   -k --keepdate    Keep the date stamp of output file same as input file. 
   -q --quiet       Quiet mode. Suppress all warning and messages.
   -V --version     Prints version information.

   -c --convmode convmode
                    Set conversion mode.

unix2dos converts plain text files in UNIX format to Windows or MAC format.

Later versions of dos2unix have additional options to add/remove Byte Order Marks (BOM) and handle alternate code pages.

Alternative using sed

sed -i -e 's/\r*$/\r/' file

Examples

Get input from stdin and write output to stdout:

unix2dos

Convert and replace a.txt. Convert and replace b.txt:

unix2dos a.txt b.txt
unix2dos -o a.txt b.txt

Convert and replace a.txt in ASCII conversion mode. Convert and replace b.txt in ISO conversion mode.

unix2dos a.txt -c iso b.txt
unix2dos -c ascii a.txt -c iso b.txt

Convert and replace a.txt while keeping original date stamp:

unix2dos -k a.txt
unix2dos -k -o a.txt

Convert a.txt and write to e.txt:

unix2dos -n a.txt e.txt

Convert a.txt and write to e.txt, keep date stamp of e.txt same as a.txt:

unix2dos -k -n a.txt e.txt

Convert and replace a.txt. Convert b.txt and write to e.txt:

unix2dos a.txt -n b.txt e.txt
unix2dos -o a.txt -n b.txt e.txt

Convert c.txt and write to e.txt. Convert and replace a.txt. Convert and replace b.txt. Convert d.txt and write to f.txt:

unix2dos -n c.txt e.txt -o a.txt b.txt -n d.txt f.txt
