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......

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a    Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
