       top - display and update information about the top cpu processes

OPTIONS
       -C     Toggle CPU display mode.  By default top displays  the  weighted
              CPU  percentage  in the WCPU column (this is the same value that
              ps(1) displays as CPU).  Each time -C flag is passed it  toggles
              between  "raw  cpu"  mode  and  "weighted cpu" mode, showing the
              "CPU" or the "WCPU" column respectively.


       -S     Show system processes in the  display.   Normally,  system  pro-
              cesses  such  as  the pager and the swapper are not shown.  This
              option makes them visible.

       -I     Do not display idle processes.  By default,  top  displays  both
              active and idle processes.

       -P     Display per-cpu CPU usage statistics.

example:

top -P 

top -IS
