NAMN

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

SYNOPSIS

       lastlog [flaggor]

BESKRIVNING

       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.

FLAGGOR

       Flaggorna som gäller för kommandot lastlog är:

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

       -h, --help
           Visa hjälpmeddelande och avsluta.

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

       -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.

       Only the entries for the current users of the system will be displayed. Other entries may
       exist for users that were deleted previously.

NOTERA

       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".

FILER

       /var/log/lastlog
           Databastider för tidigare användarinloggningar.

TÄNK

       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).
