Full Discussion: Confusion with CRLF (wint) and LF (unix) as end of line seperators

It is a historic design issue error in some early Operating systems, many of which precede Microsoft. Early printer-terminals were either real Teletypes or similar emulations of a typewriter.
Before proper printer drivers you used to print a file by copying it straight to the printer port down a serial cable. It needed the carriage-return character to print correctly.
Later printers had a dipswitch to optionally tell the printer to treat a linefeed as a carriage-return-line-feed.
The first PC which I came across with text files with carriage-return-line-feed as a text file record terminator was running Digital Research CP/M . The contemporary forerunners of modern unix did not have this issue.

In the modern world it still matters. You are best advised to use unix-format text files on unix and MSDOS format text files on Microsoft O/S because much software expects this.
