redis-cli is the command-line interface for Redis, an in-memory data structure store used as database, cache, and message broker. It provides interactive and scripted access to Redis servers.
In interactive mode (no command specified), redis-cli presents a prompt for entering commands. Commands follow Redis protocol: command name followed by arguments, with responses displayed immediately.
Common operations include key-value storage (GET, SET, DEL), lists (LPUSH, RPOP), sets (SADD, SMEMBERS), hashes (HSET, HGET), and pub/sub messaging (PUBLISH, SUBSCRIBE).
The tool supports cluster mode, sentinel connections, and various debugging and monitoring features for Redis administration.

-h host

Server hostname (default: 127.0.0.1)

Server port (default: 6379)

Password for AUTH command

Database number to select

Connect using Redis URI (redis://...)

Repeat command count times

Interval between repeats (seconds)

List keys using SCAN instead of KEYS

Transfer raw Redis protocol from stdin

Transfer RDB dump from server to file

Execute cluster commands

Monitor latency continuously

Print rolling stats

SET key value: Store a value
GET key: Retrieve a value
DEL key: Delete a key
KEYS pattern: Find keys matching pattern
EXPIRE key seconds: Set key expiration
TTL key: Get remaining time to live
FLUSHDB: Delete all keys in current database
INFO: Server information and statistics
PING: Test connection

Using KEYS \* on production servers with large datasets can block the server. Use SCAN instead for iterating keys in production.
Passwords passed with -a appear in process listings and shell history. Use REDIS_AUTH environment variable or interactive AUTH for sensitive environments.
Redis databases are numbered 0-15 by default. Use -n to select a database or SELECT command interactively.
