Mounting a Disk Image File (DMG) from the Terminal: 

(this works the same for ISO and IMG files as well)

hdiutil attach /path/to/your/diskimage.dmg

When the .dmg is mounted, a message will display something like this (not that hditul will try to use the dmg filename as the directory name it creates in /Volumes):

$ hdiutil attach diskimage.dmg                                                                                           9:49
Checksumming Gesamte Disk (Apple_HFS : 0)…

/dev/disk2          	                               	/Volumes/diskimage

Unmounting a DMG from the Terminal is just as easy:

hditul detach /Volumes/diskimage
 
or (CAUTION: where /dev/disk2 is the one hdiutil created this during mounting the DMG file)
 
hditul detach /dev/disk2

If you are not sure anymore what was mounted where, then try using this to see a list:

hdiutil info

This will output something like this (depending on your situation of course):

 

framework       : 623.100.1
driver          : 623.100.1
