share - make local resource available for mounting by remote systems
share [-p] [-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 sys- tems.
-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.
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 speci- fied 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. 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.

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.
