EJECT(1) User Commands EJECT(1)

NAME

eject - eject media such as CD-ROM and floppy from drive

SYNOPSIS

eject [-dflqt] [ [device | nickname]]

DESCRIPTION

The eject utility is used for those removable media devices that do not
have a manual eject button, or for those that might be locked due to, for
instance, being mounted. The device may be specified by its name or by a
nickname. If no device is specified, the default device is used.

Only devices that support eject under program control respond to this
command.

When eject is used on media that can only be ejected manually, it does
everything except remove the media, including unmounting the file system
if it is mounted. In this case, eject displays a message that the media
can now be manually ejected.

Do not physically eject media from a device that contains mounted file
systems. eject automatically searches for any mounted file systems that
reside on the device, and attempts to umount them prior to ejecting the
media. See mount(8). If the unmount operation fails, eject prints a
warning message and exits. The -f option can be used to specify an eject
even if the device contains mounted partitions.

If you have inserted a floppy diskette, you might need to use volcheck(1)
before ejecting the media to inform the system the floppy's presence.

Pressing the physical media eject button located on some drives' front
panel has the same effect as invoking eject for the respective drive. Not
all drives have this capability.
