flip - unix2dos & dos2unix - Newline conversion between Unix and MS-DOS ASCII files

ASCII text files can contain different forms of newlines, depending on which operating system is being used. Converting between these formats is often necessary if you use several operating systems. The flip program will convert the newlines to any format given in the table below:

Operating System		Newline Character(s)
Microsoft Windows / MS-DOS		0Dh 0Ah
Apple Macintosh OS 9 and earlier		0Dh
Unix (e.g., Linux), also Apple OS X and higher		0Ah

The flip command will convert between each of these types of newline formats. Here is the usage statement for the program:

Usage: flip [-t|-u|-d|-m] filename[s]
   Converts ASCII files between Unix, MS-DOS/Windows, or Macintosh newline formats

   Options:
      -u  =  convert file(s) to Unix newline format (newline)
      -d  =  convert file(s) to MS-DOS/Windows newline format (linefeed + newline)
      -m  =  convert file(s) to Macintosh newline format (linefeed)
      -t  =  display current file type, no file modifications
