How do I format a date in a KornShell (ksh) script to DD-MON-YYYY?
I have tried the following:
date '+%d-%h-%Y'
It returns 04-Nov-2009 I need for the Nov to be NOV (all caps). Can this be done with the date utility?

This is what finally worked on unix(solaris).
date '+%d-%h-%Y' | tr [:lower:] [:upper:]
returned: 04-NOV-2009

The ^ character forces uppercase in the GNU coreutils date (at least, it does in version 6.9.92.4 of coreutils):
$ date '+%d-%^h-%Y'
04-NOV-2009
Unfortunately, ^ is not POSIX standard for date, so you'll probably have to resort to a second command such as the tr suggested by @martin clayton, if you aren't on a GNU system.

You could uppercase it yourself if caret uppercase is not supported in your environment:
date '+%d-%h-%Y' | tr 'a-z' 'A-Z'
