Name
       vipw - edit the password file

Syntax
       vipw

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

       If the hashed database exists will automatically invoke on it to keep it synchronized with the file.
