LAST(1) MachTen Reference Manual LAST(1)
NAME
last - indicate last logins of users and ttys
SYNOPSIS
last [-n] [-f file] [-h host] [-t tty] [user ...]
DESCRIPTION
Last will list the sessions of specified users, ttys, and
hosts, in re-
verse time order. Each line of output contains the user
name, the tty
from which the session was conducted, any hostname, the
start and stop
times for the session, and the duration of the session. If
the session
is still continuing or was cut short by a crash or shutdown,
last will so
indicate.
-f file Last reads the file file
instead of the default,
/var/log/wtmp.
-n Limits the report to n lines.
-t tty Specify the tty. Tty
names may be given fully or abbreviated,
for example, ‘‘last -t 03’’ is
equivalent to ‘‘last -t
tty03’’.
-h host Host names may be names or internet numbers.
If multiple arguments are given,
the information which applies to any of
the arguments is printed, e.g., ‘‘last root -t
console’’ would list all
of ‘‘root’s’’ sessions as well
as all sessions on the console terminal.
If no users, hostnames or terminals are specified, last
prints a record
of all logins and logouts.
The pseudo-user reboot logs in
at reboots of the system, thus ‘‘last
reboot’’ will give an indication of mean time
between reboot.
If last is interrupted, it
indicates to what date the search has pro-
gressed. If interrupted with a quit signal last indicates
how far the
search has progressed and then continues.
