lastlog

LASTLOG(8)																LASTLOG(8)

NAME

       lastlog - examine lastlog file

SYNOPSIS

       lastlog [options]

DESCRIPTION

       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.

OPTIONS

       The options which apply to the lastlog command are:

       -h, --help
	      Print help message and exit.

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

       -u, --user LOGIN
	      Print the lastlog record for user with specified LOGIN only.

       The -t flag overrides the use of -u.

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

NOTE

       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 much smaller than the one shown by ls -l (which can indicate a really big file if you have a high UID). You can display
       its real size with ls -s.

FILES

       /var/log/lastlog
	      lastlog logging file

CAVEATS

       Large gaps in uid numbers will cause the lastlog program to run longer with no output to the screen (i.e. if mmdf=800 and last uid=170,
       program will appear to hang as it processes uid 171-799).
