The Network Information Service (NIS) was formerly known as Yellow
Pages (yp). Although the name has changed, the functionality of the
service remains the same.
ypmake is a shell script that builds one or more Network Information
Service (NIS) maps (databases) on a master NIS server. If no
arguments are specified, ypmake either creates maps if they do not
already exist or rebuilds maps that are not current. These maps are
constructed from ASCII files. ypmake then executes yppush to notify
slave NIS servers of the change and make the slave servers copy the
updated maps to their machines (see yppush(1M)).
If any maps are supplied on the command line, ypmake creates or
updates those maps only. Permissible names for maps are the filenames
in /etc listed under FILES below. In addition, specific maps can be
named, such as netgroup.byuser or rpc.bynumber.
The make command can be used instead of ypmake (see make(1)). The
Makefile no longer calls the ypmake script but now actually constructs
the maps. All NIS commands have been modified to use the Makefile
instead of ypmake. The Makefile and ypmake can co-exist, but it is
recommended that you consider using the Makefile which is the standard
mechanism for building maps on other vendor's machines.
Both the Makefile and ypmake script use four variables:
DIR=source_directory The directory containing the ASCII
source files from which maps are
constructed. DIR defaults to /etc.
DOM=NIS_domain Causes ypmake to construct maps for the
specified NIS_domain. DOM defaults to
the NIS domain shown by domainname (see
NOPUSH=1 When non-null (null by default), NOPUSH
inhibits copying the new or updated
databases to the slave NIS servers.
Only slave NIS servers in the specified

domain receive yppush notification when
NOPUSH is null.
NOPUSH=2 Does the same thing as NOPUSH=1 and
sends a "clear current map" request to
the local ypserv process.
PWFILE=passwd_file Specifies the full pathname of the ASCII
file that ypmake should use when
building the NIS passwd maps. PWFILE
defaults to $DIR/passwd.
The order of arguments passed to ypmake is unimportant, but the maps
are built or updated in the left-to-right order provided.

Create or rebuild the password databases (both the passwd.byname and
passwd.byuid maps) from /etc/passwd and use yppush to copy the
databases to any slave NIS servers in the default NIS domain:
Create or rebuild the hosts databases from /etc/hosts but do not copy
the databases to any slave NIS servers:
ypmake hosts NOPUSH=1
Create or rebuild the network maps from /nis/sourcefiles/networks and
copy the maps to any slave NIS servers in NIS domain DAE_NIS:
