Syntax:
unload jukebox_spec location location
The unload command takes two locations, one of which must be a tape drive, and instructs the jukebox to move a tape out of the drive and into the other location. The second (non-drive) location defaults to the location the tape was loaded from, if that is not available unload looks for the lowest numbered empty slot. (see the "Locations" section for information on location syntax)
