LAST,LASTB(8)

NAME
last, lastb - show listing of last logged in users

SYNOPSIS
last [-R] [-num] [name...] [tty...]
lastb [-R] [-num] [name...] [tty...]

DESCRIPTION
Last searches back through the file /usr/adm/wtmp to show a list of all users logged in (and out) since that file was created. Names of users and tty's can be given, and then last will show only those entries matching the arguments. Names of ttys can be abbreviated, thus last 0 is the same as last tty0. When last catches a SIGINT (generated by the interrupt key, usually control-C) or a SIGQUIT (generated by the quit keys, sually control-\) last will show how far it was searching through the file and in the case of SIGINT last will terminate.

The pseudo user reboot logs in each time the system is rebooted. Thus last reboot will show a log of all reboots since the log file was created.

Lastb is the same as last, except that it shows a log of the file /etc/btmp which contains all the bad login attempts.

OPTIONS

-num
    This is a count telling last howmany lines to show.

-R  With this flag, the hostname field will be shown also.
