Java从ProcessBuilder获取PID

Question

我用ProcessBuilder启动一个进程，但我需要获取PID。 （进程ID）

                    List<String> bel = Arrays.asList(befehl.split(","));
                    ProcessBuilder bu2 = new ProcessBuilder(bel);
                    bu2.directory(new File("/home/cloud/" + modi + "/" + name));
                    Process p = bu2.start();

我怎么能指出这个？

Answer 1

type Props = XOR<{ children: React.ReactNode; title: string; subtitle: string; subtleSubtitle?: boolean }, { children: React.ReactNode; title?: string }>

myFunc({ subtitle: "some text" }) // Error
myFunc({ subtitle: "some text", children: <p>hi</p> }) // Error
myFunc({ title: "cool", subtitle: "some text", children: <p>hi</p> }) // Works
