.Sh NAME
.Nm mknetid
.Nd generate a YP map of group and domain memberships
.Sh SYNOPSIS
.Nm mknetid
.Bk -words
.Op Fl q
.Op Fl d Ar domain
.Op Fl g Ar groupfile
.Op Fl h Ar hostfile
.Op Fl m Ar netidfile
.Op Fl P Ar master.passwdfile
.Op Fl p Ar passwdfile
.Ek
.Sh DESCRIPTION
The
.Nm
utility combines information from the
.Xr passwd 5 ,
.Xr group 5 ,
.Xr hosts 5 ,
and
.Xr netid 5
files, printing it in
.Xr netid 5
format to the standard output.
If the
.Xr passwd 5
file is not available, the
.Xr master.passwd 5
file is used instead.
The
.Xr netid 5
file is optional and does not need to exist.
.Pp
The most common application is to pass the output to
.Xr makedbm 8
in order to create a
.Pa netid.byname
map for the
.Xr yp 8
subsystem.
.Pp
The options are as follows:
.Bl -tag -width Ds
.It Fl d Ar domain
Use
.Ar domain
instead of the default
.Xr domainname 1 .
.It Fl g Ar groupfile
Use
.Ar groupfile
instead of
.Pa /etc/group .
.It Fl h Ar hostfile
Use
.Ar hostfile
instead of
.Pa /etc/hosts .
.It Fl m Ar netidfile
Use
.Ar netidfile
instead of
.Pa /etc/netid .
.It Fl P Ar master.passwdfile
Use
.Ar master.passwdfile
instead of
.Pa /etc/master.passwd .
.It Fl p Ar passwdfile
Use
.Ar passwdfile
instead of
.Pa /etc/passwd .
.It Fl q
