Ask HN: Instant realtime grep tool for Linux

[leakbang]

I have been searching for an instant, real-time grep tool to search through source code on Linux but I haven't found any application that does this.

I have only found ONE ancient app only available on Windows, called Baregrep.

Is there any app like this but also available for Linux?

Ripgrep? Or are you looking for something with an UI also?

From what I could tell by looking at ripgrep's github page, it works exactly the same as grep. So it is not real-time as I type, search.
