Actually, n or ASCII 10 code (LF) in all of the UNIX world and quite a bit of others is considered newline, while r or ASCII 13 (CR) is useful at creating different whirls, progress bars and other inline ascii animations. Using CR+LF in Unix doesn't hurt as the cursor lands where it was supposed to land anyway.

In the Microsoft world though, you need to use 2 characters to terminate each line as LF moves the cursor 1 character down but doesn't move it to the beginning of the line, so extra CR is required.

So, YMMV, you may need LF or CR+LF, but no matter what, CR (13) by itself won't suffice unless your intention is to overwrite existing text.
