Hello.

In this situation, I probably wouldn't even bother with getopts.

If you only want to install 1, 2, or 3 packages (thus assuming that the ONLY action that the script is to perform is to install packages) you could do the following:

Code:
#!/bin/sh

if [ "$#" -gt 3 ]; then
  echo "More than 3 arguments entered" && exit 1
fi

pkgs=""

if [ "$#" -eq 0 ]; then
  echo "Please enter a space seperated list of packages"
  read pkgs
fi

if [ -z "$pkgs" ]; then
  # user must have supplied some arguments
  for file in "$@"
  do
    # then install $file as you want
  done
else
  for file in "$pkgs"
  do
   # then install $file as you want
  done
fi

exit 0

Now... I haven't checked this out - just wrote it on the fly. But you get the idea......

DESCRIPTION

	 rinse is a simple script which is designed to be able to install
	a minimal working installation of an RPM-based distribution into
	a directory.

	 The tool is analogous to the standard Debian GNU/Linux debootstrap
	utility.

USAGE

	 To use this script you will need to be root.  This is required
	to mount /proc, run chroot, and more.

	 Basic usage is as simple as:

	  rinse --distribution fedora-core-6 --directory /tmp/test

	 This will download the required RPM files and unpack them into
	a minimal installation of Fedora Core 6.

	 To see which RPM files would be downloaded, without actually
	performing an installation or downloading anything, then you
	may run the following:

	  rinse --distribution fedora-core-6 --print-uris

TODO

	 Short of supporting more distributions or architectures there aren't
	really any outstanding issues.
