내 의도는 itrpl_dsm_1_*.tif 파일에서 itrpl_dsm_1.tar.gz를 생성하는 것이었지만 분명히 내가 원하는 것을 달성하지 못했습니다.
답변1
${i}not 을 사용해야 합니다 $i. 즉
for (( i=1; i<=12; i++ )); do tar -czvf itrpl_dsm_$i.tar.gz itrpl_dsm_${i}_*.tif; done
bash는 name 변수를 찾았 i_지만 해당 이름을 가진 변수가 없으므로 아무것도 대체되지 않습니다.
따라서 패턴은 가 되고 itrpl_dsm_*.tif와일드 *카드는 확장되어 패턴과 일치하는 모든 파일로 대체됩니다.
