The Zones project (PSARC/2002/174) introduced a new process attribute,
the zone with which each process is associated.  Although that case
updated the ps(1) command to be able to print zone associations using
the "-o <format>" syntax, and this can be combined with grep, pgrep,
awk, etc. to filter the output based on zone, customers have requested
a more convenient syntax for filtering and displaying zone information
using ps.

We propose adding two new options to ps(1), -z and -Z.  The output when
neither option is used will be unchanged.

Although the ps command as a whole is classified as Standard, these
options are proposed as Stable, with the output when these options are
used classified as Unstable.  A release binding of Patch is requested.

Sample output:

# ps -AZ
    ZONE    PID TTY         TIME CMD
  global      0 ?           0:09 sched
  global      1 ?           0:00 init
[...]
  myzone 100426 ?           0:00 zsched
[...]
# ps -fZ -z myzone
    ZONE     UID    PID   PPID   C    STIME TTY         TIME CMD
  myzone    root 100426      1   0   Mar 15 ?           0:00 zsched
  myzone    root 100648 100429   0   Mar 15 ?           0:00 /usr/lib/saf/sac -t 300
