EJECT(1)                    General Commands Manual                   EJECT(1)

       eject - eject media device from drive

       eject [ -dfnq ] [ device | nickname ]

       This command is not available on Sun 386i systems.

       eject is used for those removable media devices that do not have a man-
       ual eject button.  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

       It is not recommended to physically eject media  from  a  device  which
       contains  mounted  filesystems.   eject  automatically searches for any
       mounted filesystems which reside on the device and attempts  to  umount
       them prior to ejecting the media (see mount(8)).  If the unmount opera-
       tion fails, eject prints a warning message and exits.  The -f flag  may
       be  used to specify an eject even if the device contains mounted parti-

       eject can also display its default device and a list of nicknames.

       -d          Display the name of the default device to be ejected.

       -f          Force the device to eject even if it is busy.

       -n          Display the nickname to device name translation table.

       -q          Query to see if the media is present.

       device      Specify which device to eject, by the name as it appears in
                   the directory /dev.

       nickname    Specify  which device to eject, by its nickname as known to
                   this command.

       /dev/rsr0           raw files
       /dev/sr0            block files

       fd(4S), sr(4S), mount(8)

       eject returns the following exit codes:

              0      If the operation was successful or, with the  -q  option,
                     if the media is in the drive.

              1      If the operation was unsuccessful or, with the -q option,
                     if the media is not in the drive.

              2      If invalid flags were specified.

              3      If an ioctl() request failed.

       A short help message is printed if an unknown  flag  is  specified.   A
       diagnostic  is  printed if the device name cannot be opened or does not
       support eject.

       Device Busy: An attempt was made to eject a device that has  a  mounted
       filesystem.   A warning message is printed when doing a forced eject of
       a mounted device. However, if a device is doing a  format,  "eject  -f"
       will not have any effect.

       There should be a way to change the default on a per-user basis.
