NAME
     vipw -- edit the password file

SYNOPSIS
     vipw [-d directory]

DESCRIPTION
     The  vipw	utility  edits	the  password file after setting the appropriate
     locks, and does any necessary processing after the  password  file  is  un-
     locked.   If  the	password  file	is already locked for editing by another
     user, vipw will ask you to try again later.  The default editor for vipw is
     vi(1).

     When run without options, vipw will work with the password files  in  /etc.
     The -d option may be used to specify an alternative directory to work with.

     The  vipw	utility  performs a number of consistency checks on the password
     entries, and will not allow a password file with a "mangled"  entry  to  be
     installed.   If vipw rejects the new password file, the user is prompted to
     re-enter the edit session.

     Once the information has been verified, vipw uses pwd_mkdb(8) to update the
     user database.  This is run in the background, and,  at  very  large  sites
     could  take  several minutes.  Until this update is completed, the password
     file is unavailable for other updates and the new information is not avail-
     able to programs.

ENVIRONMENT
     If the following environment variable exists it will be utilized by vipw:

     EDITOR	      The editor specified by the string EDITOR will be  invoked
		      instead of the default editor vi(1).

     PW_SCAN_BIG_IDS  See pwd_mkdb(8).

     The vipw utility appeared in 4.0BSD.
