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.
Specify the filesystem type.
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:
pathname is shared read/write to all clients. This is also the default behavior.
pathname is shared read/write only to the listed clients. No other systems can access pathname.
pathname is shared read-only to all clients.
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.
The -d flag may be used to provide a description of the resource being shared.
This line will share the /disk file system read-only at boot time.
share -F nfs -o ro /disk
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
list of share commands to be executed at boot time
list of file system types, NFS by default
system record of shared file systems
See attributes(5) for descriptions of the following attributes:
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.
