How to delete redis keys?

To delete Redis keys, you can use the DEL command followed by the key or keys you want to delete. You can delete multiple keys at once by passing multiple key names as arguments to the DEL command.

Here are the steps to delete Redis keys:

1. Connect to your Redis server using a command-line interface or a Redis client.
2. Use the DEL command followed by the key or keys you want to delete. For example, to delete a single key named "mykey", you can use the following command: DEL mykey
3. If you want to delete multiple keys, you can pass multiple key names as arguments to the DEL command. For example, to delete keys "key1", "key2", and "key3", you can use the following command: DEL key1 key2 key3
4. After executing the DEL command, Redis will remove the specified keys from the database.

Please note that deleting keys in Redis is irreversible, so make sure you double-check before deleting any keys.
