w Command
  
  
  Purpose
  
  Prints a summary of current system activity.
  
   Syntax
  
  w [  -h ] [  -u ] [  -w ] [  -l |  -s ] [ User ]
  
  Description
  
  The w command prints a summary of the current activity on the
  system.  The summary includes the following:
  
  *	Who is logged on
  
  *	What each user is doing
  
  *	Name of the tty the user is on
  
  *	Time of day the user logged on
  
  *	Number of minutes since the user last typed anything
  
  *	System unit time used by all processes and their children on
  that terminal
  
  *	System unit time used by the currently active process
  
  *	Name and arguments of the current process
  
  The heading line of the summary shows the current time of day,
  how long the  system has been up, the number of users logged into
  the system, and the number of runable processes.
  
  The following examples show the different formats used for the
  login time field:
  
  10:25am	The user logged in within the last 24 hours.
  
  Tue10am	The user logged in between 24 hours and 7 days.
  
  12Mar91	The user logged in more than 7 days ago.
  
  If a user name is specified with the User parameter, the output
  is restricted to that user.
  
  Flags
  
  -h	Suppresses the heading.
  
  -l	Prints the summary in long form.  This is the default.
  
  -s	Prints the summary in short form.  In the short form, the tty
  is abbreviated, and the login time, system unit time, and command
  arguments are omitted.
  
  -u	Prints the time of day, amount of time since last system
  startup,  number of users logged on, and number of processes run-
  ning.  This is the default.  Specifying the -u flag without
  specifying the -w or -h flag is equivalent to the  uptime com-
  mand.
  
  -w	The equivalent of specifying the -u and -l flags, which is the
  default.
