  54 the user name, the tty from which the session was conducted, any
  55 hostname, the start and stop times for the session, and the duration
  56 of the session.  If the session is still continuing or was cut short by

  80 multiple arguments are given, the information which applies to any of the
  81 arguments is printed, e.g.,
  82 .Dq Li "last root -t console"
  83 would list all of
  84 .Dq Li root Ns 's
  85 sessions as well as all sessions on the console terminal. If no
  86 users, hostnames or terminals are specified,
  87 .Nm
  88 prints a record of
  89 all logins and logouts.
  90 .Pp
  91 The pseudo-user
  92 .Ar reboot
  93 logs in at reboots of the system, thus
  94 .Dq Li last reboot
  95 will give an indication of mean time between reboot.
  96 .Pp
  97 If
