.Sh NAME

.Nd edit the password file
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl d Ar directory
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility 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
|
|
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
|
|
The
|
|
.Nm
|
|
utility 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 :
|
|
.Bl -tag -width PW_SCAN_BIG_IDS
|
|
.It Ev EDITOR
|
|
The editor specified by the string
|
|
.Ev EDITOR
|
|
will be invoked instead of the default editor
|
|
.Xr vi 1 .
|
|
This can be used to allow a script to non-interactively modify the
|
|
password file.

|

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
utility appeared in
|
|
.Bx 4.0 .
|
|
.Sh BUGS
|
|
The mechanism for checking for password file modifications requires that
|
|
the modification time of the password file changes.
|
|
This means that in a default configuration where file system timestamps
|
|
are not calculated with sub-second precision,
|
|
.Ev EDITOR
|
|
has to run for at least one second.
|
|
Non-interactive editor scripts should invoke
|
|
.Xr sleep 1
|
|
or equivalent to ensure this happens.
