vim Converting text files from DOS to UNIX with vi Using VIm's fileformat
Example
When Vim opens a file with <CR><NL> line endings (common on MSDOS based operating systems, also called CRLF) it will set fileformat to dos, you can check what with:
:set fileformat?
fileformat=dos
Or just
:set ff?
fileformat=dos
To convert it to <NL> line endings (common on most UNIX based operating systems, also called LF) you can change the fileformat setting and Vim will change the buffer.
:set ff=unix
