Question

我有一个数据列表如下：

Account Number: 11111
Domain        : domain.com
     Quantity: 1
     Quantity: 2
    Processor: Intel Xeon E5-1650 V2 3.5GHZ, Hexa Core
    SERVERCHASSIS: Standard - Single PSU - No Hot Swap Bays

Account Number: 54321
Domain        : domain0.com
     Quantity: 1
    Processor: Intel Xeon E3-1240 V1 3.3Ghz, Quad Core
    SERVERCHASSIS: Standard - Single PSU - No Hot Swap Bays
     Quantity: 1

Account Number: 12345
Domain        : domain1.com
     Quantity: 1

我想使用sed / awk删除下一行中未跟随“Processor：”的“Quantity：X”的所有条目。如果以下行不包含“Quantity：X”和“Processor：”，我还想删除“帐号：XXXXX”和“域：”行。这反过来会将上述数据更改为：

Account Number: 11111
Domain        : domain.com
     Quantity: 2
    Processor: Intel Xeon E5-1650 V2 3.5GHZ, Hexa Core
    SERVERCHASSIS: Standard - Single PSU - No Hot Swap Bays

Account Number: 54321
Domain        : domain0.com
     Quantity: 1
    Processor: Intel Xeon E3-1240 V1 3.3Ghz, Quad Core
    SERVERCHASSIS: Standard - Single PSU - No Hot Swap Bays

任何人都可以使用sed或awk或两者的组合提供完成此任务的方法吗？

Answer 1

$ cat tst.awk
BEGIN{ RS=""; FS="\n" }
/Quantity:/ && /Processor:/ {
    for (i=1; i<=NF; i++) {
        if ( ! (($i ~ /Quantity:/) && ($(i+1) !~ /Processor:/)) ) {
            print $i
        }
    }
    print ""
}
$ 
$ awk -f tst.awk file

Answer 2

编辑：错误......在回答之前应该已经阅读了问题这个应该有用，希望

BEGIN { 
        OFS=RS
        FS="\n"
        RS= ""
    }

    {
        selected = 0
        drop = 0
        for (i = 1; i <= NF ; i++)
        {
            if ($i ~ "Quantity:")
            {
                if ($(i+1) ~ "Processor:") selected = 1
                else  drop++
            }
            $i = $(i+drop)
        }
        if (selected) print
    }

CMD

gawk -f processor.awk processor.txt

输出

Account Number: 11111
Domain        : domain.com
     Quantity: 2
    Processor: Intel Xeon E5-1650 V2 3.5GHZ, Hexa Core
    SERVERCHASSIS: Standard - Single PSU - No Hot Swap Bays

Account Number: 54321
Domain        : domain0.com
     Quantity: 1
    Processor: Intel Xeon E3-1240 V1 3.3Ghz, Quad Core
    SERVERCHASSIS: Standard - Single PSU - No Hot Swap Bays

如果以下行不匹配，请使用sed / awk删除一行
