Answer 1

If you are running a Java app on a *nix system, and assuming your app has permission to execute the mv command try the following code

String[] shCommand = {"/bin/sh", "-c", "mv somefile newfile"}; 

    // creates a process to run the command in
    Runtime rt = Runtime.getRuntime();
    Process prcs = null;
    try
    {
        // run the command
        prcs = rt.exec(shCommand);
    }
    catch (Exception e)
    {
        console.err("Execute Command Error:");
        e.printStackTrace();
    }

You need to create a Runtime to interface with environment your Java app is running (*nix in this case) and Process to run a process in the environment

EDIT: you may not need the Process part, as I usually use it to have my app wait for command to finish executing or to get the exitcode, so if you don’t need those you may omit the Process part
