NAME
    w - show who is logged on and what they are doing

SYNOPSIS
    w - [-husfV] [user]

DESCRIPTION
    w displays information  about the users currently on the machine, and
    their processes.  The header shows, in this order, the current  time,
    how long the system has been running, how many users are currently
    logged on, and the system load averages for the past 1, 5, and 15 min-
    utes.

    The following entries are displayed for each user: login name, the tty
    name, the remote host, login time, idle time, JCPU, PCPU, and the com-
    mand line of their current process.

    The JCPU time is the time used by all processes attached to the tty.
    It does not include past background jobs, but does include currently
    running background jobs.

    The PCPU time is the time used by the current process, named in the
    "what" field.

COMMAND-LINE OPTIONS
    -h  Don't print the header.

    -u  Ignores the username while figuring out the  current process and
   cpu  times.  To demonstrate this, do a "su" and do a "w" and a "w
   -u".

    -s  Use the short format. Don't print the login time, JCPU or PCPU
   times.

    -f  Toggle printing the from (remote hostname) field. The default if
   for the from field to be printed, although your system administra-
   tor  or distribution maintainer may have compiled a version in
   which the from field is not shown by default.

    -V  Display version information.

    user Show information about the specified user only.
