Get the key type:

TYPE <key>

Then retrieve it's value based on its type.

GET <key>

LRANGE <key> 0 -1

SMEMBERS <key>

ZRANGE <key> 0 -1 WITHSCORES

HGETALL <key>

Check the number of keys in each Redis database:

INFO keyspace

# Keyspace
db0:keys=450,expires=12,avg_ttl=500000
db1:keys=200,expires=5,avg_ttl=300000

db0 has 450 keys, db1 has 200 keys. Some keys have expiration times.

If Redis has multiple databases (default: db0), to work with db0

SELECT 0

To switch to db1:

SELECT 1

DEL <key>

To delete all keys in the currently-selected database:

FLUSHDB

To delete all keys in Redis:

FLUSHALL
