왜 만들었나? 한방에 압축할려다 gzip 이 700~1000 mb 사이에서
죽어버리기 때문에, du 로 뒤지면서 작업했더니 부분 복구할때 무지
귀찮아서.
파일이 너무 쪼개져서 ftp 로 전송시 시간이 너무 많이 걸릴수 있다?
!!인정합니다.
아직까지 생각으론 dir-list 파일을보고 파일 번호 가 몇번인지 보고
그파일 찾아서 복구해야함.
파일이름에 full-path 를 넣거나 md5sum을 넣는 방법도 있으나 파일 보기가 더 힘들어질까봐 하지않음.
암튼 심심해서 만들어본거구요 <스톤형님 Jag의 허접 스크립 꼴보기싫음
지우시길 >
____ 스크립트 이해가 잘 안가실꺼에요 복잡하게 짜서리 뭔가 질문있다?
메일 보고 내키면 답멜 드리죠.
리눅스가 좋아....
