tree명령 없이 ls로 treeview로 보기(Treeview without tree command as ls)

개인적으로 시스템 취약점 분석 ~ 개인 리눅스 사용 모두 tree 명령을 굉장히 자주 사용합니다. 다만 간혹, tree가 없는 환경에서 treeview로 보고 싶은 경우가 있는데, ls, grep, sed 3개를 이용하면 tree와 비슷한 형태의 출력을 얻어낼 수 있습니다.

ls -R | grep ":$" | sed -e 's/:$//' -e 's/[^-][^\/]*\//--/g' -e 's/^/ /' -e 's/-/|/'

ls -R 옵션으로 하위 모든 파일을 출력
pipe로 grep에 넘겨 directory만 뽑아냅니다. (Directory만 볼 경우)
pipe로 sed로 넘겨 tree와 비슷하게 출력 포맷을 맞춰줍니다.

hbxss(https://github.com/hahwul/hbxss) 코드로 테스트해봅시다.
