MDN / CRLF

CR and LF are control characters or bytecode that can be used to mark a line break in a text file.

  • CR = Carriage Return (\r, 0x0D in hexadecimal, 13 in decimal) — moves the cursor to the beginning of the line without advancing to the next line.

  • LF = Line Feed (\n, 0x0A in hexadecimal, 10 in decimal) — moves the cursor down to the next line without returning to the beginning of the line.

A CR immediately followed by a LF (CRLF, \r\n, or 0x0D0A) moves the cursor to the beginning of the line and then down to the next line.
