Step 1: Install Redis
- Make sure you have Redis installed on your system. If not, you can download and install it from the official Redis website.
Step 2: Start Redis Server
- Start the Redis server by running the following command in the terminal:
redis-server
Step 3: Connect to Redis
- Open a new terminal window and connect to the Redis server using the following command:
redis-cli
Step 4: Create a List
- To create a new list in Redis, use the following command:
LPUSH mylist "Hello"
- This command will create a list named "mylist" with the value "Hello" at the beginning.
Step 5: Add Elements to the List
- You can add more elements to the list using the following command:
RPUSH mylist "World"
- This command will add the value "World" to the end of the list.
Step 6: Retrieve Elements from the List
- To retrieve elements from the list, you can use the following command:
LRANGE mylist 0 -1
- This command will return all the elements in the list.
Step 7: Remove Elements from the List
- If you want to remove elements from the list, you can use the following command:
LPOP mylist
- This command will remove and return the first element from the list.
Step 8: Check the Length of the List
- To check the length of the list, use the following command:
LLEN mylist
- This command will return the number of elements in the list.
