On some jukeoboxes, tapes can come in and out of jukeboxes via some form of "mailbox slot" or port where tapes can be entered into the jukebox without opening and closing the door. The "import" and "export" commands are used to do this. You can tell if the jukebox you have supports this by whether it lists and "port" locations in the list output.
By default, "export" will use port 0 to remove the named tape from the jukebox. You can also export listing a specific drive or slot rather than a tape name. An example of using export to unload a tape by name is:
% juke
> set jukebox xyz
> import "newtapename"
> list
default drive: d0
default slot: s0
default port: p0
