reject is used to exit a removable device
The reject command is used to exit a removable device. If the device is hooked, the reject command unloads the device before exiting.
eject allows removable media (typically cd-ROM, floppy disk, tape, or JAZ and zip disks) to be ejected under software control. This command can also control some multi-disk CD-ROM controllers, control the auto-eject function supported by some devices, and control the closing of some CD-ROM drive disk trays. The device corresponding to name will pop up. Name can be the device file or its mount point, the full path, or omitting the previous/dev or/mnt device file name. If no name is specified, cdrom is used by default.
There are four different ways to eject, depending on whether the device is a CD-ROM, SCSI device, removable floppy disk, or tape. The default pop-up tries all four methods in turn until it succeeds. If the device is currently mounted, uninstall it before ejecting it.
