20 21 .sp
21 22 .LP
22 23 The \fBprstat\fR utility iteratively examines all active processes on the
23 24 system and reports statistics based on the selected output mode and sort order.
24 25 \fBprstat\fR provides options to examine only processes matching specified
25 26 \fBPID\fRs, \fBUID\fRs, zone \fBID\fRs, \fBCPU\fR \fBID\fRs, and processor set
26 27 \fBID\fRs.
27 28 .sp
28 29 .LP
29 30 The \fB-j\fR, \fB-k\fR, \fB-C\fR, \fB-p\fR, \fB-P\fR, \fB-u\fR, \fB-U\fR, and
30 31 \fB-z\fR options accept lists as arguments. Items in a list can be either
31 32 separated by commas or enclosed in quotes and separated by commas or spaces.
32 33 .sp
33 34 .LP
34 35 If you do not specify an option, \fBprstat\fR examines all processes and
35 36 reports statistics sorted by \fBCPU\fR usage.
36 37 .SH OPTIONS

69 71 list. Each processor set is identified by an integer as reported by
70 72 \fBpsrset\fR(1M). The load averages displayed are the sum of the load averages
71 73 of the specified processor sets (see \fBpset_getloadavg\fR(3C)). Processes with
72 74 one or more LWPs bound to processor sets in the given list are reported even
73 75 when the \fB-L\fR option is not used.
