Commit Message

Tiezhu Yang June 16, 2023, 1:56 a.m. UTC 
  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the latest version of grep claims the fgrep is obsolete,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.
