examine

Syntax: examine <container>
Syntax: examine <corpse>

Examine is short for ‘Look container’ followed by ‘Look
in container’ which will show the name of the container and
what is in it. The same holds true for examine corpse, since
a corpse is basically a container.

When used without an argument examine will show you details of the current
room, such as decor, toughness and security levels.
