NAME
last, lastb - indicate last logins of users and ttys
SYNOPSIS
/etc/last [-c] [-R] [-count] [name ...] [tty ...]
/etc/lastb [-c] [-R] [-count] [name ...] [tty ...]
DESCRIPTION
last searches backwards through file /etc/wtmp (which contains a
record of all logins and logouts) for information about a user, a tty,
or any group of users and ttys. Arguments specify names of users or
ttys of interest. Names of ttys can be given fully or abbreviated.
For example, last 0 is the same as last tty0. If multiple arguments
are given, the information that applies to any of the arguments is
printed. For example, last root console lists all of root's sessions
as well as all sessions on the console terminal. last prints the
sessions of the specified users and ttys, most recent first,
indicating when the session began, the duration of the session, and
the tty on which the session took place. If the session is still
continuing or was cut short by a reboot, last so indicates.
The pseudo-user reboot logs each time the system reboots. Thus last
reboot is a useful command for evaluating the relative time between
system reboots.
last recognizes the following options and arguments:
(none) If no arguments are specified, last prints a record of
all logins and logouts in reverse order, most recent
first.
-c Displays login information for all cnodes of an HP
Cluster (see glossary(9)).
-count Limits the report to count lines. When used in
conjunction with the -c option, the limit is applied
independently for each cnode in the cluster.
-R When used with last and lastb, -R displays the user's
host name as it is stored in files /etc/wtmp and
/etc/btmp respectively. The host name is displayed
between the tty name and the user's login time.
If last is interrupted, it indicates how far the search has progressed
in wtmp. If interrupted by a quit signal (generated by a Ctrl-\), last
indicates how far the search has progressed, then continues the
search.
lastb searches backwards through the database file /etc/btmp to
display bad login information. Access to /etc/btmp should be
restricted to users with appropriate privileges (owned by and readable
