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 colons.

-d description

The -d flag may be used to provide a description of the resource being shared.

/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

See attributes(5) for descriptions of the following attributes:

mountd(1M), nfsd(1M), share_nfs(1M), shareall(1M), unshare(1M), attributes(5)

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:

example% share -F nfs -o rw=usera:userb /somefs

This behavior is not limited to sharing the root filesystem, but applies to all filesystems.
