So when you ftp a file from windows to unix sometimes you will see ^M characters at the end of each line. This is because the files has been transferred as a binary file versus an ascii file.

Simply open the text file in the vi editor, and type
This will change the file format from dos to unix based and the carriage return problem should be solved!
