Seems this project predates ugrep and has a nicer interface.

Both projects were started around the same time in 2019. The initial git commits were about five weeks apart:

https://github.com/Genivia/ugrep/commit/e37c986dd842adc3b2c2...

https://github.com/phiresky/ripgrep-all/commit/16b4277d361ce...

Wow! That's interesting.

Rip greps GitHub readme shows clearly superior performance to ugrep

C++ & autotools. No, thanks.

Or: apt-get install ugrep
