.Sh NAME
.Nm mknetid
.Nd "generate netid map data"
.Sh SYNOPSIS
.Nm
.Op Fl q
.Op Fl g Ar group_file
.Op Fl p Ar passwd_file
.Op Fl h Ar hosts_file
.Op Fl n Ar netid_file
.Op Fl d Ar domain
.Sh DESCRIPTION
.Nm Mknetid
processes the contents of the
.Xr group 5 ,
.Xr passwd 5 ,
.Xr hosts 5
and
.Xr netid 5
files into the format used to generate the
.Pa netid.byname
.Tn NIS
map.
This map is used to hold credential information for both users
and hosts in an operating system independent format.
.Pp
The
.Nm
command checks for duplicate occurrences of netids and filters
them out.
.Pp
The
.Nm
command prints its results on the standard output.
It is usually called
only by
.Pa /var/yp/Makefile
when rebuilding the
.Tn NIS
maps.
.Sh OPTIONS
The
.Nm
command supports the following options:
.Bl -tag -width indent
.It Fl q
Normally,
.Nm
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.
.It Fl g Ar group_file
Specify the location of the group information
file.
The compiled-in default is
.Pa /etc/group .
.It Fl p Ar passwd_file
Specify the location of the passwd information
file.
The compiled-in default is
.Pa /etc/passwd .
.It Fl h Ar hosts_file
Specify the location of the hosts database
file.
The compiled-in default is
.Pa /etc/hosts .
.It Fl n Ar netid_file
Specify the location of the netid information
file.
The compiled-in default is
.Pa /etc/netid .
Note that no error is generated if the netid database can't be
found.
The netid database is not likely to be present on most systems
until
.Tn Secure RPC
support is added to
.Dx .
.It Fl d Ar domain
By default, the
.Nm
command 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
.Fl d
flag.
If the domainname is set, the
.Fl d
flag may be used to override it.

.Sh FILES
