LAST(1)LAST(1)NAMElast - display login and logout information about users and terminals
SYNOPSISlast [-a] [-n number | -number] [-f filename]
[name | tty]...
DESCRIPTION
The last command looks in the /var/adm/wtmpx file, which records all
logins and logouts, for information about a user, a terminal, or any
group of users and terminals. Arguments specify names of users or ter‐
minals of interest. If multiple arguments are given, the information
applicable to any of the arguments is printed. For example, last root
console lists all of root's sessions, as well as all sessions on the
console terminal. last displays the sessions of the specified users
and terminals, most recent first, indicating the times at which the
session began, the duration of the session, and the terminal on which
the session took place. last also indicates whether the session is con‐
tinuing or was cut short by a reboot.
The pseudo-user reboot logs in when the system is shutdown and when it
reboots. Thus,
last reboot
gives an approximate record of when the operating system instance was
shutdown and when it rebooted. This can be used to calculate the avail‐
ability of the operating system over time.
last with no arguments displays a record of all logins and logouts, in
reverse order.
If last is interrupted, it indicates how far the search has progressed
in /var/adm/wtmpx. If interrupted with a quit signal (generated by a
CTRL−\), last indicates how far the search has progressed, and then
continues the search.
OPTIONS
The following options are supported:
-a
Displays the hostname in the last column.
-f filename
Uses filename as the name of the accounting
file instead of /var/adm/wtmpx.
-n number|-number
Limits the number of entries displayed to that
specified by number. These options are identi‐
cal; the -number option is provided as a tran‐
sition tool only and is removed in future
releases.

LC_TIME, or LANG environments, in that order of priority.
