prwarn(C)                       19 June 1992                       prwarn(C)


 Name

    prwarn - warn about password expiration

 Syntax

    prwarn [ -d days ] [ -t hh[mm] ] [ users ]

 Description

    prwarn issues a warning if the user's password must be changed within
    days and the user has not been warned of the impending expiry in the last
    hhmm, where hh is hours and mm is minutes.  By default, warnings will be
    issued if the password is due to expire within seven days, at six hour
    intervals.

    If days is infinite, and no warning has been issued in the last hh[mm], a
    warning is given. If hh[mm] is always, and the password must be changed
    within days, a warning is issued. Thus:

       prwarn -d infinite -t always

    always issues a warning.

    If no users are specified, then the logged-in user is assumed and the
    time that the last report was issued is the modification time of
    .prwarn_time in the user's home directory.

    System administrators (users with the auth subsystem authorization or
    passwd secondary authorization) may check the password expiry status of
    other users; the time interval between reports being issued is not
    checked.

    The number of days left before the password expires, the date at which
    the password expires, and whether the password can still be changed or is
    dead (expired and exceeded its lifetime) is reported.

 Files

    /usr/bin/prwarn
    $HOME/.prwarn_time      used to check time of last warning
