|
|
.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 .
