내 변수는 다음과 같습니다.
HEADER='Device bps tps bread bwrtn'
HEADERIZE="BEGIN {print \"$HEADER\"}"
PRINTF='{printf "%-10s %11s %11s %12s %12s %13s %13s %13s\n", device, bps, tps, bread, bwrtn}'
CMD='iostat -DlR 1 2'
FILTER='/^cd/ {next} /^Disks:/ {reportOrd++; next} (reportOrd<2) {next}'
FORMAT='{device=$1; bps="?"; tps="?"; bread=$5; bwrtn=$6}'
$CMD | awk "$HEADERIZE $FILTER $FORMAT $PRINTF" header="$HEADER"
출력이 다음과 같기를 원합니다.
Device bps tps bread bwrtn
hdisk0 0.0 0.0 0.0 0.0
hdisk1 0.0 0.0 0.0 0.0
hdisk2 0.0 0.0 0.0 0.0
hdisk3 0.0 0.0 0.0 0.0
물론 더 많은 성능 헤더를 원했지만 단순하게 유지하려고 노력했습니다.
다음을 실행할 때 문제가 발생합니다 $CMD | awk "$HEADERIZE $FILTER $FORMAT $PRINTF" header="$HEADER". 결과는 다음과 같습니다.
Device bps tps bread bwrtn
--------------- ? ? --------------------------------------
%tm ? ? bwrtn rps
act ? ? outs serv
hdisk1 ? ? 0.0 0.0
hdisk0 ? ? 0.0 0.0
변수 "FILTER"가 잘못된 것 같지만 올바른 구문을 모릅니다.
입력은 다음과 같습니다.iostat -DlR 1 2

논평:
일을 너무 복잡하게 만드는 것 같아 걱정됩니다. 제공된 솔루션은 입력 샘플과 원하는 출력을 기반으로 한 추측이며 일부 불일치가 있습니다. hdisk2데이터 및 의 출처 hdisk3가 입력에 없으므로 설명해주세요 . 또한 코드를 여러 환경 변수로 분할하는 복잡한 솔루션을 구축하는 이유도 설명해주세요.
