grep을 쓰다가 속도가 너무 느린 것 같아, 찾다보니 ripgrep이라는 패키지가 있어 공유한다.
명령 예시는 rg <찾고자 하는 내용> 식이고, 옵션은 링크를 참고하자.
grep할 일이 많다면 강력추천하는 툴이다.
(It seems that the speed is too slow while using grep, so there is a package called rip grep so I share it.
An example of the command is the rg <What you want to find> expression, and see the link for options.
It is a highly recommended tool if you have a lot of grep to do.)
