crlf /ker'l*f/, sometimes /kru'l*f/ or /C-R-L-F/ n.

(often capitalized as `CRLF') A carriage return (CR, ASCII 0001101) followed by a line feed (LF, ASCII 0001010). More loosely, whatever it takes to get you from the end of one line of text to the beginning of the next line. See newline, terpri. Under Unix influence this usage has become less common (Unix uses a bare line feed as its `CRLF').
