Here's a script I wrote as an assignment while doing a UNIX course. It's not exactly what you're looking for, but, if you copy and paste it into a script you can see how it runs and then make the necessary changes to show what's required for your homework question:

#!/bin/sh
if [ $# -eq 0 -o $# -gt 1 ]
        then
                echo "Usage: $0 ordinary_file"
                exit 1
fi
if [ -f "$1" ]
        then
               if [ -s "$1" ]
                   then
                          filename="$1"
                          set `ls -iol $filename`
                          echo "Filename: $filename  Size: $1  No. of Hard Links: $3  Owner: $4    Date last modified: $8/$9"
                   else
                          filename="$1"
                          echo "Zero byte file (empty) - deleting file"
                          rm -f $filename
                          exit 2
               fi
        else
               usage "$0: arguement must be an ordinary file"
fi
exit 0
