<p>在<a href="https://stackoverflow.com/questions/483460/how-to-mount-from-command-line-like-the-nautilus-does">looking at this thread</a>讲述了ubuntu如何处理nautilus之后，我找到了一些建议，并决定通过shell命令访问udisk。</p>
<p>您需要的是大容量存储设备类。把设备文件给它。ie:/dev/sdb
然后，您可以执行d.mount（）和d.mount_点，以获取它的安装位置。</p>
<p>之后也是一个类，用于查找许多相同的USB设备，以控制安装、卸载和弹出一大串具有相同标签的设备。
（如果运行时没有参数，则它会将此应用于所有SD设备。对于“自动挂载所有内容”脚本来说可能很方便</p>
