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 session is still continuing or was cut short by a crash or
  shutdown, last will so indicate.
The following options are available:
-n-f
    filelast reads the file file
      instead of the default, /var/log/wtmpx or
      /var/log/wtmp. If the file ends with
      ‘x’, it is treated as a
      utmpx(5) format file, else it
      is treated as a utmp(5) format
      file. If the file is ``-'', standard input is used.-H

      03” is equivalent to “last -t
      tty03”.-xIf 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.
