   1. Provide a comment section at the top of the script, with your name , the date, and the purpose of this program.

   2. Convert the following program using case statements:

        # The timegreet script by Ellie Quigley  you=$LOGNAME hour=`date  awk '{print substr(, 1, 2)}'` print "The time is: $(date)" if (( hour > 0 && $hour < 12 )) then      print "Good morning, $you!" elif (( hour == 12 )) then      print "Lunch time!" elif (( hour > 12 && $hour < 16 )) then      print "Good afternoon, $you!" else      print "Good night, $you!" fi
