hpux 10.20 - vipw (1)

 NAME
      vipw - edit the password file

 SYNOPSIS
      vipw

 DESCRIPTION
      vipw edits the password file while setting the appropriate locks, and
      does any necessary processing after the password file is unlocked.  If
      the password file is already being edited, you will be told to try
      again later.  The vi editor is used unless the environment variable
      EDITOR indicates an alternate editor.  vipw performs a number of
      consistency checks on the password entry for root, and does not allow
      a password file with an incorrectly formatted root entry to be
      installed.

 WARNINGS
      An /etc/passwd.tmp file not removed when a system crashes prevents
      further editing of the /etc/passwd file using vipw after the system is
      rebooted.

 AUTHOR
