NetBSD 6.1.5 - man page for vipw (netbsd section 8)

VIPW(8) 			   BSD System Manager's Manual				  VIPW(8)

     vipw -- edit the password file

     vipw [-d directory]

     vipw edits the password file after setting the appropriate locks, and does any necessary
     processing after the password file is unlocked.  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).

     vipw 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 available to programs.

     The options are as follows:

     -d directory
	   Change the root directory of the password file from ``/'' to directory.

     If a vipw session is killed it may leave ``/etc/ptmp'', which will cause future vipw execu-
     tions to fail with ``vipw: the passwd file is busy'', until it is removed.

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

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

     /etc/master.passwd 	       The current password file.
     /etc/ptmp			       Temporary copy of the password file used while editing.

     chpass(1), passwd(1), pwhash(1), passwd(5), passwd.conf(5), pwd_mkdb(8), user(8)

     The vipw command appeared in 4.0BSD.
