스크립트를 사용한 Linux 자동화 [닫기]

스크립트는 확실히 더 잘 작성될 수 있지만, 무엇을 어디서, 무엇으로 추출할지, 어떤 소스에서 어떤 대상으로 연결할지 알지 못하면 더 나은 스크립트를 작성하기가 어렵습니다.

너할 수 없다경로 입력 시 약어(또는 등)를 사용하며 , $HOME실행 전 ~필수 입력 사항입니다 .chmod +x NameOfTheScript.sh

먼저 스크립트를 테스트하기 위해 tarball을 만드십시오!테스트 파일과 한 테스트 디렉터리에서 다른 디렉터리로 스크립트를 실행합니다. 예를 들어

# zip a test file
touch deleteme.txt
tar -czvf deleteme.tar.gz deleteme.txt

# create two test-dirs
mkdir -p {testdir1,testdir2}

- This script will let you extract an archive to a desired      \n
  location, and link one of the extracted files to a desired    \n
  location.                                                     \n

- Please be aware that entering absolute paths is usually       \n
  better when linking files, as this protects from path changes \n
  in the future.                                                \n

- If the file is in a subdir, you may provide the subdir, and   \n
  the file name, including its extension.                       \n
  Ex: mydir/myarchive.tar.gz                                    \n

- If the file is in a totally different dir, please provide the \n
