Subject: [PATCH] perf tools: Use "grep -F" instead of "fgrep"
Date:   Fri, 16 Jun 2023 09:56:07 +0800
Message-Id: <1686880567-30017-1-git-send-email-yangtiezhu@loongson.cn>
Precedence: bulk

There exists the following warning when execute perf test
record+probe_libc_inet_pton.sh:

  fgrep: warning: fgrep is obsolescent; using grep -F

This is tested on Fedora 38, the version of grep is 3.8,
the latest version of grep claims the fgrep is obsolete,
use "grep -F" instead of "fgrep" to silence the warning.
