NAME

share − make local resource available for mounting by remote systems

SYNOPSIS

share [ −F FSType ] [ −o specific_options ] [ −d description ] [ pathname [ resourcename ] ]

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.  specific_options as well as the semantics of resourcename are specific to particular distributed file systems.  When invoked with only a file system type, share displays all resources shared by the given file system to the local system.  When invoked with no arguments, share displays all resources shared by the local system. 

OPTIONS

−F FSType Specify the filesystem type. 

−o specific_options The specific_options are used to control access of the shared resource.  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 resourcename. 

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. 

EXAMPLE

This line in /etc/dfs/dfstab will share the /disk file system read-only at boot time. 

share −F nfs −o ro /disk

Note that if a machine is not sharing any file systems, running share has no effect until you either run /etc/init.d/nfs.server start or reboot the system, both of which start up nfsd(1M) server processes. 

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

NOTE

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 or /usr/etc/exportfs.
