redis-cli how to AUTH using password and issue a command?

When no password is set, we can issue for instance;

>> redis-cli keys *

or

>> redis-cli config set requirepass "aaaaaa"

However, after we have have issued the latter, the first no longer works and results in:

>> redis-cli keys *
  (error) NOAUTH Authentication required.

We need to authenticate. Sure.

>> redis-cli AUTH aaaaaa
   OK
>> redis-cli keys *
   (error) NOAUTH Authentication required.

How do we authenticate and then able to execute a command?

Is this not possible? Heredocs only?

I've tried:

>> redis-cli AUTH aaaaaa && config set requirepass "aaaaaa"

But did not work. Also semicolon after aaaaaa. Not work.

How?

My use-case is Redis in a docker exec cli.
As I'm learning Redis I didn't wanted to AUTH all the time. So for testing I'm resetting the need for a password.

 echo 'AUTH redis\nCONFIG SET requirepass ""' | redis-cli

On a restart of the container the password is set again.

Assign your password to REDISCLI_AUTH env var (and export it). The docs say:

NOTE: For security reasons, provide the password to redis-cli
automatically via the REDISCLI_AUTH environment variable.

This seems to work:

redis-cli <<- 'EOF'
        AUTH aaaaaa
        config set requirepass aaaaaa
EOF

You can pass the -a argument for authenticating the redis-cli command like this:

redis-cli -h 127.0.0.1 -p 6379 -a mypassword keys *

The AUTH commands only last for the duration of the tcp connection. Each new invocation of redis-cli creates a new connection, thus you have to authenticate at each invocation.

It is possible to execute several redis commands on one invocation of redis-cli: they must be separated by \n

Thus this would work:

echo -e 'AUTH aaaaaa\nkeys *' | redis-cli

Note: The other answer also provides a way to pass arguments separated by \n to redis-cli
