W(1)			      Linux User's Manual			  W(1)

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.
