10: last \- indicate last logins of users and ttys
11: .SH SYNOPSIS
12: \fBlast\fP [-#] [-f file] [-h host] [-t tty] [user ...]
13: .SH DESCRIPTION
14: \fILast\fP will list the sessions of specified \fIusers,\fP \fIttys,\fP
15: and \fIhosts,\fP in reverse time order. Each line of output contains
16: the user name, the tty from which the session was conducted, any
17: hostname, the start and stop times for the session, and the duration
18: of the session. If the session is still continuing or was cut short by
19: a crash or shutdown, \fIlast\fP will so indicate.
20: .PP
21: \fILast\fP reads the file \fIfile\fP, or by default, \fI/usr/adm/wtmp\fP.
22: The \fB-#\fP option limits the report to \fB#\fP lines.
23: .PP
24: Other arguments specify \fIusers,\fP \fIttys\fP or \fIhosts\fP of interest.
25: Tty names may be given fully or abbreviated, e.g., ``last -t 03'' is
26: equivalent to ``last -t tty03''. Host names may be internet numbers. If
27: multiple arguments are given, the information which applies to any of the
28: arguments is printed, e.g., ``last root -t console'' would list all of
29: ``root's'' sessions as well as all sessions on the console terminal. If no
30: users, hostnames or terminals are specified, \fIlast\fP prints a record of
31: all logins and logouts.
32: .PP
33: The pseudo-user \fBreboot\fP logs in at reboots of the system, thus
34: ``last reboot'' will give an indication of mean time between reboot.
35: .PP
36: If \fIlast\fP is interrupted, it indicates to what date the search has
37: progressed. If interrupted with a quit signal \fIlast\fP indicates how
38: far the search has progressed and then continues.
