Convert to case statements from if/elif
Hello, I wrote the case on code but it mistakes. I am not sure.

If/elif code:
Code:
#!/bin/ksh
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

Change Case code:

Code:
#!/bin/ksh

you=$LOGNAME
hour=`date | awk '{print substr($4, 1, 2)}'`
print "The time is: $(date)"

case $hour in

(hour > 0 && $hour < 12 ) echo "Good morning, $you!";;
(hour == 12 ) echo "Lunch time!";;
(hour > 12 && $hour < 16 ) echo "Good afternoon, $you!;;
echo "Good night, $you!";;

esac

Did I mistake this the case?

Thanks,
