share(1M)
NAME
share − make local resource available for mounting by remote systems
SYNOPSIS
share [ −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
−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:
rwpathname 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.
ropathname 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.
−d description The −d flag may be used to provide a description of the resource being shared.
EXAMPLES
This line will share the /disk file system read-only at boot time.
share −F nfs −o ro /disk
FILES
/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

NOTES
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.
