Date Format in UNIX

Hi Guys,

Need some help. I want to use the date command in Unix and having this below format as an output. the month should be in FIRST 3 LETTERS & ALL CAPS. And the DAY should be in two digits format

DESIRED OUTPUT:

09-JUN-11

I tried to use this command below but still it does NOT give the desired output.

root>date '+%e-%b-%y'
 9-Jun-11

Thanks in advance.

Br,
Pinpe

date '+%d-%b-%y' | tr '[a-z]' '[A-Z]'

same one, cleaned.
