The problem is that you're trying to use DOS/Windows text format on Linux/Unix/OSX machine.

In DOS/Windows text files a line break, also known as newline, is a combination of two characters: a Carriage Return (CR) followed by a Line Feed (LF). In Unix text files a line break is a single character: the Line Feed (LF).

Dos2unix can convert for you the encoding of files, in example:

dos2unix yourfile yourfile

For help, run: man dos2unix.
