有没有办法从命令行弹出所有外部硬盘驱动器? (OS X) [英] is there a way to eject all external hard drives from the command line? (OS X)

问题描述

是否可以从命令行弹出OS X计算机上所有已安装的硬盘驱动器卷?如果我可以将其包装在Shell脚本中，则Applescript可以.

Is there a way to eject all the mounted hard drive volumes on an OS X computer from the command line? Applescript is OK if I can wrap that in a shell script.

推荐答案

在终端中尝试:

• umount -a (已卸载通过getfsent(3)描述的所有文件系统.)
• umount -A (当前所有已安装的文件系统，但未卸载根).

• umount -a (All the filesystems described via getfsent(3) are unmounted.)
• umount -A (All the currently mounted filesystems except the root unmounted.)

有关更多信息，请参见man umount.

Fore more information see man umount.

似乎您也可以使用此功能:

Seems like you can also use this:

diskutil unmountDisk /dev/disk*

虽然没有测试.如果它不起作用，请尝试使用"unmount"代替"unmountDisk".

Didn't test it, though. If it doesn't work, try to use "unmount" instead of "unmountDisk".

哦，我还找到了eject参数(而不是unmountDisk).这可能也很有趣.

Oh, I also found the eject argument (instead of unmountDisk). That might also be of interest.

diskutil eject /dev/*似乎是您想要的东西(请参阅评论).

diskutil eject /dev/* seems what you are looking for (see comments).
