From fe56c745b8cb562445b318bacbb4267f07e43584 Mon Sep 17 00:00:00 2001 From: Jan Beich Date: Sun, 12 Mar 2017 03:19:14 +0000 Subject: [PATCH] Convert sed(1) syntax to be compatible with FreeBSD and OpenBSD BSD regex library doesn't support extended RE escapes (e.g. \+) and shorthand character classes (e.g. \s, \S) and SVR4-style word delimiters[1] (on DragonFly and NetBSD). Both GNU and BSD sed support -E and -r to enable extended RE but OS X still lacks -r.
