ripgrep

Ripgrep is a grep alternative.

The (only) reason I use ripgrep (at least for now) is because it has a much nicer output by default (it also has colors, but you can’t see it below):

Compare this to grep’s default output:

Flags I use

-i / --ignore-case
-v / --invert-match

That’s mostly it.

pacman ripgrep-all
