How to give the permission?
sudo
or gksudo
to act on them as root.
chown user:group
to change ownership.
chmod 'permission in octal'
to change permission type for user:group:everyone
su user
to switch to an appropriate user.
I frequently put things in /opt that belong to multiple users, but are pretty portable and not in repos. I don't think saying 'use sudo' is necessarily right for '/opt' specific questions.
