mknetid —
a NIS filter program
  
    | mknetid | [ -q] [-ddomain] [-ggroupfile] [-hhostfile] [-mnetidfile] [-ppasswdfile] | 
mknetid is used to create a map named
  netid.byname. The map consists of information from
  passwd(5),
  group(5) and
  hosts(5) eventually concatenated
  with a netid(5) file.
The options are as follows:
  - -ddomain
- NIS domain to use instead of the default domain.
- -ggroupfile
- Alternate group(5) file.
      Default is /etc/group.
- -hhostfile
- Alternate hosts(5) file.
      Default is /etc/hosts.
- -mnetidfile
- Alternate netid(5) file.
      Default is /etc/netid.
- -ppasswdfile
- Alternate passwd(5) file.
      Default is /etc/passwd.
- -q
- Keep quiet about multiple occurrences of a uid; ignore all but the
    first.
