NAME
lastlog - examine lastlog file SYNOPSIS
lastlog [<-u|--user> login-name] [<-t|--time> days] [<-h|--help>] 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 the numerical UID. -u, --user login-name will cause the lastlog record for login-name only to be printed -t, --time days will cause only the lastlogins more recent han fIdays to be printed -h, --help print a one-line help message and exit. 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. 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). AUTHORS

NAME
lastlog - reports the most recent login of all users or of a given user 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: -b, --before DAYS Print only lastlog records older than DAYS. -h, --help Display help message and exit. -R, --root CHROOT_DIR Apply changes in the CHROOT_DIR directory and use the configuration files from the CHROOT_DIR directory. -t, --time DAYS 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. 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 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". FILES
/var/log/lastlog Database times of previous user logins. CAVEATS
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). shadow-utils 4.1.5.1 05/25/2012 LASTLOG(8)
