This command might help when you see error messages like this:

-bash: $'then\r': command not found

Windows style newline characters often cause issues in Cygwin.

The?dos2unix?command modifies newline characters so they are Unix / Cygwin compatible.

NOTE:?the dos2unix command modifies files?in place, so take precaution if necessary.

If you need to keep the original file, you should back it up first.
