The end of a line. Also called "EOL" (end-of-line), "newline," and "hard return," a line break code is inserted into the computer when the Enter key is pressed, For command lines, pressing Enter means execute the command. For text, it signifies the end of the paragraph, and subsequent text goes to the next line.
In word processing, line break codes, along with indent and other layout codes, are normally hidden on screen; however, a special, expanded mode may reveal them. Some text editors display line breaks as symbols (see below).
The Codes Are Different
In Windows and DOS, the line break code is a carriage return followed by a line feed (CR/LF). In the Unix/Linux/Mac world, the code is only the LF. In older Macs, the code was a single CR; however, current Macs also support old Mac documents. If line breaks are not converted between platforms, text displays and prints improperly. See soft return.
Support for All Platforms
This RazorSQL database browser provides line break conversion for all plaforms. The "r" is the CR, and the "n" is the LF (newline).
Look for 0A and 0D
The LF and CR are the 11th an 13th ASCII characters, which in hexadecimal (this chart) are 0A and 0D (see ASCII chart
Depending on the text editor, line breaks may show up as different symbols.
