restrict a user to certain command

Hi all,

I am using Sun OS 5.10. I am new to Unix.

Is there some way to restrict a specific user to certain command say "/usr/bin/more" ??
for example: I want that user1 can execute more command & user2 can't.

Can we somehow edit .profile file in the home directory of user to achieve this ??
OR
is there some other way ??

Pls help.

Thanks N Regards,
VIKAS
