Redis is a key-value database. It is similar to memcached but the dataset is not volatile and other datatypes (such as lists and sets) are natively supported.
redis-cli provides a simple command-line interface to a Redis server.
See redis-doc for more information on the commands Redis accepts.
redis-cli was written by Salvatore Sanfilippo.
