NAME
last - indicate last logins of users and ttys
SYNOPSIS
last [-n] [-T] [-f file] [-H hostsize] [-h host] [-L linesize] [-N
namesize] [-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.
-n Limits the report to n lines.
-f file last reads the file file instead of the default,
/var/log/wtmpx or /var/log/wtmp. If the file ends with
`x', it is treated as a utmpx(5) format file, else it is
treated as a utmp(5) format file.
-H hostsize Use the provided hostsize as the width to format the host
name field.
-h host Host names may be names or internet numbers.
-L linesize Use the provided linesize as the width to format the tty
field.
-N namesize Use the provided namesize as the width to format the login
name field.
-T Display better time information, including the year and
seconds.
-t tty Specify the tty. Tty names may be given fully or abbrevi-
ated, for example, ``last -t 03'' is equivalent to ``last
-t tty03''.
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.
