Mac uses just the {CR}).

You can crush that in a couple ways.  The dos2unix utility works fine.  You
could also use sed or vi to snip it.  It shows up as a ^M if you cat -vet or
do a :set list in vi.
