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.
