The branch stable/13 has been updated by 0mp (doc, ports committer): URL: https://cgit.FreeBSD.org/src/commit/?id=b879d2b81a4da43536856842472c48ff5fb7267c commit b879d2b81a4da43536856842472c48ff5fb7267c Author: Mateusz Piotrowski <0mp@FreeBSD.org> AuthorDate: 2022-03-31 14:30:29 +0000 Commit: Mateusz Piotrowski <0mp@FreeBSD.org> CommitDate: 2022-06-29 08:15:14 +0000 ifconfig.8: Document "ifconfig -g groupname" "ifconfig -g groupname" prints a list of interface names, which could be confusing, because it differs from the behavior of "ifconfig -a -g groupname". While here, add two examples showing the difference between "ifconfig -a -g groupname" and "ifconfig -g groupname". Fixes: 0dad3f0e1512 Import interface groups from OpenBSD.
