share [-F FSType] [-o specific_options] [-d description] [pathname]
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.
-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.
-d description
The -d flag may be used to provide a description of the resource being shared.
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 members 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
/etc/dfs/dfstab
list of share commands to be executed at boot time
/etc/dfs/fstypes
list of file system types, NFS by default
/etc/dfs/sharetab
system record of shared file systems

Export (old terminology): file system sharing used to be called exporting 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:
This behavior is not limited to sharing the root filesystem, but applies to all filesystems.
