EJECT !!!EJECT NAME SYNOPSIS DESCRIPTION COMMAND-LINE OPTIONS LONG OPTIONS EXAMPLES EXIT STATUS NOTES AUTHOR SEE ALSO ---- !!NAME eject - eject removable media !!SYNOPSIS eject -h eject [[-vnrsfq] [[ eject [[-vn] -d eject [[-vn] -a on|off|1|0 [[ eject [[-vn] -c slot [[ eject [[-vn] -t [[ !!DESCRIPTION __Eject__ allows removable media (typically a CD-ROM, floppy disk, tape, or JAZ or ZIP 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. The device corresponding to There are four different methods of ejecting, depending on whether the device is a CD-ROM, SCSI device, removable floppy, or tape. By default eject tries all four methods in order until it succeeds. If the device is currently mounted, it is unmounted before ejecting. !!COMMAND-LINE OPTIONS __-h__ This option causes __eject__ to display a brief description of the command options. __-v__ This makes __eject__ run in verbose mode; more information is displayed about what the command is doing. __-d__ If invoked with this option, __eject__ lists the default device name. __-a on|1|off|0__ This option controls the auto-eject mode, supported by some devices. When enabled, the drive automatically ejects when the device is closed. __-c __ With this option a CD slot can be selected from an ATAPI/IDE CD-ROM changer. Linux 2.0 or higher is required to use this feature. The CD-ROM drive can not 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. __-t__ With this option the drive is given a CD-ROM tray close command. Not all devices support this command. __-n__ With this option the selected device is displayed but no action is performed. __-r__ This option specifies that the drive should be ejected using a CDROM eject command. __-s__ This option specifies that the drive should be ejected using SCSI commands. __-f__ This option specifies that the drive should be ejected using a removable floppy disk eject command. __-q__ This option specifies that the drive should be ejected using a tape drive offline command. !!LONG OPTIONS All options have corresponding long names, as listed below. The long names can be abbreviated as long as they are unique. -h --help -v --verbose -d --default -a --auto -c --changerslot -t --trayclose -n --noop -r --cdrom -s --scsi -f --floppy -q --tape !!EXAMPLES Eject the default device: eject Eject a device or mount point named cdrom: eject cdrom Eject using device name: eject /dev/cdrom Eject using mount point: eject /mnt/cdrom/ Eject 4th IDE device: eject hdd Eject first SCSI device: eject sda Eject using SCSI partition name (e.g. a ZIP drive): eject sda4 Select 5th disc on mult-disc changer: eject -v -c5 /dev/cdrom Turn on auto-eject on a !SoundBlaster CD-ROM drive: eject -a on /dev/sbpcd !!EXIT STATUS Returns 0 if operation was successful, 1 if operation failed or command syntax was not valid. !!NOTES __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 __eject__ does not work, it is most likely a limitation of the kernel driver for the device and not the __eject__ program itself. The -r, -s, -f, and -q 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). __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, __eject__ will follow the link and use the device that it points to. If __eject__ determines that the device can have multiple partitions, it will attempt to unmount all mounted partitions of the device before ejecting. If an unmount fails, the program will not attempt to eject the media. 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. 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. You need appropriate privileges to access the device files. Running as root or setuid root is required to eject some devices (e.g. SCSI devices). The heuristic used to find a device, given a name, is as follows. If the name ends in a trailing slash, it is removed (this is to support filenames generated using shell file name completion). If the name starts with '.' or '/', it tries to open it as a device file or mount point. If that fails, it tries prepending '/dev/', '/mnt/', Creating symbolic links such as /dev/cdrom or /dev/zip is recommended so that __eject__ can determine the appropriate devices using easily remembered names. To save typing you can create a shell alias for the eject options that work for your particular setup. !!AUTHOR __Eject__ was written by Jeff Tranter (tranter@pobox.com) and is released under the conditions of the GNU General Public License.
