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.
