The branch stable/14 has been updated by kevans: URL: https://cgit.FreeBSD.org/src/commit/?id=41aa44d0b2b658ab9a560fa325a323ed616c7ecf commit 41aa44d0b2b658ab9a560fa325a323ed616c7ecf Author: Kyle Evans <kevans@FreeBSD.org> AuthorDate: 2025-08-08 04:52:53 +0000 Commit: Kyle Evans <kevans@FreeBSD.org> CommitDate: 2026-04-12 13:43:35 +0000 grep: toss in some explicit fflush() grep|tee of the src/ tree for infrequently-occurring strings is fairly annoying; drop some tactical flushes at line-match boundaries to reduce the long stalls. In the case of `grep -o`, we'll flush after multiple lines if there are multiple matches within a single line of text, while for non`-o` we'll flush generally after every line.
