In computing, line feed is one of control characters in ASCII that is used to move printer or display one line down. Line feed often follows carriage return to indicate a new line. In some envrionments, carriage return is omited and only line feed indicates a new line.

In ASCII, it has a decimal numeral code, 10.

The term derives from the fact that when this control character was sent to early printers, it would physically move down a line, similar to the operation of a typewriter.
