When computers came out, storage was expensive. Some people decided that
they did not need two characters for end-of-line. The UNIX people decided
they could use <Line Feed> only for end-of-line. The Apple people

This means that if you try to move a file from one system to another, you
have line-break problems. The Vim editor automatically recognizes the
different file formats and handles things properly behind your back.

The three names that Vim uses are:

USING THE MAC FORMAT
On Unix, <LF> is used to break a line. It's not unusual to have a <CR>
On Unix, <NL> is used to break a line. It's not unusual to have a <CR>
character halfway a line. Incidentally, this happens quite often in Vi (and
Vim) scripts.
On the Macintosh, where <CR> is the line break character, it's possible to

The result is that it's not possible to be 100% sure whether a file
containing both <CR> and <LF> characters is a Mac or a Unix file. Therefore,
containing both <CR> and <NL> characters is a Mac or a Unix file. Therefore,
Vim assumes that on Unix you probably won't edit a Mac file, and doesn't check
for this type of file. To check for this format anyway, add "mac" to
