살려주세요~ 퇴근하고 싶어요 ㅠㅠ egrep 내에서 $변수를 사용할때 에러
글쓴이: help@osori.org / 작성시간: 월, 2007/10/29 - 6:36오후
안녕하세요 쉘스크립트를 짜던도중 에러에 막려 질문을 올립니다.
cat $FILENAME | grep "${DATE}" | grep "*CORRECT NEEDED*" | egrep '(${NOWDATE2}0[0-9]|${NOWDATE2}1[0-9])'돌리게 되면
egrep: 정규식 앞에 ?, * 또는 +가 올 수 없습니다.
나오네요...
shell 환경은 ksh 이고
OS는 HP-UX 입니다.
ksh이던 bash 든 별반 차이는 없을텐데..
참이를 어째야 하는지..
실제 소스와 실행 결과를 같이 올립니다.
참고로 이쉘은 매시 1-9분 20~29분 40~49분 에만 실행됩니다.
즉 20분 단위 결과를 처리하기 위함입니다.
쉘중 time.pl 과 time_1h.pl 은 시간값을 처리하기위한 단순한 perl로 신경쓰지 않으셔도 될듯 합니다.
20분 전의 시간값을 가져오는 perl

bash쉘에서 single quote를 쓰면서 variable을 쓰고 싶을때는

질문하신 내용과 상관없는 답이지만,
date --date='1 hours ago'
따위 명령으로 간단하게 시간을 가져올 수 있습니다.
