I think the point was, she wasn't trying to replace sed/grep. She had a script which she wrote and got some benefit from and decided, why not, post it on github. That said, I'm glad at least someone stuck to their opinion. I don't see the problem in criticizing the utility of software. Sure, we should all be nice, but that doesn't mean we can't be critical. How many people defending her have left negative comments on Show HN posts? Also, if you thought she made sed/grep worse, wait till you see my frankenstein: https://github.com/hollingsworthd/POSIXplorer https://github.com/hollingsworthd/POSIXplorer
