커밋 ID 양식 git 목록을 생성하는 스크립트를 만들려고했습니다.쉘 스크립트 루프 내에서 awk를 사용할 때 변수가 업데이트되지 않습니다
START_INDEX=0
while [ ${START_INDEX} -lt ${#VERSION_ARRAY[@]} ]
do
CURRENT_COMMIT_LINE=$(some code)
NEXT_COMMIT_LINE=$(some code)
COMMIT_SHA_ARRAY[${START_INDEX}]=$(git log master | \
awk -v start_line=${CURRENT_COMMIT_LINE}\
-v end_line=${NEXT_COMMIT_LINE}\
'NR == start_line, NR == end_line {if(match($0, "commit")) print $2}')
START_INDEX=$((START_INDEX+1))
done
변수 "start_line"및 "end_line"은 업데이트되지 않습니다. "CURRENT_COMMIT_LINE"및 "NEXT_COMMIT_LINE"을 에코하려고했는데 루프 프로세스를 통해 업데이트되었습니다. 내가 잘못 했는가?

글쎄, 내가 존재하지 않는 변수를 사용하는 디버깅 메시지에서 실수를 저질렀습니다. 그래서 나는 계속 같은 SHA를 얻었다. 하지만 BEGIN 내부에 start_line 및 end_line 변수를 인쇄합니다. 나는 항상 같은 결과를 얻는다. 그것에도 불구하고, 나는 정확한 SHA를 얻는다. – user2817665
