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
