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 tool at them, or breaking the lock with a weapon (using the #force command) or kicking the locked container. However, kicking (or forcing the lock with a blunt weapon) may destroy the contents: you will hear a muffled shatter if any glass object breaks, and a muffled cracking in the case of eggs. Forcing the lock with an edged weapon has a chance of breaking your weapon.

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

The loot command can also be used to remove the saddle from a saddled monster.

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.
