The (^M -Control M) characters are displayed because Windows is stupid
and didn't do the sensible thing for End Of Line for plain text files.
Linux/Unix uses a Carriage Return (CR) followed by a Line Feed (LF) to
do an EOL. A Google search for "Control M Character" will bring up a lot
of web sites dealing with explaining this.
You need to run "dos2unix" or "unix2dos" on your script to convert the
EOL to the proper OS formatting when transferring between real
Linux/Unix machines and Windows machines. These utilities are available
in the Cygwin utilities download (look for it), but I'm not sure they
are included in the basic default packages.
