I’d classify basic search/replace functionality of sed as “basic” - you see such scripts frequently enough in shell scripts. Same for awk and “extract fields 1 and 3”. Anything beyond that quickly escalates into intermediate and advanced usages. Often you can find an SO post for lots of intermediate usages (where you can just include it as a link saying “I’m trying to do X”) but advanced usages that require knowledge of that are best avoided unless you are investing in sed/awk expertise in your team. Usually choosing something like Python, Ruby, Node or even Perl can provide better value because all of those languages can solve the same problem and solve other problems those tools can’t.
