NAME
share - make local resource available for mounting by remote systems
SYNOPSIS
/usr/sbin/share
[-F FSType][
-o specific_options][-d description][pathname]
DESCRIPTION
The
share command exports, or makes a resource available for mounting, through a remote file system of
type FSType.
If the option
-F FSType is omitted, the first file system type listed in
/etc/dfs/fstypes
is used as
default.
For a description of NFS specific options, see share_nfs(1M).
pathname is the pathname of the directory to be shared. When invoked with no arguments,
share
displays all shared file systems.
Options
share recognizes the following options:
-F FStype Specify the file system type.
-o specific_options
The specific_options are used to control access of the shared resource. (See share_nfs(1M) for
NFS specific options.) They may be any of the following:
rw pathname is shared read/write to all clients. This is also the default behavior.
rw=client[:client] ...
Share the pathname read-mostly if sec= option is not provided. Read-mostly means
read-write to those clients specified and read-only for all other systems. If a sec=
option
is provided, pathname is shared read/write only to the listed clients. No other systems
can access pathname.
ro pathname is shared read-only to all clients.
ro=client[:client] ...
pathname is shared read-only only to the listed clients. No other systems can access
pathname.
-d description
The -d flag may be used to provide a description of the resource being shared.
WARNINGS
Old terminology (export)
File system sharing used to be called exporting on HP-UX, and exportfs was used for exporting file sys-
tems. With the new share NFS model, the share command replaces exportfs(1M) or
/usr/sbin/exportfs
.
If
share commands are invoked multiple times on the same file system, the last share
invocation super-
sedes the previous; the options set by the last
share command replace the old options. For example, if
read-only permission was previously given to usera on somefs, use the following share command to
also give read-only permission to userb on somefs:
share -F nfs -o ro=usera:userb /somefs
This behavior is not limited to sharing the root file system, but applies to all file systems.
EXAMPLES
The following command wll share the disk file system read-only.
share -F nfs -o ro /disk
