what does `PS` command mean in vscode terminal on windows?

Question

I am trying to reproduce this post.

this is a classic hello world in java, with additional package app;

package app;

public class App {
    public static void main(String[] args) throws Exception {
        System.out.println("Hello Java");
    }
}

when I click "run" btn inside this code, vscode output this bunch

Hello Java
PS C:\Lecture_java\Lecture001\Hello> & 'C:\Users\ubuntu\.vscode\extensions\vscjava.vscode-java-debug-0.23.0\scripts\launcher.bat' 'C:\Program Files\Java\jdk-13.0.1\bin\java' '-Dfile.encoding=UTF-8' '-cp' 'C:\Lecture_java\Lecture001\Hello\bin' 'app.App'

first line is the output of my java code.

I guess the second line is the log that how vscode acturally process the java file.

question

what does PS command mean?

the PS command only work inside vscode terminal. running PS command in cmd.exe gives this error.

'PS' is not recognized as an internal or external command, operable program or batch file.

Answer 1

The PS indicates it is a powershell prompt.

Powershell code cannot be run inside a command.exe prompt.
