NAME
     exportfs - export and unexport directories to NFS clients

SYNOPSIS
     /usr/etc/exportfs [ -aituvfR ] [ -o options ] [ directory ]

DESCRIPTION
     exportfs makes a local directory (or file) available for mounting over
     the network by NFS clients.  It is normally invoked at boot time by the
     /etc/init.d/network script, and uses information contained in the
     /etc/exports file to export a directory (which must be specified as a
     full pathname).  The superuser can run exportfs at any time to alter the
     list or characteristics of exported directories.  Directories that are
     currently exported  are listed in the file /etc/xtab.

     With no options or arguments, exportfs prints out the list of directories
     currently exported.

OPTIONS
     -a   All.  Export all directories listed in /etc/exports, or if -u is
          specified, unexport all of the currently exported directories.

     -t   Normally exportfs will attempt to find out a real pathname for the
          exported entry. In some situations, e.g. a filesystem on which an
          exported entry resides becomes unavailable or a user actually intend
          to export a symlink to preserve logical namespace setup, the path
          name to real path name translation can be suppressed by using this
          option.

     -v   Verbose.  Print each directory as it is exported or unexported.

     -u   Unexport the indicated directories.

     -i   Ignore the options in /etc/exports.  Normally, exportfs consults
          /etc/exports for the options associated with the exported directory.

     -f   Remove entry from /etc/xtab even if it cannot be unexported.

     -R   Starting with 6.5.28 exportfs does not enumerate the entries in the
          netgroups at the export time which means any hostnames which cannot
          be resolved will not be reported. By using this option it is
          possible to return to the pre-6.5.28 behaviour to check the entries
          in the netgroup.

     -o options
          Specify a comma-separated list of optional characteristics for the
          directory being exported.  options are described in exports(4).

FILES
     /etc/exports      static export information


     /etc/xtab         current state of exported directories
     /etc/netgroup

SEE ALSO
     exports(4), netgroup(4), showmount(1M).

WARNINGS
     You cannot export a directory that is either a parent- or a sub-directory
     of one that is currently exported and within the same filesystem.  It
     would be illegal, for example, to export both /usr and /usr/local if both
     directories resided in the same disk partition.

     Extremely long export lists (hundreds of hosts or netgroups for a single
     exported directory) may cause mount requests for that exported directory
     to time out.

     In the Trusted IRIX environment filesystems should not be exported to
     non-Trusted clients. Trix clients should be explicitly defined when
     exporting, (see exports(4)).

     When exporting a symbolic link, the actual exported entry will be the
     real path to a directory or a file to which the symbolic link points to.
     If export of a symbolic link is required, e.g. to create a logical
     hierarchy, use -t option. Note that if a symbolic link is exported by
     using -t option then a directory or a file to which it points to must
     also be exported otherwise access to such entry will be denied.
