You should use share at the command line prompt when you want
to share a resource for a brief period of time, or on an irregular basis.
To share NFS resources in this way, use the following command:
share [-F nfs] [-o specific-options] [-d description] pathname
See the share(1Mnfs) manual page for details, and ``Examples: sharing resources'' for an illustration of the share command in use.
If you enter the -d option, the description is stored in your sharetab file. However, clients will not see the description displayed when they use the dfshares command to list the resources shared on your system.
The resource is shared with read/write permissions by default.
You would share a resource this way only if you are in a trusting environment.
