如何使用命令 IOSTAT -DlR 1 2

Question

输入：

#iostat -DlR 1 2

输出：

root@myserver #iostat -DlR 1 2

System configuration: lcpu=20 drives=2 paths=16 vdisks=0

Disks:                      xfers                                read                                write                                  queue

期望的输出：

hdisk0    77.8k   19.0      0.0      77.8K

我想要想要的输出。

HEADER='Device      bps     tps     bread     bwrtn'
HEADERIZE="BEGIN {print \"$HEADER\"}"
PRINTF='{printf "%s  %s  %s  %s  %s  %s  %s  %s\n", device, bps, tps, bread, bwrtn}'
CMD='iostat -DlR 1 2'
FILTER='/^cd/ {next} /^Disks:/ {reportOrd++; next} (reportOrd<2) {next}'
FORMAT='{device=; bps="2"; tps="3"; bread=; bwrtn=}'

$CMD | tee $TEE_DEST | awk "$HEADERIZE $FILTER $FORMAT $PRINTF"  header="$HEADER"

当我运行上面的命令时，我得到的是这个（这不是我想要的输出：

root@myserver #$CMD | tee $TEE_DEST | awk "$HEADERIZE $FILTER $FORMAT $PRINTF"  header="$HEADER"
Device      bps     tps     bread     bwrtn

Answer 1

$ awk '
    !NF { f=0 }
    =="%tm" { if (!cnt++) print "Device", , , , ; f=1 }
    f && /^[^[:space:]]/ { print , , , ,  }
