How is GNU / BSD sed and awk not awesome?
Limited regex capabilities. A fast tool that does what sed and awk do with PCRE2 would be amazing.
Well, I would like to tackle that but unfortunately I do not have enough time to do things for free. :(
Is there any demand for it anyway?
I think there would be, but I can only raise my own hand :-)
A tool called sd exists that's close enough for sed, but I haven't seen anything similar for awk.
