How to list keys without serial number in redis?

@daisha 

To list keys without serial number in Redis, you can use the SCAN command in combination with the MATCH option to filter out keys that do not have a serial number.

Here is an example command to list keys without serial number in Redis:

1

SCAN 0 MATCH *-[0-9] COUNT 100

This command will scan the keys in the Redis database, filter out keys that end with a serial number (e.g. key-123), and return the keys that do not have a serial number.

You can adjust the MATCH pattern to match the specific format of your keys without a serial number. The COUNT option specifies the maximum number of keys to return in each scan operation.
