share - make local resource available for mounting by remote systems
FSType] specific_options] description] [pathname]
The command exports, or makes a resource available for mounting, through a remote file system of type FSType.
If the option is omitted, the first file system type listed in 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, displays all shared file systems.
recognizes the following options:
Specify the file system type.
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:
is shared read/write to all clients. This is also the default behavior.
pathname read-mostly if option is not provided. Read-mostly means read-write to those clients specified and read-only for
all other systems. If a option is provided, pathname is shared read/write only to the listed clients. No other systems
can access pathname.
is shared read-only to all clients.
is shared read-only only to the listed clients. No other systems can access pathname.
The flag may be used to provide a description of the resource being shared.
Old terminology (export)
File system sharing used to be called on HP-UX, and was used for exporting file systems. With the new share NFS model, the command
replaces exportfs(1M) or
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) com-
mand. 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 commands are invoked multiple times on the same file system, the last invocation supersedes the previous; the options set by the last
command replace the old options. For example, if read-only permission was previously given to on use the following command to also give
read-only permission to on
This behavior is not limited to sharing the root file system, but applies to all file systems.
