영삼넷IT 강국 = 김영삼 블로그에 오신걸 환영합니다.

서버 작업하면 가끔 콘솔 2개 열고 작업하다 엉뚱한데 날리는 경우가 있습니다.
특히나 꾸벅 꾸벅 졸면서 새벽작업할때.. 캄캄합니다. IDC까지 그새벽에 가야하고..

쉘스크립트 입니다.

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.
