I completely understand. But I suppose most developers, specially in the USA (where salaries are astronomicals) and even Europe (where I am, most top-of-the-line laptops are affordable to most devs here) it's not a problem, but I too have a low-end Mac (which would be an expensive machine in some countries!) where IntelliJ doesn't run so well, as you mention. In those cases, I use emacs which has similar "grep" functionality. What I was arguing against was just doing it "only" in the CLI. You will spend hours for something that should be minutes!! But even the guy who originally said he does it on the CLI admited he's actually just calling it from the CLI, but using an IDE (if you allow me to call Neovim an IDE) to go through the results... which is basically the poor man way to do what IntelliJ does (no offence meant).
