Java invokes the shell command under Linux and returns the result as a stream __web

This article writes that Java invokes the Linux shell command and returns the result as a stream.

The following is directly on the code, the code is annotated.

Very plain and easy to understand.

Import Java.io.BufferedReader;
Import java.io.IOException;
Import Java.io.InputStreamReader;

public class Main
{public
	static void Main (string[] args)
	{
		
		//Get the related Runtime run object of the Java process
		Runtime runtime = Runtime.getruntime ();

		Try
		{
			///Use the Exec () method to execute the shell command Ls-al/root and return a process object that is a subprocess
			//ps: Here are examples of the simplest shell commands.
			Process Process = Runtime.exec ("Ls-al/root"); 

			BufferedReader bufferreader = new BufferedReader (
					new InputStreamReader (Process.getinputstream ()));

			StringBuffer StringBuffer = new StringBuffer ();

			String temp = null;

			while (temp = Bufferreader.readline ())!= null)
			{
					stringbuffer.append (temp);
					
					Stringbuffer.append ("\ n");
			}
			
			System.out.println (StringBuffer);

		}
		catch (IOException e)
		{
			e.printstacktrace ();
		}
	}
}
