Follow-up Comment #9, bug #42501 (group findutils): I realise I didn't really answer the question of which *release* -E came in in those.
For FreeBSD and NetBSD, that would be their respective 5.0 version even if they're many years apart. For MacOS/X I don't know exactly, but https://github.com/NetBSD/src/blob/trunk/share/misc/bsd-family-tree suggests that could be 10.3 which is meant to have synced with FreeBSD 5.1 DragonFly BSD from the start (2003), I've not checked any other FreeBSD derivative (https://en.wikipedia.org/wiki/Comparison_of_BSD_operating_systems#FreeBSD). OpenBSD's find doesn't have -E, I've not checked any of its derivatives (like MirBSD). _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?42501> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
