refactor: use grep -E/-F instead of fgrep/egrep

`egrep` and `fgrep` are obsolescent now. This PR updates  all `egrep` and `fgrep` commands to `grep -E` and `grep -F`.

Running egrep/fgrep command with grep v3.8 will output the following warning to stderr:

```
egrep: warning: egrep is obsolescent; using grep -E
```
