Shutdown Remote Computer in Java- Cannot initiate shutdown but no errors

问题

I am learning about the Runtime class in java, and am testing the use of command line instructions in it. I am trying to remotely shutdown a computer using Runtime.getRuntime().exec(...); When I run this, there are no errors, but the specified machine does not shut down. I don't know why.

Code:

import java.io.IOException;

class shutdownVirus {
    public static void main(String[] args) throws IOException {
        Runtime.getRuntime().exec("shutdown -m \\\\T12-LEOPARDIJ -s -t 10");
    }
}

Any help will be greatly appreciated. Thanks

回答1:

Try

Runtime.getRuntime().exec("shutdown -s");

Edited part:

Use this.

shutdown /s /m <Computer_Name> To shutdown a remote PC

回答2:

It probably does not work because the VM you are running the Java class with is started from a user that does not have shutdown rights. The process would inherit these access restrictions and therefore no be allowed to shut down.

Arguably thats a good thing..
