       chage - cambia le informazioni sulla scadenza della password

SINOSSI

       chage [opzioni] LOGIN

DESCRIZIONE

       The chage command changes the number of days between password changes and the date of the
       last password change. This information is used by the system to determine when a user must
       change their password.

OPZIONI

       The options which apply to the chage command are:

       -d, --lastday LAST_DAY
           Imposta la data dell'ultimo cambio della password, espressa come il numero di giorni
           trascorsi dal 1 gennaio 1970. La data può anche essere specificata nel formato
           AAAA-MM-GG o nella notazione comunemente usata nel proprio paese.

       -E, --expiredate EXPIRE_DATE
           Imposta la data o il numero di giorni dal 1 gennaio 1970 dal quale l'account utente
           non sarà più accessibile. La data può essere inserita nel formato AAAA-MM-GG (o il
           formato più comunemente utilizzato nel proprio paese). Un utente il cui account sia
           bloccato deve contattare l'amministratore di sistema prima di poter accedere
           nuovamente al sistema.

           Passing the number -1 as the EXPIRE_DATE will remove an account expiration date.

       -h, --help
           Mostra un messaggio di aiuto ed esce.

       -i, --iso8601
           When printing dates, use YYYY-MM-DD format.

       -I, --inactive INACTIVE
           Set the number of days of inactivity after a password has expired before the account
           is locked. The INACTIVE option is the number of days of inactivity. A user whose
           account is locked must contact the system administrator before being able to use the
           system again.

           Passing the number -1 as the INACTIVE will remove an account's inactivity.

       -l, --list
           Visualizza le informazioni sulla scadenza dell'account.

       -m, --mindays MIN_DAYS
           Set the minimum number of days between password changes to MIN_DAYS. A value of zero
           for this field indicates that the user may change their password at any time.

       -M, --maxdays MAX_DAYS
           Set the maximum number of days during which a password is valid. When MAX_DAYS plus
           LAST_DAY is less than the current day, the user will be required to change their
           password before being able to use their account. This occurrence can be planned for in
           advance by use of the -W option, which provides the user with advance warning.

           Passing the number -1 as MAX_DAYS will remove checking a password's validity.

       -R, --root CHROOT_DIR
           Apply changes in the CHROOT_DIR directory and use the configuration files from the
           CHROOT_DIR directory.

       -W, --warndays WARN_DAYS
           Set the number of days of warning before a password change is required. The WARN_DAYS
           option is the number of days prior to the password expiring that a user will be warned
           their password is about to expire.

       If none of the options are selected, chage operates in an interactive fashion, prompting
       the user with the current values for all of the fields. Enter the new value to change the
       field, or leave the line blank to use the current value. The current value is displayed
       between a pair of [ ] marks.

NOTA

       The chage program requires a shadow password file to be available.

       The chage command is restricted to the root user, except for the -l option, which may be
       used by an unprivileged user to determine when their password or account is due to expire.
