Subject: [PATCH v2 5/6] selftests: net: Use "grep -E" instead of "egrep"
Date:   Wed, 23 Nov 2022 09:03:32 +0800
Message-Id: <1669165413-12035-6-git-send-email-yangtiezhu@loongson.cn>
In-Reply-To: <1669165413-12035-1-git-send-email-yangtiezhu@loongson.cn>

Precedence: bulk

The latest version of grep claims the egrep is now obsolete so the build
now contains warnings that look like:
	egrep: warning: egrep is obsolescent; using grep -E
fix this up by moving the related file to use "grep -E" instead.

  sed -i "s/egrep/grep -E/g" `grep egrep -rwl tools/testing/selftests/net`

Here are the steps to install the latest grep:

  wget http://ftp.gnu.org/gnu/grep/grep-3.8.tar.gz
  tar xf grep-3.8.tar.gz
  cd grep-3.8 && ./configure && make
  sudo make install
  export PATH=/usr/local/bin:$PATH
