The
utility processes the contents of the
group(5),
passwd(5),
hosts(5)
and
netid(5)
files into the format used to generate the
netid.byname
NIS
map.
This map is used to hold credential information for both users
and hosts in an operating system independent format.
The
utility checks for duplicate occurrences of netids and filters
them out.
The
utility prints its results on the standard output.
It is usually called
only by
/var/yp/Makefile
when rebuilding the
NIS
maps.
OPTIONS
The
utility supports the following options:
-q
Normally,
prints a warning message when it encounters a duplicate netid.
This flag turns on 'quiet' mode, allowing the warnings to be
suppressed.
Other error messages may still be generated.
-g group_file
Specify the location of the group information
file.
The compiled-in default is
/etc/group
-p passwd_file
Specify the location of the passwd information
file.
The compiled-in default is
/etc/passwd
-h hosts_file
Specify the location of the hosts database
file.
The compiled-in default is
/etc/hosts
-n netid_file
Specify the location of the netid information
file.
The compiled-in default is
/etc/netid
Note that no error is generated if the netid database cannot be
found.
The netid database is not likely to be present on most systems
until
Secure RPC
support is added to
Fx .
-d domain
By default, the
utility uses the system domainname when generating netid records.
If
the system domainname is not set, the domain must be specified on the
command line with the
-d
flag.
If the domainname is set, the
-d
flag may be used to override it.
