w utility prints a summary of the current activity
  on the system, including what each user is doing. The first line displays the
  current time of day, how long the system has been running, the number of users
  logged into the system, and the load averages. The load average numbers give
  the number of jobs in the run queue averaged over 1, 5, and 15 minutes. The
  load average is obtained using
  getloadavg(3).
The fields output are the user's login name, the name of the terminal the user is on, the host from which the user is logged in, the time the user logged on, the time since the user last typed anything, and the name and arguments of the current process.
The options are as follows:
-h-i-M-N-nw
      interprets addresses and attempts to display them symbolically).-wIf a user name is specified, the output is restricted to that user.
w command appeared in
  3.0BSD.
w prints “-”.)
Background processes are not shown, even though they account for much of the load on the system.
Sometimes processes, typically those in the background, are printed with null or garbaged arguments. In these cases, the name of the command is printed in parentheses.
The w utility does not know about the new
    conventions for detection of background jobs. It will sometimes find a
    background job instead of the right one.
