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

       w - [husfV] [user]

       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 minutes.

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

       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.

       -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.

       -V   Display version information.

       user Show information about the specified user only.

       /etc/utmp information about who	is  currently  logged  on
       /proc process information

       free(1), ps(1), top(1), uptime(1), utmp(5), who(1)

       w  was  re-written almost entirely by Charles Blake, based
       on the version by  Larry	 Greenfield  <greenfie@gauss.rut­> and Michael K. Johnson <>.
