DECR

The DECR command in Redis decreases the integer value of a key by 1. If the key does not exist, it is initialized to 0 before performing the decrement. If the key contains a value that is not an integer, Redis returns an error. This command is useful in counters and for tracking state changes in a simple, atomic way.
