+.SH NAME
+eject \- eject removable media
+.SH SYNOPSIS
+.B eject
+[options]
+.IR device | mountpoint
+.SH DESCRIPTION
+.B eject
+allows removable media (typically a CD-ROM, floppy disk, tape, JAZ, ZIP or USB
+disk) to be ejected under software control.  The command can also control some
+multi-disc CD-ROM changers, the auto-eject feature supported by some devices,
+and close the disc tray of some CD-ROM drives.
+.PP
+The device corresponding to \fIdevice\fP or \fImountpoint\fP is ejected.  If no
+name is specified, the default name \fB/dev/cdrom\fR is used.  The device may be
+addressed by device name (e.g., 'sda'), device path (e.g., '/dev/sda'),
+UUID=\fIuuid\fR or LABEL=\fIlabel\fR tags.
+.PP
+There are four different methods of ejecting, depending on whether the device
+is a CD-ROM, SCSI device, removable floppy, or tape.  By default \fBeject\fR tries
+all four methods in order until it succeeds.
+.PP
+If a device partition is specified, the whole-disk device is used.
+.PP
+If the device or a device partition is currently mounted, it is unmounted
+before ejecting.  The eject is processed on exclusive open block device
+file descriptor if \fB\-\-no\-unmount\fP or \fB\-\-force\fP are not specified.
+
+.SH OPTIONS
+.TP
+.BR \-a , " \-\-auto on" | off
+This option controls the auto-eject mode, supported by some devices.  When
+enabled, the drive automatically ejects when the device is closed.
+.TP
+.BR \-c , " \-\-changerslot " \fIslot
+With this option a CD slot can be selected from an ATAPI/IDE CD-ROM changer.
+The CD-ROM drive cannot be in use (mounted data CD or playing a music CD) for
+a change request to work. Please also note that the first slot of the changer
+is referred to as 0, not 1.
+.TP
+.BR \-d , " \-\-default"
+List the default device name.
+.TP
+.BR \-F , " \-\-force"
+Force eject, don't check device type, don't open device with exclusive lock.
+The successful result may be false positive on non hot-pluggable devices.
+.TP
+.BR \-f , " \-\-floppy"
+This option specifies that the drive should be ejected using a removable floppy
+disk eject command.
+.TP
+.BR \-h , " \-\-help"
+Display help text and exit.
+.TP
+.BR \-i , " \-\-manualeject on" | off
+This option controls locking of the hardware eject button.  When enabled, the
+drive will not be ejected when the button is pressed.  This is useful when you
+are carrying a laptop in a bag or case and don't want it to eject if the button
+is inadvertently pressed.
+.TP
+.BR \-M , " \-\-no\-partitions\-unmount"
+The option tells eject to not try to unmount other partitions on partitioned
+devices.  If another partition is still mounted, the program will not attempt
+to eject the media.  It will attempt to unmount only the device or mountpoint
+given on the command line.
+.TP
+.BR \-m , " \-\-no\-unmount"
+The option tells eject to not try to unmount at all.  If this option is not
+specified than
+.B eject
+opens the device with O_EXCL flag to be sure that the device is not used (since
+v2.35).
+.TP
+.BR \-n , " \-\-noop"
+With this option the selected device is displayed but no action is performed.
+.TP
+.BR \-p , " \-\-proc"
+This option allows you to use /proc/mounts instead /etc/mtab.  It also passes the
+\fB\-n\fR option to \fBumount\fR(8).
+.TP
+.BR \-q , " \-\-tape"
+This option specifies that the drive should be ejected using a tape drive
+offline command.
+.TP
+.BR \-r , " \-\-cdrom"
+This option specifies that the drive should be ejected using a CDROM eject
+command.
+.TP
+.BR \-s , " \-\-scsi"
+This option specifies that the drive should be ejected using SCSI commands.
+.TP
+.BR \-T , " \-\-traytoggle"
+With this option the drive is given a CD-ROM tray close command if it's opened,
+and a CD-ROM tray eject command if it's closed.  Not all devices support this
+command, because it uses the above CD-ROM tray close command.
+.TP
+.BR \-t , " \-\-trayclose"
+With this option the drive is given a CD-ROM tray close command.  Not all
+devices support this command.
+.TP
+.BR \-V , " \-\-version"
+Display version information and exit.
+.TP
+.BR \-v , " \-\-verbose"
+Run in verbose mode; more information is displayed about what the command is
+doing.
+.TP
+.BR \-X , " \-\-listspeed"
+With this option the CD-ROM drive will be probed to detect the available
+speeds.  The output is a list of speeds which can be used as an argument of the
+\fB\-x\fR option.  This only works with Linux 2.6.13 or higher, on previous versions
+solely the maximum speed will be reported.  Also note that some drives may not
+correctly report the speed and therefore this option does not work with them.
+.TP
+.BR \-x , " \-\-cdspeed " \fIspeed
+With this option the drive is given a CD-ROM select speed command.  The
+.I speed
+argument is a number indicating the desired speed (e.g., 8 for 8X speed), or 0
+for maximum data rate.  Not all devices support this command and you can only
+specify speeds that the drive is capable of.  Every time the media is changed
+this option is cleared.  This option can be used alone, or with the
+\fB\-t\fR and \fB\-c\fR options.
+.SH EXIT STATUS
+Returns 0 if operation was successful, 1 if operation failed or command syntax
+was not valid.
+.SH NOTES
+.B eject
+only works with devices that support one or more of the four methods of
+ejecting.  This includes most CD-ROM drives (IDE, SCSI, and proprietary), some
+SCSI tape drives, JAZ drives, ZIP drives (parallel port, SCSI, and IDE
+versions), and LS120 removable floppies.  Users have also reported success with
+floppy drives on Sun SPARC and Apple Macintosh systems.  If
+.B eject
+does not work, it is most likely a limitation of the kernel driver for the
+device and not the
+.B eject
+program itself.
+.PP
+The \fB\-r\fR, \fB\-s\fR, \fB\-f\fR, and \fB\-q\fR options allow controlling
+which methods are used to
+eject.  More than one method can be specified.  If none of these options are
+specified, it tries all four (this works fine in most cases).
+.PP
+.B eject
+may not always be able to determine if the device is mounted (e.g., if it has
+several names).  If the device name is a symbolic link,
+.B eject
+will follow the link and use the device that it points to.
+.PP
+If
+.B eject
+determines that the device can have multiple partitions, it will attempt to
+unmount all mounted partitions of the device before ejecting (see also
+\fB--no-partitions-unmount\fR).  If an unmount fails, the program will not
+attempt to eject the media.
+.PP
+You can eject an audio CD.  Some CD-ROM drives will refuse to open the tray if
+the drive is empty.  Some devices do not support the tray close command.
+.PP
+If the auto-eject feature is enabled, then the drive will always be ejected
+after running this command.  Not all Linux kernel CD-ROM drivers support the
+auto-eject mode.  There is no way to find out the state of the auto-eject mode.
+.PP
+You need appropriate privileges to access the device files.  Running as root is
+required to eject some devices (e.g., SCSI devices).
