dfstab

dfstab(4)							   File Formats 							 dfstab(4)

NAME

       dfstab - file containing commands for sharing resources across a network

DESCRIPTION

       dfstab  resides	in  directory /etc/dfs and contains commands for sharing resources across a network. dfstab gives a system administrator a
       uniform method of controlling the automatic sharing of local resources.

       Each line of the dfstab file consists of a share(1M) command. The dfstab file can be read by the  shell	to  share  all	resources.  System
       administrators can also prepare their own shell scripts to execute particular lines from dfstab.

       The contents of dfstab put into effect when the command shown below is run. See svcadm(1M).

	 /usr/sbin/svcadm enable network/nfs/server

SEE ALSO

       share(1M), shareall(1M), sharemgr(1M), svcadm(1M)

NOTES

       Do  not modify this file directly. This file is reconstructed and only maintained for backwards compatibility. Configuration lines could be
       lost.

       Use the sharemgr(1M) command for all share management.
