Replace egrep with grep -E (#2618)

Browse Source 
Quoting the [release notes of gnu
`grep-3.8`](https://lists.gnu.org/archive/html/info-gnu/2022-09/msg00001.html)

>   The egrep and fgrep commands, which have been deprecated since
  release 2.5.3 (2007), now warn that they are obsolescent and should
  be replaced by grep -E and grep -F.

In order to fix the warning, I've replaced all instances of `egrep` with
`grep -E`
