NAME

       dossrv, 9660srv, a:, b:, c:, eject - DOS and ISO9660 file systems

SYNOPSIS

       dossrv [ -v ] [ -s ] [ -f file ] [ service ]

       9660srv [ -v ] [ -s ] [ -f file ] [ service ]

       a:

       c:

       eject [ n ]

DESCRIPTION

       Dossrv  is a file server that interprets DOS file systems.  A single instance of dossrv can provide access to multiple DOS disks simultane-
       ously.

       Dossrv posts a file descriptor named service (default dos) in the /srv directory.  To access the DOS file system on  a  device,	use  mount
       with  the  spec	argument  (see bind(1)) the name of the file holding raw DOS file system, typically the disk.  If spec is undefined in the
       mount, dossrv will use file as the default name for the device holding the DOS system.

       Normally dossrv creates a pipe to act as the communications channel between itself and its clients.  The -s flag instructs  dossrv  to  use
       its  standard input and output instead.	The kernels use this if they are booting from a DOS disk.  This flag also prevents the creation of
       an explicit service file in /srv.

       The -v flag causes verbose output for debugging.

       The shell script a: contains

	      unmount /n/a: >[2] /dev/null
	      mount -c /srv/dos /n/a: /dev/fd0disk

       and is therefore a shorthand for mounting a floppy disk in drive A.  The scripts b: and c: are similar.

       9660srv is identical to dossrv in specification, except that it interprets ISO9660 CD-ROM file systems instead of DOS file systems.

       If the floppy drive has an ejection motor, eject will spit out the floppy from drive n, default 0.

EXAMPLE

       Mount a floppy disk with a DOS file system on it.

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(1M). 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 pres-
       ence.

OPTIONS

       The following options are supported:

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

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

       -l    Display paths and nicknames of ejectable devices.

       -q    Query to see if the media is present.

       -t    Issues the drive a CD-ROM tray close command.

	     Not all devices support this command.

OPERANDS

       The following operands are supported:

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

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

		   Volume label or device type (for example, cdrom or floppy0) can be used as a nickname.

EXAMPLES

       Example 1 Ejecting Media

       The following example ejects media by its volume label:

	 example> eject 'My Pictures'

       Example 2 Ejecting a Floppy Disk

       The following example ejects a floppy disk from the first floppy drive:

	 example> eject floppy0

EXIT STATUS

       The following exit codes are returned:

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

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

       2    Invalid options were specified.

       3    An ioctl() request failed.

       4    Manually ejectable media is now okay to remove.

FILES

       /dev/diskette0	 default diskette file

       /dev/sr0 	 default CD-ROM file (deprecated)
