SINOSSI


       lastlog [opzioni]

DESCRIZIONE

       lastlog formats and prints the contents of the last login log /var/log/lastlog file. The login-name,
       port, and last login time will be printed. The default (no flags) causes lastlog entries to be printed,
       sorted by their order in /etc/passwd.

OPZIONI

       The options which apply to the lastlog command are:

       -b, --before DAYS
           Print only lastlog records older than DAYS.

       -C, --clear
           Clear lastlog record of a user. This option can be used only together with -u (--user)).

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

       -R, --root CHROOT_DIR
           Apply changes in the CHROOT_DIR directory and use the configuration files from the CHROOT_DIR
           directory. Only absolute paths are supported.

       -S, --set
           Set lastlog record of a user to the current time. This option can be used only together with -u
           (--user)).

       -t, --time DAYS
           Print the lastlog records more recent than DAYS.

       -u, --user LOGIN|RANGE
           Mostra il record di ultimo accesso per l'utente o gli utenti specificati da LOGIN.

           The users can be specified by a login name, a numerical user ID, or a RANGE of users. This RANGE of
           users can be specified with a min and max values (UID_MIN-UID_MAX), a max value (-UID_MAX), or a min
           value (UID_MIN-).

       If the user has never logged in the message ** Never logged in** will be displayed instead of the port
       and time.

       Solo le registrazioni degli utenti correnti del sistema verranno mostrate. Ci potrebbero essere altre
       registrazioni per utenti cancellati in precedenza.

NOTA

       The lastlog file is a database which contains info on the last login of each user. You should not rotate
       it. It is a sparse file, so its size on the disk is usually much smaller than the one shown by "ls -l"
       (which can indicate a really big file if you have in passwd users with a high UID). You can display its
       real size with "ls -s".

CONFIGURAZIONE

       The following configuration variables in /etc/login.defs change the behavior of this tool:

FILE

       /var/log/lastlog
           Database degli orari dei precedenti accessi utente.

AVVISI/CAVEAT

       Se ci sono dei grossi scarti tra i valori di UID, il programma lastlog può restare in esecuzione per un
       tempo prolungato senza produrre output sullo schermo (ad es. se nel database lastlog non ci sono
       registrazioni per UID tra 170 e 800, il programma sembrerà bloccato mentre esamina gli UID tra 171 e
       799).

       Having high UIDs can create problems when handling the <term> /var/log/lastlog</term> with external
       tools. Although the actual file is sparse and does not use too much space, certain applications are not
       designed to identify sparse files by default and may require a specific option to handle them.
