using different database at redis command prompt

Question

dThe following works as expected. But how do I insert the data into forth database instead of default "0" from command prompt?

# echo -n "testing" | /home/shantanu/redis-2.4.2/src/redis-cli -x set my_pass
OK

# echo -n "testing" | /home/shantanu/redis-2.4.2/src/redis-cli -x select 4; set my_pass
(error) ERR wrong number of arguments for 'select' command

Solution 1

Just use the -n argument to choose DB number. It available since Redis 2.4.2.

echo -n "testing" | redis-cli -n 4 -x set my_pass

or

redis-cli -n 4 set my_pass testing

Solution 2

Launch the CLI by issuing command:

redis-cli

Then use the following command:

select <db number>

For example:

select 4

Thanks - I wish they'd add this to the documentation - redis.io/commands/select

Thanks for this. In case anyone is using Python in addition to redis-cli, you simply add db=4 to the connection parameters when you initialize a new redis client. Extended example: POOL = redis.ConnectionPool(host='10.0.0.1', port=6379, db=4) which is also referenced at the answer here
