w(1)                    (BSD Compatibility Package)                    w(1)

NAME
     w - who is logged in, and what are they doing

SYNOPSIS
     /usr/ucb/w [-hls] [user]

DESCRIPTION
     The w command displays a summary of the current activity on the sys-
     tem, including what each user is doing. The heading line shows the
     current time of day, how long the system has been up, 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 [cf. sar(1), -q option and mpstat(1M)].

     The 7 fields displayed after the heading line are: 1) the user's login
     name, 2) the name of the tty the user is on, 3) the time of day the
     user logged on (in hours:minutes), 4) the idle time - that is, the
     number of minutes since the user last typed anything (in
     hours:minutes), 5) the CPU time used by all processes and their chil-
     dren on that terminal (in minutes:seconds), 6) the CPU time used by
     the currently active processes (in minutes:seconds), 7) the name and
     arguments of the current process.

     If a user name is included, output is restricted to that user.

OPTIONS
     -h   Suppress the heading.

     -l   Produce a long form of output, which is the default.

     -s   Produce a short form of output. In the short form, the tty is
          abbreviated, the login time and CPU times are left off, as are
          the arguments to commands.

     The CPU time is only an estimate, in particular, if someone leaves a
     background process running after logging out, the person currently on
     that terminal is charged with the time.

     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 com-
     mand is printed in parentheses.

     w does not know about the conventions for detecting background jobs.
     It will sometimes find a background job instead of the right one.
