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

SYNOPSIS
       w - [husfiV] [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 as
	    released is for the from field to not be  printed,	although  your
	    system  administrator or distribution maintainer may have compiled
	    a version in which the from field is shown by default.

       -i   Display IP address instead of hostname (if possible)

       -V   Display version information.

       user Show information about the specified user only.
