Subject: [PATCH v2 1/2] egrep, fgrep: deprecated
Date:   Tue, 20 Sep 2022 11:19:50 +0800
Message-Id: <20220920031951.2098839-1-jencce.kernel@gmail.com>
X-Mailer: git-send-email 2.31.1
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk
List-ID: <fstests.vger.kernel.org>
X-Mailing-List: fstests@vger.kernel.org

Since this grep commit:
	commit a9515624709865d480e3142fd959bccd1c9372d1
	Author: Paul Eggert <eggert@cs.ucla.edu>
	Date:   Sun Aug 15 10:52:13 2021 -0700

	    egrep, fgrep: now obsolete

egrep will trigger a warning like:
	+egrep: warning: egrep is obsolescent; using grep -E

This will break many gold output.
