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
systems. With the new share NFS model, the share command replaces exportfs (1M) or
/usr/sbin/exportfs.
To support compatiblity with scripts that still invoke the exportfs command using the access= option, the
share command will not fail when the access option is used and the syntax matches the usage of
exportfs (1M) from a release of HP-UX that does not support the share (1M) command. Attempts to use the
access option with new share options, (i.e. sec=), may result in the access option begin rejected by the
share command. It is highly recommended that the access option not be used with the share command.
Instead, use the ro= and rw= option to achieve the desired access restrictions. This support of the access=
option will be removed in a future release of HP-UX.
If
share commands are invoked multiple times on the same file system, the last share invocation
supersedes the previous; the options set by the last share command replace the old options. For exam-
ple, if read-only permission was previously given to usera on somefs, use the following share com-
mand 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.
