dos2unix is a utility that replaces the line endings in a file from DOS/Windows CRLF (0D 0A) to Unix LF (0A).

unix2dos does the reverse, replacing LF with CRLF.

By default, a named file is converted in-place, but stdio redirection can be used instead, and an -n switch can be used to specify separate in and out files. Options also exist for limited conversion among character sets. (TODO: Document these here.)

A lot of files can be converted at once using Find#dos2unix.2Funix2dos.
