Special Characters [^M] appearing at the end of line in file if seen on unix but not when seen in eclipse
You have saved your text file as a DOS/Windows text file. Some Unix text editors do not interpret correctly DOS/Windows newline convention by default. To convert from Windows to Unix, you can use dos2unix, a command-line utility that does exactly that. If you do not have that available in your system, you can try with tr, which is more standard, using the following invocation:
tr -d '\r' < input.file > output.file
They are probably Windows carriage return characters. In Windows, lines are terminated with a carriage-return character followed by an end-of-line character. On Unix, only end-of-line characters are normally used, therefore many programs display the carriage return as a ^M.
You can get rid of them by running dos2unix on the files. You should also change your Eclipse preferences to save files with Unix end of lines.
