Given that both grep and find are weird/inconsistent between BSD/GNU versions, and I typically use them piped together for the same things anyway, I’ve found that ripgrep is a nice/faster/universal alternative that is pretty unproblematic to install in whatever environment I want: https://github.com/BurntSushi/ripgrep

And also fd https://github.com/sharkdp/fd

But isnt that what AI is for? Writing syntactically correct regexes?
