B4J Question Shutdown Computer

[ykucuk]

Hello,

i need restart & shutdown computer for all platforms (windows, mac, Linux)

i tried with Jshell but i cant success. Below code always return Exit code: 1

Dim shl As Shell

shl.Initialize("shl", "shutdown.exe",  Array As String("-s -t 0"))

shl.WorkingDirectory = "C:\Windows\System32\"

shl.Run(10000) 'set a timeout of 10 seconds

I found that code on GitHub. is it possible convert this code to b4j

public static void shutdown() throws RuntimeException, IOException {
   String shutdownCommand;
   String operatingSystem = System.getProperty("os.name");

   if ("Linux".equals(operatingSystem) || "Mac OS X".equals(operatingSystem)) {
       shutdownCommand = "shutdown -h now";
   }
   else if ("Windows".equals(operatingSystem)) {
       shutdownCommand = "shutdown.exe -s -t 0";
   }
   else {
       throw new RuntimeException("Unsupported operating system.");
   }

   Runtime.getRuntime().exec(shutdownCommand);
   System.exit(0);
}

Try using PowerShell:

Restart:

PowerShell.exe Restart-Computer

Shut Down:

PowerShell.exe Stop-Computer

Thank you. It works well with Windows.

Do you have a solution for Linux/Mac systems?

shl.Initialize("shl", "shutdown.exe", Array As String("-s -t 0"))

The parameters need to be broken out, else jshell and the command line only see one parameter

Array As String(“-s”, “-t”, “0”)

Note: don’t copy paste my code sample since my phone is using different quote characters.
Note2: You need root for shutdown to work
Note3: corrected array. Each parameter and their values must be separate.
