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  manu-
     ally,  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(1M).
     If the unmount operation fails, eject prints a warning  mes-
     sage  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 sys-
     tem 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  capabil-
     ity.

OPTIONS
     The following options are supported:

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