 Name

    ypmake - rebuild network information service (NIS) databases

 Syntax

    /etc/yp/ypmake [ map ]

 Description

    ypmake is used to build the network services information database. If
    make(CP) is on the system, the file makefile in the directory /etc/yp is
    used by make(CP) to build the network information service database.  If
    make(CP) is not on the system, then ypmake will create the database
    unconditionally.  With no arguments, ypmake creates dbm(NS) databases for
    any NIS maps that are out-of-date and then executes yppush(NADM) to
    notify the slave databases that there has been a change.

    If you supply a map on the command line, ypmake will update that map
    only.  Typing ypmake passwd will create and yppush the password database
    (assuming it is out-of-date).  Likewise, ypmake hosts and ypmake networks
    will create and yppush the host and network files, /etc/hosts and
    /etc/networks, respectively.

    There are three special variables used by ypmake:  DIR, which gives the
    directory of the source files; NOPUSH, which when non-null inhibits doing
    a yppush of the new database files; and DOM, used to construct a domain
    other than the master's default domain.  The default for DIR is /etc and
    the default for NOPUSH is the null string.

    Refer to ypfiles(NF) and ypserv(NADM) for an overview of the network in-
    formation service, and ypmapxlate(NF) for file format.
