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.
