How can you retrieve all elements of a list in Redis?

In Redis, you can use the LRANGE command to retrieve all elements in a list.

The syntax of the LRANGE command is as follows:

LRANGE key start stop

In this case, key is the key name of the list, and start and stop are the respective starting and ending positions (index values) of the elements to be obtained. To get all the elements in the list, you can set start to 0 and stop to -1.

For example, suppose there is a list named mylist that contains the following elements:

1) "apple"
2) "banana"
3) "orange"
4) "grape"

You can use the following command to retrieve all elements in this list:

LRANGE mylist 0 -1

After executing the command, the following results will be returned:

1) "apple"
2) "banana"
3) "orange"
4) "grape"

In this way, all the elements in the list were successfully acquired.
