Gawk無法在3行之間找到最小值

Question

我有以下gawk腳本：

BEGIN{
    count = 0
    imp = ""
    time = 0
}

{

    if(count==0){
        imp = $0
        time = $7
        count = 1
    }

    else if(count==1 || count==2){

        if($7 < time){
            imp = $0
            time = $7
        }

            count+=1

    }

    else{
        count=0
        print imp
    }

}

和一堆這樣的文件：

[1,3]，[4,6]，[7,9]等行始終具有相同的$ 1，所有其他列均不同。 我希望整行都具有最后一列的最小值，並排除其他兩列，但是我現在執行的此腳本現在可以正常工作。

所以結果應該是：

1 57 0.850000 0.000010 0.725526 0.114805 0.610721
2 57 0.850000 0.000010 1.224136 0.063005 1.161131

提前致謝

Answer 1

根據您所討論的輸入和輸出示例，此一線工作：

awk 'NR%3==1{if(a)print a;a=$0;v=$NF;next}$NF<v{a=$0;v=$NF}END{print a}' file

Answer 2

更改：

else{
    count=0
    print imp
}

至：

else{
    print imp

    imp = $0
    time = $7
    count=1
}

我現在得到：
