 NAME
      mount, umount - mount and unmount an CDFS file systems

 SYNOPSIS
      /usr/sbin/mount [-l] [-p|-v]

      /usr/sbin/mount -a [-F cdfs] [-eQ]

      /usr/sbin/mount [-F cdfs] [-eQrV] [-o specific_options]
		{special|directory}

      /usr/sbin/mount [-F cdfs] [-eQrV] [-o specific_options]
		special directory

      /usr/sbin/umount -a [-F cdfs] [-v]

      /usr/sbin/umount [-v] [-V] {special|directory}

 DESCRIPTION
      The mount command mounts file systems.  Only a superuser can mount
      file systems.  Other users can use mount to list mounted file systems.

      The mount command attaches special, a removable file system, to
      directory, a directory on the file tree.	directory, which must
      already exist, will become the name of the root of the newly mounted
      file system.  special and directory must be given as absolute path
      names.  If either special or directory is omitted, mount attempts to
      determine the missing value from an entry in the /etc/fstab file.
      mount can be invoked on any removable file system, except /.

      If mount is invoked without any arguments, it lists all of the mounted
      file systems from the file system mount table, /etc/mnttab.

      The umount command unmounts mounted file systems.	 Only a superuser
      can unmount file systems.

    Options (mount)
      mount recognizes the following options:

	   -a	       Attempt to mount all file systems described in
		       /etc/fstab.  All optional fields in /etc/fstab must
		       be included and supported.  If -F cdfs is specified,
		       all CDFS file systems in /etc/fstab are mounted.	 If
		       noauto is specified in an entry's option list, this
		       entry is skipped.  File systems are not necessarily
		       mounted in the order listed in /etc/fstab.

	   -e	       Verbose mode.  Write a message to standard output
		       indicating which file system is being mounted.

	   -F cdfs     Specify the CDFS file system type (see fstyp(1M)).

	   -l	       Limit actions to local file systems only.

	   -o specific_options
		       Specify options specific to the CDFS file system
		       type.  specific_options is a list of comma separated
		       suboptions and/or keyword/attribute pairs intended
		       for the CDFS specific module of the command.

		       The following specific_options are valid on CDFS file
		       systems.

		       cdcase	   Suppress the display of version numbers.
				   Show and match file names as lower case.

		       defaults	   Use all default options.  When given,
				   this must be the only option specified.

		       ro	   Mount read-only (default).

		       suid	   Allow set-user-ID execution (default).

		       nosuid	   Do not allow set-user-ID execution.

	   -p	       Report the list of mounted file systems in the
		       /etc/fstab format.

	   -Q	       Prevent the display of error messages resulting from
		       an attempt to mount already mounted file systems.

	   -r	       Mount the specified file system as read-only.  This
		       option is equivalent to the -o ro specific_option.
		       For CDFS file systems this is a default option.

	   -v	       Report the regular output with file system type and
		       flags; however, directory and special fields are
		       reversed.

	   -V	       Echo the completed command line, but performs no
		       other action.  The command line is generated by
		       incorporating the user-specified options and other
		       information derived from /etc/fstab.  This option
		       allows the user to verify the command line.

    Options (umount)
      umount recognizes the following options:

	   -a	       Attempt to unmount all file systems described in
		       /etc/mnttab.  All optional fields in /etc/mnttab must
		       be included and supported.  If -F cdfs is specified,

		       all CDFS file systems in /etc/mnttab are unmounted.
		       File systems are not necessarily unmounted in the
		       order listed in /etc/mnttab.

	   -F cdfs     Specify the CDFS file system type (see fstyp(1M)).

	   -v	       Verbose mode.  Write a message to standard output
		       indicating which file system is being unmounted.

	   -V	       Echo the completed command line, but performs no
		       other action.  The command line is generated by
		       incorporating the user-specified options and other
		       information derived from /etc/fstab.  This option
		       allows the user to verify the command line.

 DIAGNOSTICS
      umount complains if the special file is not mounted or if it is busy.
      The file system is busy if it contains an open file or some logged-in
      user's working directory.

 EXAMPLES
      Mount a local CDFS disk:

	   mount -F cdfs /dev/dsk/c0t0d4 /cdrom

      Unmount a local CDFS disk:

	   umount /dev/dsk/c0t0d4

 WARNINGS
      Some degree of validation is done on the file system, however, it is
      generally unwise to mount file systems that are defective, corrupt, or
      of unknown origin.

 NOTES
      Additional CD-ROM formats are supported using PFS (Portable File
      System) utilities.  See pfs(4) for more details.
