LAST(1) BSD General Commands 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 reverse 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 ses-
sion 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 progressed. If interrupted with a quit signal last indicates how far the
search has progressed and then continues.

last(1) General Commands Manual last(1)Name
last - indicate last logins of users and teletypes
Syntax
last [-N] [name...] [tty...]
Description
The command looks back in the file, which records all logins and logouts, for information about a user, a teletype or any group of users
and teletypes. Arguments specify names of users or teletypes of interest. Names of teletypes can be given fully or abbreviated. For
example `last 0' is the same as `last tty0'.
If multiple arguments are given, the information that applies 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.
The command prints the sessions of the specified users and teletypes, most recent first, indicating the times at which the session began,
the duration of the session, and the teletype on which the session took place. If the session is ongoing or was cut short by a reboot,
indicates that this is so.
The pseudo-user reboot logs in at reboots of the system. Therefore, the following example gives an indication of mean time between reboot:
last reboot
The command with no arguments prints a record of all logins and logouts, in reverse order.
If is interrupted, it indicates how far the search has progressed in If interrupted with a quit signal (generated by a <CTRL/E>) indicates
how far the search has progressed so far, and the search continues.
Options-N Limits the number of output lines to the specified number.

I have several users connecting via a Windows-based SSH\telnet client. The previous sysadmin used FacetTerm to allow certain users to switch between multiple "windows." I'm told there are AIX-native ways to do this but I work with what I inherited.
