Bug ID: 263667
Summary: ifconfig: group flags -g and -G not consistent with
expectation or man page
Product: Base System
Version: Unspecified
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: bin

FreeBSD js1 13.1-RC4 FreeBSD 13.1-RC4 releng/13.1-n250133-283d1b98251 GENERIC
amd64
The group-selection flags' behavior is not sufficient to get a simple
(actionable)
list of interfaces that are members of one group and not another.
The man page, as I understand it, suggests that this should be possible.
[jeff@js1 ~/devel/jail-networking]$ /sbin/ifconfig -g @jname-si-real -G bridge
vif0
vif0/jname-si-
bridge6
Expected vif0 and vif0/jname-si-
[jeff@js1 ~/devel/jail-networking]$ /sbin/ifconfig -a -g @jname-si-real -G
bridge
vif0: flags=8863<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
options=8<VLAN_MTU>
ether 02:c1:6f:13:e8:0a
groups: epair @jname-si-real
media: Ethernet 10Gbase-T (10Gbase-T <full-duplex>)
status: active
nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
vif0/jname-si-: flags=8963<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST>
metric 0 mtu 1500
options=8<VLAN_MTU>
ether 02:c1:6f:13:e8:0b
groups: epair @jname-si-real
media: Ethernet 10Gbase-T (10Gbase-T <full-duplex>)
status: active
nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>
Works, but needs to be processed as text to become an actionable list
sus as `for lvar in $(/sbin/ifconfig some args) ; do `
For reference
