From 2b521630f93b79fc8cbe0fd63fb22879a11b5024 Mon Sep 17 00:00:00 2001 From: Eric Sunshine Date: Thu, 22 Sep 2022 00:18:25 +0000 Subject: [PATCH] check-non-portable-shell: detect obsolescent egrep/fgrep GNU grep deprecated `egrep` and `fgrep` with release 2.5.3 in 2007. As of release 3.8 in 2022, those commands warn[1] that they are obsolescent. Now that all the Git test scripts have been scrubbed of uses of `egrep` and `fgrep`, make `check-non-portable-shell` complain about them to prevent new instances from creeping back into the project.
