.SH NAME
last \- indicate last logins of users and teletypes
.SH SYNOPSIS
.B last
[
name ...
] [
tty ...
]
.SH DESCRIPTION
.I Last
will look back in the
.I 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.
.I Last
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 crash,
.I last
so indicates.
.PP
The teletype
.B tty~
records the crashes of the system; thus
.DT
.PP
	last tty~
.PP
will give an indication of the reliability of the system.
.PP
.I Last
with no arguments prints a record of all logins and logouts, in
reverse order.
.PP
If
.I last
is interrupted, it indicates how far the search has progressed
in
.I wtmp.
