如何读取所有行元素以及标题名称？

Question

这是我的工作测试文件

Name  Column1  Column2  Column3  Column4
Dir01  val1     val2     val3     val4     
Dir01  val5     val6     val7     val8     
Dir01  val9     val10    val11    val12

我想要的输出是这样的

for loop over row elements
For Dir01
        Column1 = val1
        Column2 = val2
        Column3 = val3
        Column4 = val4

For Dir02 
        Column1 = val5
        Column2 = val6
        Column3 = val7
        Column4 = val8
For Dir03 
        Column1 = val9
        Column2 = val10
        Column3 = val11
        Column4 = val12
done

Answer 1

awk '
    NR==1{split($0,h); next} 
    {print "For " $1; for(i=2;i<=NF;i++) printf "\t%s = %s\n", h[i], $i}
' file
For Dir01
    Column1 = val1
    Column2 = val2
    Column3 = val3
    Column4 = val4
For Dir01
    Column1 = val5
    Column2 = val6
    Column3 = val7
    Column4 = val8
For Dir01
    Column1 = val9
    Column2 = val10
    Column3 = val11
    Column4 = val12
