Hey @tbhaxor !!

Looks like you may have missed the existing discussion on the issue:

• [Bug]: "egrep: warning: egrep is obsolescent" #2163

And my (nearly approved for merge) Pull Request:

• chore: Use grep -E / grep -F instead of egrep / fgrep #2164

Also, another PR that came in after mine:

• Replace egrep with grep -E #2167

A quick glance suggests my PR contains these changes, and a few more, but it would be great if you could take a once-over of mine and confirm.

Thanks!
