SELECT command, you can write the most commonly used select method. As follows:
Copy Code code as follows:
Dir | Select Name,lastwritetime
This command displays the name and last modified date of the files and subfolders in the current folder.
where
The where command is used for filtering, which can be abbreviated to?, using the following example:
Copy Code code as follows:
Dir |? {$_.mode–like "d*"} | Select Name,lastwritetime
This command can dis

Some of the common operational commands in Linux are described later, using these commands to quickly locate the problem and solve the problem. Today,-top commands from the most common start.
Introduction to command meaning

This article is for you to understand 2 questions
What data types in Java are available for storing data?
How is the data type in Java converted?
In the previous article we learned how to use variables, like this to store an integer int age=10; , you can write a line in the development tool such code int age=10.5; will find the development tool error, because the data type in the variable is also not easy to use.Data type

and the other on the Myfloat value type. There are two reasons to use a pointer recipient. First, avoid copying values in each method call (more efficient if the value type is a large struct). Second, the method can modify the value that the receiver points to.
Try to modify the definition of Abs, while the scale method uses Vertex instead of *vertex as the receiver.
The scale method has no effect when V is Vertex. ' Scale ' modifies ' V '. When V is a value (not a pointer), the method sees a c
