DESCRIPTION

The last command will look back in the wtmp file which records all logins and
logouts for information about a user, a teletype or any group of users and
teletypes.  Arguments specify names of users or teletypes of interest.  Names
of teletypes may be given fully or abbreviated.  For example last 0 is the same
as last tty0.  If multiple arguments are given, the information which applies
to any of the arguments is printed.  For example last root console would list
all of root's sessions as well as all sessions on the console terminal.  The
last command will print the sessions of the specified users and teletypes, most
recent first, indicating the times at which the session began, the duration of
the session, and the teletype which the session took place on.  If the session
is still continuing or was cut short by a reboot, last so indicates.

The pseudo-user reboot logs in at reboots of the system, thus

  last reboot

will give an indication of mean time between reboot.

The last command with no arguments prints a record of all logins and logouts,
in reverse order.

If last is interrupted, it indicates how far the search has progressed in wtmp.
If interrupted with an INTERRUPT signal (generated by a Ctrl-C), last indicates
how far the search has progressed so far, and the search continues.
