Require original field position after sorting the values in a record
Dear Team,

Can any body help me out to get the filed position of the records post sorting using AWK programming.

Thanks in advance

Example Input:
Code:
StudentID   col-1   col-2   col-3   col-4       
1234   14   10   12   13       
1235   10   11   12   13       
1236   13   12   11   10       
2345   20   30   10   50       
2346   20   21   24   23       
2347   14   14   13   12       
3312   10   11   10   12       
3313   15   16   17   15

Example Output:
Code:
1234   2   3   4   1       
1235   1   2   3   4       
1236   4   3   2   1       
2345   3   1   2   4       
2346   1   2   4   3       
2347   4   3   1   2       
3312   1   3   2   4       
3313   1   4   2   3

I have an array in which I would require original position of the value post sorting.

Below is simple script which I written using asort function to get the values sorted, but I need output as initial array original filed position after sorting.


-bash-3.2$ awk 'BEGIN {a[1]=1234; a[2]=14; a[3]=10; a[4]=12; a[5]=13; n=asort(a,dest); for (i=1;i<=n;i++) { printf("%s,", dest[i])}}'
10,12,13,14,1234,-bash-3.2$
-bash-3.2$

Excepted :
3,4,5,2,1

Try this

Code:
 $ cat test.sh
#!/bin/bash

echo | \
awk '
    function keys(arr,key){
                           for(z in arr){if(arr[z]==key)return z}
                           return "Not Found"
                          }
BEGIN {
           OFS="\t"
           a[1]=1234
           a[2]=14 
           a[3]=10 
           a[4]=12 
           a[5]=13 

    n=asort(a,dest)

    for(i=1;i<=n;++i)
                    printf "Value ----->" OFS dest[i] OFS "Original Index---->"OFS keys(a,dest[i]) RS
      }'

resulting
Code:
$ sh test.sh 
Value ----->    10    Original Index---->    3
Value ----->    12    Original Index---->    4
Value ----->    13    Original Index---->    5
Value ----->    14    Original Index---->    2
Value ----->    1234  Original Index---->    1
