Cygwin Dos2Unix Command not found

You should find dos2unix in the category Utils, Base, or Text. It's easiest to use the search function. If the package is not listed at all, try to use a different mirror.

If you installed this package while your cygwin terminal is still open, do a rehash (depends on you shell) or simply start a new terminal.

Additional option, may be helpful for someone:

To install additional packages in windows from command line you can use your cygwin installer (which you've downloaded to install cygwin, it's gui and all the stuff):

$ setup-x86_64.exe -q -P dos2unix
