Mac OSX 에서 압축한 것들을 다른 플랫폼에서 압축 해제할 때, ._ 파일들이 생성될 때가 있다.

이 때에는 아래와 같은 방법으로 해결할 수 있다.

 

 

1) OS X 설정 

OS X's tar also knows how to convert the ._ members back to native formats, but the ._ files are usually kept when archives are extracted on other platforms. You can tell tar to not include the metadata by setting COPYFILE_DISABLE to some value:

> COPYFILE_DISABLE=1 tar -cf 2.tar file*  

Or, you can insert the lines below in the .bash_profile:

# turn off special handling of ._* files in tar, etc.

COPYFILE_DISABLE=1; export COPYFILE_DISABLE

 

2) 이미 만들어진 압축파일을 열었을때 생성된 ._ 파일들 제거하기

> find . -type f -name '._*' -delete
