Windows and Unix systems use different methods toidentify end-of-line information in text files. Windows 9x and NT use a carriage return/linefeed pair (CR/LF), whilst Unix only uses the LF character. DOS2UNIX.EXE and UNIX2DOS.EXE are small Win32 console-mode file conversion utilities. DOS2UNIX.EXE converts Windows text files to Unix format, by stripping any CR or end-of-file (Ctrl-Z) characters from the data. UNIX2DOS.EXE inserts a CR character when it encounters an LF character, converting the data to Windows format.
