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

SYNOPSIS
       w [options] 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, --no-header
	      Don't print the header.

       -u, --no-current
	      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, --short
	      Use the short format.  Don't print the login time, JCPU or  PCPU
	      times.

       -f, --from
	      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.

       --help Display help text and exit.

       -i, --ip-addr
	      Display IP address instead of hostname for from field.

       -V, --version
	      Display version information.

       -o, --old-style
	      Old style output.	 Prints blank space for idle times  less  than
	      one minute.

       user   Show information about the specified user only.
