last(1) User Commands last(1)
NAME
last - display login and logout information about users and terminals
SYNOPSIS
last [-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 terminals 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
continuing 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
availability 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 identical; the -number
option is provided as a transition tool only and is removed in future releases.
ENVIRONMENT VARIABLES
Date and time format is based on locale specified by the LC_ALL, LC_TIME, or LANG environments, in that order of priority.
FILES
/var/adm/wtmpx accounting file
