Try to look at <a href="http://redis.io/commands/keys" rel="noreferrer"><code>KEYS</code></a> command. <code>KEYS *</code> will list all keys stored in redis.

EDIT: please note the warning at the top of <code>KEYS</code> documentation page:

<blockquote>
 Time complexity: O(N) with N being the number of keys in the database, under the assumption that the key names in the database and the given pattern have limited length.
</blockquote>

UPDATE (V2.8 or greater): <a href="https://redis.io/commands/scan" rel="noreferrer"><code>SCAN</code></a> is a superior alternative to <code>KEYS</code>, in the sense that it does not block the server nor does it consume significant resources. Prefer using it.

Updated for Redis 2.8 and above

As noted in the comments of previous answers to this question, <code>KEYS</code> is a potentially dangerous command since your Redis server will be unavailable to do other operations while it serves it. Another risk with <code>KEYS</code> is that it can consume (dependent on the size of your keyspace) a lot of RAM to prepare the response buffer, thus possibly exhausting your server's memory.

Version 2.8 of Redis had introduced the <a href="http://redis.io/commands/scan" rel="noreferrer">SCAN</a> family of commands that are much more polite and can be used for the same purpose.

The CLI also provides a nice way to work with it:

<pre><code>$ redis-cli --scan --pattern '*'
</code></pre>

It can happen that using redis-cli, you connect to your remote redis-server, and then the command:

<pre><code>KEYS *
</code></pre>

is not showing anything, or better, it shows: 
<code>(empty list or set)</code>

If you are absolutely sure that the Redis server you use is the one you have the data, then maybe your redis-cli is not connecting to the Redis correct database instance.

As it is mentioned in the Redis docs, new connections connect as default to the db 0.

In my case <code>KEYS</code> command was not retrieving results because my database was 1. In order to select the db you want, use <a href="http://redis.io/commands/SELECT">SELECT</a>. 
The db is identified by an integer.

<pre><code>SELECT 1
KEYS *
</code></pre>

I post this info because none of the previous answers was solving my issue.

For the ones that wants a typescript helper (using ioredis)
<pre><code>import Redis from 'ioredis';
import { from, Observable, of } from 'rxjs';
import { first, mergeMap } from 'rxjs/operators';

export function scanKeysFromRedis(redisStore: Redis.Redis, key: string, 
target: number = 0, keys: string[] = []): Observable&lt;string[]&gt; {
 return from(redisStore.scan(target, 'MATCH', key)).pipe(
 first(),
 mergeMap((_keys) =&gt; {
 const _target = Number(_keys[0]);
 if (_target !== 0) {
 return scanKeysFromRedis(redisStore, key, _target, [...keys, ..._keys[1]]);
 }
 return of([...keys, ..._keys[1]]);
 }),
 );
}
</code></pre>
and call it with: scanKeysFromRedis(store, 'hello');

Is there a Redis command for fetching all keys in the database? I have seen some python-redis libraries fetching them. But was wondering if it is possible from redis-client.

Redis command to get all available keys?

是否有Redis命令可以拉取数据库中的所有密钥？我见过一些python-redis库获取它们。但想知道这是否可能从redis-client。
