Loot

#loot is an extended command used to open an unlocked container on the floor. Containers in the inventory are opened by applying them.

You cannot loot locked containers. You have to first open the lock by either applying some unlocking tools at them, or breaking the lock with a weapon (using the #force comman) or kicking the locked container. However, kicking may destroy the contents: you will hear a muffled shatter if that happens. Forcing the lock with a weapon also has a chance of breaking your weapon.

Sometimes looting a container may trigger a trap, such as a poison needle.

Loot is also the general name by which the stuff that you have found is called. It is often used in a context like "In addition to the wand, I found lots of nice loot from the Castle." Useless loot is called junk.
