The?prstat?utility?iteratively?examines?all?active?processes?on?the?system?and?reports
statistics?based?on?the?selected?output?mode?and?sort?order.?prstat?provides?options
to?examine?only?processes?matching?specified?PIDs,?UIDs,?zone?IDs,?CPU?IDs,?and
processor?set?IDs.
The?-j,?-k,?-C,?-p,?-P,?-u,?-U,?and?-z?options?accept?lists?as?arguments.?Items?in?a?list
can?be?either?separated?by?commas?or?enclosed?in?quotes?and?separated?by?commas?or

If?you?do?not?specify?an?option,?prstat?examines?all?processes?and?reports?statistics
sorted?by?CPU?usage.
The?following?options?are?supported:

averages?displayed?are?the?sum?of?the?load?averages?of?the?specified?processor?sets
(see?pset_getloadavg(3C)).?Processes?with?one?or?more?LWPs?bound?to
