I was having a problem with the script that creates my installer for macosx not working and I discovered it was because it was creating a folder called /Volumes/myinstaller 1 instead of /Volumes/myinstaller. While investigating this issue I found that I have a hidden volume called /Volumes/myinstaller with all the relevant files inside but I cannot rmdir the directory because it contains many layers of files. Is there someway to eject a hidden volume through the terminal or to see the hidden volume in the finder?

Heh heh rm -r worked. Oh well duh.

In general, to dismount volumes, hidden or otherwise, you want to use diskutil unmount (or hdiutil detach) and not umount, thanks to OSX's diskarbitrationd:

$ sudo umount /Volumes/NAME/
Password:
umount: unmount(/Volumes/NAME): Resource busy
$ diskutil unmount /Volumes/NAME/
Volume NAME  on disk3s1 unmounted

It is also possible to use diskutil to return information about mounted volumes in a structured way (a plist) for scripting. See the man pages for diskutil and hdiutil for more info.
