How to allow wget to overwrite files
wget 덮어쓰기
wget 중복 방지

1 문제상황[ | ]

wget은 파일이 이미 있는 경우 .1 .2 확장자를 붙인 별도의 파일로 다운로드된다.
따라서 중복 수행시 받은 파일이 여러 개가 된다.

예시

2 방법 1: -O 옵션[ | ]

위치를 지정해주면 덮어쓰기된다.

wget URL주소 -O /디렉토리/파일명

wget http://example.zetawiki.com/txt/utf8test.txt -O /tmp/utf8test.txt

3 방법 2: -N 옵션[ | ]

덮어쓰기는 아니고 같은 파일이라면 받지 않음

명령어

wget -N URL주소
