       lastlog - reports the most recent login of all users or of a given user


       lastlog [opzioni]


       lastlog mostra il log degli ultimi accessi, contenuto nel file
       /var/log/lastlog. Le informazioni mostrate sono il nome utente, la
       porta, e la data dell´ultimo accesso. Il comportamento predefinito
       (nessuna opzione specificata) è di mostrare i record di ultimo accesso
       per tutti gli utenti, nell´ordine in cui compaiono in /etc/passwd.


       Il comando lastlog accetta le seguenti opzioni:

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

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

       -t, --timeGIORNI
           Mostra solo i record di ultimo accesso più recenti di un numero di

       -u, --user LOGIN|RANGE
           Print the lastlog record of the specified user(s).

           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.


       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".


           Database times of previous user logins.


       Large gaps in UID numbers will cause the lastlog program to run longer
       with no output to the screen (i.e. if in lastlog database there is no
       entries for users with UID between 170 and 800 lastlog will appear to
       hang as it processes entries with UIDs 171-799).
