+.TH LAST 1 "March 1992" "util-linux" "User Commands"
+.SH NAME
+last \(em indicate last logins by user or terminal
+.SH SYNOPSIS
+.ad l
+.B last
+.RB [ \-\fP\fInumber\fP ]
+.RB [ \-f
+.IR filename ]
+.RB [ \-t
+.IR tty ]
+.RB [ \-h
+.IR hostname ]

+.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.
+.SH OPTIONS
+.IP \fB\-\fP\fInumber\fP
+limit the number of entries displayed to that specified by \fInumber\fP.
+.IP "\fB\-f\fP \fIfilename\fP"
+Use \fIfilename\fP as the name of the accounting file instead of
+.BR /var/log/wtmp .
+.IP "\fB\-h\fP \fIhostname\fP"
+List only logins from \fIhostname\fP.
+.IP "\fB\-i\fP \fIIP address\fP"
+List only logins from \fIIP address\fP.
+.IP "\fB\-l\fP"
+List IP addresses of remote hosts instead of truncated host names.
+.IP "\fB\-t\fP \fItty\fP"
+List only logins on \fItty\fP.
+.IP "\fB\-y\fP"
+Also report year of dates.
+.SH FILES
+/var/log/wtmp \(em login data base
+.SH AVAILABILITY

+ftp://ftp.kernel.org/pub/linux/utils/util-linux/.
