Apt-cyg

Installing a package using apt-cyg
If you have already installed cygwin and are looking for a convenient way to install additional software from the command line, the apt-cyg tool may be just what you need. The apt-cyg utility provides a commandline package installation facility which cooperates with the cygwin setup program and uses the same repository. The apt-cyg utility provides the following command line options:

apt-cyg install foo bar   # install packages foo and bar apt-cyg remove foo bar    # remove packages foo and bar apt-cyg update            # refresh setup.ini apt-cyg show              # list installed packages apt-cyg find foobar       # list packages that have names that match the pattern foobar apt-cyg describe foo bar  # describe packages matching patterns foo and bar apt-cyg packageof foobar  # find packages containing file named foobar

Dependencies
The apt-cyg utility cannot be used to install cygwin from scratch. Before apt-cyg can be used, the [bash], [wget], [tar], g[awk] and [bzip2] packages must be installed.
