Comparing two months

Hi all,

Using shell script and awk statements, I manage to get the month and year of the Patch Bundle installed on the system. Now I have to compare month and year of Patch Bundle installed to the Patch Bundle which is desired on the workstation. I am able to do easily comparison of year but not of month. Can anyone suggest how to do this???

In short I have to accomplish:
if [ "march" greater than "november" ];
then
echo "jjjjjjjj"
else
echo "iiiiiiii"
fi

Thanx for your cooperation and help
Regards,
Pankaj

Use a case statement to convert month to numeric form.
