서버 작업하면 가끔 콘솔 2개 열고 작업하다 엉뚱한데 날리는 경우가 있습니다.
특히나 꾸벅 꾸벅 졸면서 새벽작업할때.. 캄캄합니다. IDC까지 그새벽에 가야하고..
우선 쉘스크립트 입니다.( 퍼온 자료입니다. 출처는 노트북에 있는데 가방열고 켜서 즐겨찾기 확인하기가 귀찮네요.)
cat newrm.sh
#!/bin/sh
# newrm - a replacement for the existing rm command that allows a
# rudimentary unremove capability through utilizing a newly created
# directory in the user's home directory. It can handle directories
# of content as well as individual files, and if the user specifies
# the -f flag, files are NOT archived, but removed.
# rewrm 에서 -f를 붙이면 휴지통으로 버리지않고 완전 제거한다는...
# Big Important Warning: you'll want a cron job or similar to keep the
# individual trash directories tamed, otherwise nothing will ever
# actually be deleted on the system and you'll run out of disk space!

본인계정의
.profile에 alias rm='/root/newrm.sh' 추가후
source .profile 리로드
사용 rm 파일명하면 다짜고짜 지워버립니다.
단 본인 HomeDir/.deleted-files 에 보면 지워진 파일이 들어있습니다....
수동으로 꺼내서 이름을 변경하셔도 되구요..
아래의 파을을 이용하면 됩니다. 윈도그로 따지면 휴지통에서 복원정도 명령이겠네요.

휴지통에서 복구하기..
unrm.sh 복구할 파일명하면 됩니다.
꼭 필요하던건데.. 이번에 책을 보면서 알게되어 저자의 사이트에서 퍼와서 테스트후
작성합니다.
책명 : 셸 스크립트 101가지 예제로 정복하는 - 에이콘출판사
광고라고 혹시 하실분 계실까 몰라서 인데 제가 22,500원주고 모 사이트에서 사서 본책입니다.
원저자는 외국인 인듯합니다.
그럼 머리가 캄캄해 지지 않도록 노력해 봅시다.
