w(1)				 User Commands				  w(1)

NAME
       w - display information about currently logged-in users

SYNOPSIS
       w [-hlsuw] [user]

DESCRIPTION
       The w command displays a	summary	of the current activity	on the system,
       including what each user	is doing. The heading line shows  the  current
       time,  the  length  of time the system has been up, the number of users
       logged into the system, and the average number of jobs in the run queue
       over the	last 1,	5 and 15 minutes.

       The  fields  displayed  are: the	user's login name, the name of the tty
       the user	is on, the time	of day the user	logged on (in  hours:minutes),
       the idle	time--that is, the number of minutes since the user last typed
       anything	(in hours:minutes), the	CPU time used  by  all	processes  and
       their children on that terminal (in minutes:seconds), the CPU time used
       by the currently	active processes (in minutes:seconds),	and  the  name
       and arguments of	the current process.

OPTIONS
       The following options are supported:

       -h	Suppresses the heading.

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

       -s	Produces 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.

       -u	Produces  the  heading	line which shows the current time, the
		length of time the system has been up,	the  number  of	 users
		logged	into the system, and the average number	of jobs	in the
		run queue over the last	1, 5 and 15 minutes.

       -w	Produces a long	form of	output,	which is also the same as  the
		default.

OPERANDS
       user	Name  of  a particular user for	whom login information is dis-
		played.	If specified, output is	restricted to that user.

       that affect the execution of w: LC_CTYPE, LC_MESSAGES, and LC_TIME.

FILES

NOTES
       The  notion  of the "current process" is	unclear. The current algorithm
       is "the highest numbered	process	on the terminal	that is	 not  ignoring
       interrupts,  or,	 if there is none, the highest numbered	process	on the
       terminal". This fails, for example, in critical	sections  of  programs
       like the	shell and editor, or when faulty programs running in the back-
       ground fork and fail to ignore interrupts. In cases  where  no  process
       can be found, w prints -.

       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.
