The unload command is used to get a tape from a a drive back into a slot. The unload command will accept a jukebox specifier, a drive location, and a slot location, and will take the tape from the drive and put it away. The jukebox and drive will revert to the set defaults if they are not specified, the slot to move the tape to defaults to the slot from which it was loaded. Like all juke commands this can be done with the juke interactive mode, or from the command line.
