LAB 45: THE case STATEMENT

Write a script timegreet that will do the following:

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

Convert the following program using case statements:


# The timegreet script by Ellie Quigley

you=$LOGNAME

hour=`date | awk '{print substr($4, 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

Rewrite the lookup script, replacing the if/elif construct with the case command. Add one more menu item:
```
1) Add Entry

2) Delete Entry

3) Update Entry

4) View Entry

5) Exit
```
