Windows uses a pair of characters - both a CR and an LF.Older Macintosh systems use CR (carriage return, another ASCII control character).

CR and LF are usually represented in scripts, search strings, or source code by r and n, or by the octal numbers 015 and 012. The FF (form feed) control character made the printer advance to the next page. CR made the printing head go back to column 1, and LF made the printer advance a line by feeding paper. In the old printer and teletype days, machines interpreted control characters and produced an effect on output. They cannot use standard, common characters to represent the line end, because those could appear in normal text, so they use special, nonprinting characters - but each operating system uses different ones: The newline problemĮvery operating system uses a special character (or sequence of characters) to signify the end of a line of text. This article explains why we have these problems and shows ways to solve them. However, converting such files from Windows or Mac OS results in formatting differences for the newline characters and character encoding. The easiest way to transfer data between systems is by using plain text files or common formats like comma-separated value (CSV) files. This kind of import process requires some conversions to solve file format differences otherwise, it would be impossible to share data, or file contents would be imported incorrectly. However, the need to get data from Windows, MS-DOS, or old Macintosh systems is all too common.
Life would be a lot easier if we could live in a Linux-only world and if applications never required data from other sources.
