While this will work, it may be useful to know that what you have got is
a DOS text file probably downloaded by ftp in *binary* mode, or served
by some http server with wrong content type info.

There are two convenient utilities 'dos2unix' and 'unix2dos' that
convert such text files from DOS format to Unix format and back. At the
shell prompt type

dos2unix foo.txt

to convert and replace foo.txt, and
               ^^^^^^^ 
unix2dos foo.txt 

to get back all those ^M 's.

It has one or two useful command line options such as --keepdate. See
the man page.
