[MacOS] 터미널 명령어 모음



2021. 2. 11. 20:18


맥을 사용하다 보면 필연적으로 터미널을 사용해야 할 상황이 발생한다. 하지만 GUI에 길들여져 있던지라 까만 배경에 흰 글자 몇 개는 굉장히 당혹스럽기도 하고 그나마 몇 번 써본 윈도의 CMD와도 명령어가 달라 난해하다. 그래서 터미널 명령어를 찾아보게 되었고 자주 사용하는 cd(Change Directory), rm(Remove), mkdir(Make Directory) 외에 여러 명령어가 소개된 해외 자료가 있어 가져와 보았다. 출처는 하단에 표기되어 있다.
