pupEDIT3: 또한 and의 조합을 시도했지만 jq날짜와 크기가 배열에 없는 것 같아서 구문 분석하기가 쉽지 않습니다.

더 쉽고 "더 깨끗한" 방법은 없을까요?

답변1

다음을 사용하여 파일 크기를 바이트로 변환합니다 numfmt --from=.... 그런 다음 쉽게 요약할 수 있습니다.

curl -s $URL | html2text -width $COLUMNS \
| awk '$3~/\.mp4/{print $6}' \
| LC_ALL=C numfmt --from=iec \
| paste -sd+ | bc

58044134197
  • | numfmt --to=iec사람이 읽을 수 있는 크기를 다시 얻으려면 추가하고 --format '%.1f'소수점 이하 자릿수를 얻으려면 추가하십시오.
  • --from=si파일 크기는 1000을 기준으로 합니다 .
  • 로컬 설정에 따라 생략할 수 있지만 LC_ALL=C오류가 발생합니다 1.1G.

답변2

이 시도,

cat file | awk '{($NF ~ /G/)?$NF=$NF*1024:$NF=$NF*1} {sum += $NF} END {print sum}'
  • 마지막 필드에 1이 있으면 1024를 곱합니다.G
  • 그렇지 않은 경우 1을 곱합니다(M을 제거하기 위해 K 등이 있는 경우 주의해야 함).
  • 마지막으로 마지막 필드에 있는 모든 값의 합계입니다.

마지막 필드가 아니라 6번째 필드라고 언급했으므로 NF를 6으로 바꿀 수도 있습니다.
