In the part you snipped, I quoted the OP as saying:

I suppose I should've emphasised the "need" part more. Of course I agree that
sed can do some things more easily than awk but I don't think I've ever piped
them together and I don't expect I'll ever need to. Not to say I wouldn't do it
if appropriate for a quick-and-easy hack. In any case, I was really contrasting
the abilites of awk vs perl in this context rather than contrasting sed vs awk.

Good to know, though I've never used it in sed either. I'm more of a "tr" guy...
