Unix2Dos

The Dos2unix package includes utilities dos2unix and unix2dos to convert plain
text files in DOS or Mac format to Unix format and vice versa.

In DOS/Windows text files a line break, also known as newline, is a combination
of two characters: a Carriage Return (CR) followed by a Line Feed (LF). In Unix
text files a line break is a single character: the Line Feed (LF). In Mac text
files, prior to Mac OS X, a line break was single Carriage Return (CR)
character. Nowadays Mac OS uses Unix style (LF) line breaks.

Besides line breaks Dos2unix can also convert the encoding of files. A few DOS
code pages can be converted to Unix Latin-1. And Windows Unicode (UTF-16) files
can be converted to Unix Unicode (UTF-8) files.
