In SRU 75 of Solaris 11.4 two options were added to pgrep and pkill. The first option is -Z. With this option you can limit both commands to the current process’s zone.
root@testbed:~# ps -efZ | grep utmpd
global daemon 200 1 0 05:58:33 ? 0:00 /usr/lib/utmpd
testzone daemon 1837 1703 0 07:57:48 ? 0:00 /usr/lib/utmpd
root@testbed:~# pgrep utmpd
200
1837
root@testbed:~# pgrep -Z utmpd
200
The second new option is -r. This option allows you to limit pgrep to the processes dependent on the process you have specified with a PID.
root@testbed:~# pgrep -r 1703
1703
1712
1714
1793
1822
1837
1839
1874
1894
1902
If you cross-check this with ptree you will see the same processes (except the parent process of 1703):
root@testbed:~# ptree 1703
1648 zsched
1703 /usr/sbin/init
1712 /lib/svc/bin/svc.startd
1874 /usr/bin/sh /lib/svc/method/milestone-config start
1894 /usr/bin/python3.11 -Es ....
1903 <defunct>
1714 /lib/svc/bin/svc.configd
1793 /usr/sbin/sysobjd -d 0 -b 300 -t 300 -n 5
1822 /lib/inet/ipmgmtd
1837 /usr/lib/utmpd
1839 /usr/lib/rad/rad -sp
1902 /usr/lib/rad/rad -m ....
The same options work for pkill.
