Nik Clayton 414a35e60a Add $Id$, to make it simpler for members of the translation teams to
track.

The Id line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

     .\"    $Id$
     .\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

.Sh NAME
.Nm vipw
.Nd edit the password file
.Sh SYNOPSIS
.Nm vipw
.Op Fl d Ar directory
.Sh DESCRIPTION
.Nm 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,
.Nm
will ask you
to try again later. The default editor for
.Nm
is
.Xr vi 1 .
.Pp
When run without options,
.Nm vipw
will work with the password files in
.Pa /etc .
The
.Fl d
option may be used to specify an alternative
.Ar directory
to work with.
.Pp
.Nm Vipw
performs a number of consistency checks on the password entries,
and will not allow a password file with a
.Dq mangled
entry to be
installed.
If
.Nm
rejects the new password file, the user is prompted to re-enter
the edit session.
.Pp
Once the information has been verified,
.Nm
uses
.Xr 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.
.Sh ENVIRONMENT
If the following environment variable exists it will be utilized by
.Nm Ns :
.Bl -tag -width EDITOR
.It Ev EDITOR
The editor specified by the string
.Ev EDITOR
will be invoked instead of the default editor
.Xr vi 1 .
.El
.Sh SEE ALSO
.Xr chpass 1 ,
.Xr passwd 1 ,
.Xr passwd 5 ,
.Xr adduser 8 ,
.Xr pwd_mkdb 8
.Sh HISTORY
The
.Nm
command appeared in
.Bx 4.0 .
