--list List of Redis database operations under LUnix

First, you need to understand the concepts of stacks and queues first:

Stack advanced after: The Bullets on the analogy magazine, the last bullet bullets first use, drywall brick, from behind

Queue FIFO: line up for rice, first come first served

To create a list:

Add to Left: (Stack form Add)

# Output: " 5 " " 4 " " 3 " " 2 " " 1 "

Right add: (added as queue)

Rpush List 1 2 3 4 5#  output:"1"2)  "2"3)  " 3 "4)  "4"5)  "5"

To view the list:

Lrange list 0-1   #  Index View  0 (first bit)-1 (last)

View Length:

Llen list   #  returns a number

View the specified element: (index)

# The   4th element is viewed here from the 0th bit

To delete an element:

Lpop list  #  Delete rpop List # from the left to    Delete from the right

Delete the specified number of elements:

Lrem List 3 (number) 5(Element)#  means to remove 3 ' 5 ' from the top of this element #  If it is-3 means to remove 3 ' 5 ' from the bottom of the element
