How to find and delete files under a directory not looking at subdirectories in Solaris

How to find and delete files under a directory not looking at subdirectories in Solaris?

In GNU linux there is a –maxdepth option to ‘find’ command which can be used to prevent looking at subdirectories but it is not available for Sun solaris.

I use the below approach, here I want to remove all files except from NOTSENT and RESEND and which are older than 1 day.

find . -type d \( -name NOTSENT -o -name RESEND \)  -prune -o -type f -mtime +1 -print -exec rm -rf {} \;

try 'man find' on solaris for more details.
