源代码：

int result = rootUtil.execute(getShellPath(updateBinaryFile) + " 2 1 " + getShellPath(mZipPath), callback);

    public synchronized int execute(String command, LineCallback callback) {
        if (mShell == null) {
            throw new IllegalStateException("shell is not running");
        }

        mCallback = callback;
        mCommandRunning = true;
        mShell.addCommand(command, 0, mStdoutListener);
        waitForCommandFinished();

        return mLastExitCode;
    }
    
        public synchronized void addCommand(String[] commands, int code,
                                            OnCommandLineListener onCommandLineListener) {
            this.commands.add(new Command(commands, code, null, onCommandLineListener));
            runNextCommand();
        }

参数代入后的命令是：

/data/data/de.robv.android.xposed.installer/cache/update-binary 2 1 /storage/emulated/0/Android/data/de.robv.android.xposed.installer/cache/downloads/framework/xposed-v89-sdk24-arm64.zip

可以看到执行的就是上面那条命令，求解，这个命令是啥？
