If you ever find yourself in the situation of having to replace CRLF (Win) or CR (Mac) with LF (Unix), remember that the regex/C escape codes are \n=LF and \r=CR (and for good measure, \f = FF).
A sed string that will do the correct replacement is 's/\r\n|\r/\n/g'. On OS X, you can use it in conjunction with
pbpaste, which will paste to stdout the content of the OS X clipboard (this hint from macoshints).
