.SH DESCRIPTION
|
|
\fBLast\fP looks back in the \fBwtmp\fP 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. If multiple arguments are given, the information which
|
|
applies to any of the arguments is printed. For example ``\fBlast root
|
|
console\fP'' would list all of root's sessions as well as all sessions
|
|
on the console terminal. \fBLast\fP displays 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, \fBlast\fP so indicates.
|
|
.LP
|
|
The pseudo-user \fBreboot\fP logs in at reboots of the system.
|
|
.LP
|
|
\fBLast\fP with no arguments displays a record of all logins and
|
|
logouts, in reverse order.
|
|
.LP
|
|
If \fBlast\fP is interrupted, it indicates how far the search has
|
|
progressed in \fBwtmp\fP. If interrupted with a quit signal \fBlast\fP
|
|
indicates how far the search has progressed so far, and the search
|
|
continues.
