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).
