SHARE(1M)SHARE(1M)NAMEshare - make local resource available for mounting by remote systems
SYNOPSISshare [-p] [-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-d description
The -d flag may be used to provide a description of the resource
being shared.
-F FSType
Specify the filesystem type.
-o specific_options
The specific_options are used to control access of the shared
resource. (See share_nfs(1M) for the 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]...
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.
Separate multiple options with commas. Separate multiple operands
for an option with colons. See EXAMPLES.
-p
Causes the share operation to persist across reboots.
EXAMPLES
Example 1 Sharing a Read-Only Filesystem
This line will share the /disk file system read-only at boot time.
share-F nfs -o ro /disk
Example 2 Invoking Multiple Options
The following command shares the filesystem /export/manuals, with mem‐
bers of the netgroup having read-only access and users on the specified
host having read-write access.
share-F nfs -o ro=netgroup_name,rw=host1:host2:host3 /export/manuals
FILES
/etc/dfs/dfstab
List of share commands to be executed at boot time. Note that you
can invoke share from a command line and use the -p option,
described above, as an alternative to editing this file.
/etc/dfs/fstypes
List of file system types; NFS is the default.
/etc/dfs/sharetab
System record of shared file systems.

attributes(5)NOTES
Export (old terminology): file system sharing used to be called export‐
ing on SunOS 4.x, so the share command used to be invoked as
exportfs(1B) or /usr/sbin/exportfs.
If share commands are invoked multiple times on the same filesystem,
the last share invocation supersedes the previous—the options set by
the last share command replace the old options. For example, if read-
write permission was given to usera on /somefs, then to give read-write
permission also to userb on /somefs:
example% share-F nfs -o rw=usera:userb /somefs
This behavior is not limited to sharing the root filesystem, but
applies to all filesystems.
