Do either of these tools have a "grep" mode, so that I can alias grep to it and get similar, but improved, behavior? 25 years of habit is a lot of reinforcement to overcome and I'd love to just be able to take advantage of these tools with an alias. As is I just have a grep wrapping shell script to give it some sane defaults which works fairly well.

No, you're asking oranges to be bananas. Read the man page or user guide. It's not grep, it's better and already has saner defaults. https://github.com/BurntSushi/ripgrep/blob/master/GUIDE.md https://github.com/BurntSushi/ripgrep/blob/master/GUIDE.md

The closest I know of is `rg -uuu`. From the manual: > -u, --unrestricted ... > Reduce the level of "smart" searching. A single -u won't respect .gitignore (etc.) files. Two -u flags will additionally search hidden files and directories. Three -u flags will additionally search binary files. > rg -uuu is roughly equivalent to grep -r.

Yes, that's what I did for about ten years before I wrote ripgrep. :-) > Do either of these tools have a "grep" mode, so that I can alias grep to it and get similar, but improved, behavior? Another commenter already mentioned `rg -uuu`, and that's pretty much the right answer. In a large number of cases, if you `alias grep=rg`, then most things will continue to work as you expect. If you really do not want any kind of smart filtering, then yes, you'll want `alias grep="rg -uuu"`. But otherwise, things like `command ... | rg pattern` and `rg pattern file ...` will continue to work just like grep. ripgrep also tries to use the same names for flags as grep, wherever possible. So you'll find a lot of overlap there too. Please note that ripgrep is not and is not intended to be a drop-in replacement. But I didn't go out of my way to be incompatible with grep either. So a lot of it should be quite familiar!
