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.

A:
In Terminal try:
umount -a(All the filesystems described via getfsent(3) are unmounted.)umount -A(All the currently mounted filesystems except the root unmounted.)
Fore more information see man umount.
Update:
Seems like you can also use this:
diskutil unmountDisk /dev/disk*
Didn't test it, though. If it doesn't work, try to use "unmount" instead of "unmountDisk".
Oh, I also found the eject argument (instead of unmountDisk). That might also be of interest.
Update 2:
diskutil eject /dev/* seems what you are looking for (see comments).

Why not? Any error messages? If so, please post them here. Also did you try the "-A" option (capital A).

I tried umount -a, and a finder window opened, but that was it. I'll have to try the other commands tonight when I'm back where my external hard drives are.

`diskutils eject /path/to/volume` worked
