Hi Rudi,

I have tried like below. Now the output is not displaying to teh screen but Output1 and output2 are generated with 56 lines input data as 1 line without modification on 19th field.

Code:
nawk '
       FNR == 1 {
              if(NR>1)
              close(ofn)
              ofn = "output" ++nf
       }
               {CNF = (length()-10)/7
                printf "%9s", substr ($0, 1, 9) > ofn
                for (i=0; i<=CNF; i++) T[i+2] = substr ($0, 10+i*7, 7)
               TMP = 100 - (T[8] + T[9] + T[10] + T[11] + T[12] + T[13] + T[14] + T[15] + T[16] + T[17] + T[18])
       for (i=2; i<=CNF+2; i++){printf "%7s", T[i] > ofn} if(i==18) {printf "%7.3f",T[i]=TMP > ofn}
      }
      ' input1 input2

Please suggest me on this.

Where has the
Code:
           { print > ofn
          }

gone? And, was the output correct when it occurred on the screen?

Hi Rudi,

I have tried with print > ofn. Then the outputs are generated as below:

Code:
032016501  3.974 96.026 20.605 28.838 21.722 28.835  0.306  0.000 66.204  0.229  0.000 16.707  5.348  0.000  3.142  0.000  5.929 71.299 28.701  6.662 93.338  2.360 97.640  0.000100.000 46.620 53.380 43.192 56.808 66.447 16.775  0.063  0.160 16.554 92.911  1.882  0.159  5.048032016501  3.974 96.026 20.605 28.838 21.722 28.835  0.306  0.000 66.204  0.229  0.000 16.707  5.348  0.000  3.142  0.000  5.929 71.299 28.701  6.662 93.338  2.360 97.640  0.000100.000 46.620 53.380 43.192 56.808 66.447 16.775  0.063  0.160 16.554 92.911  1.882  0.159  5.048

Each line in output is repeating twice and 19th field modification did not happen

I tried with printf > ofn. All the 56 lines merged as 1 line in the output.

Also tried with printf RS > ofn. Outputs generated are same as the inputs.

The output is not correct when it printed on the screen.its same like input.19th field modification did not reflect.

I am missing some where to take the modification done on 19th field. Please suggest me on this.

Thanks in advance,

Use printf RS > ofn or print "" > ofn.

Where does
Code:
       for (i=2; i<=CNF+2; i++){printf "%7s", T[i] > ofn} if(i==18) {printf "%7.3f",T[i]=TMP > ofn}
                                                        ^--- this   ^--- and this

come from, when the working solution had
Code:
for (i=2; i<=CNF+2; i++){printf "%7s", T[i]; if(i==18) {printf "%7.3f",T[i]=TMP}}

You NEED to learn to do careful one-to-one copies, and, if modifying proposals, to know EXACTLY what you are doing!

And, don't rely on being spoon fed in these fora for every problem occurring in your IT career.

Rudi, as per your suggestions , i have modified the first code below


for (i=2; i<=CNF+2; i++){printf "%7s", T[i]; if(i==18) {printf "%7.3f",T[i]=TMP}}

as

for (i=2; i<=CNF+2; i++){printf "%7s", T[i] > ofn} if(i==18) {printf "%7.3f",T[i]=TMP > ofn}


I have tried printf RS > ofn and print "" > ofn .In all of the trails ,the modification done on 19th field is not reflecting in the output.

Thanks for all of your suggestions.

Sorry, is it working now, or failing?

Hi Rudi,

In both the cases printf RS > ofn and print "" > ofn, I am getting the outputs as same as inputs . The arithmetic operation which i performed on 19th field is not reflecting in my outputs. So there is no difference between my Input and Output.

I am missing somewhere to take that arithmetic operation(done on 19th field) result to reflect in my output.

The same code when i am applying it on only one file, its perfectly working.

Code:
nawk '
               {CNF = (length()-10)/7
                printf "%9s", substr ($0, 1, 9)
                for (i=0; i<=CNF; i++) T[i+2] = substr ($0, 10+i*7, 7)
                TMP = 100 - (T[8] + T[9] + T[10] + T[11] + T[12] + T[13] + T[14] + T[15] + T[16] + T[17] + T[18])
        for (i=2; i<=CNF+2; i++){printf "%7s", T[i]; if(i==18) {printf "%7.3f",T[i]=TMP}}
              printf RS
       }
       ' input > output

TMP values(19th field) are not reflecting when i am applying the code on multiple files and taking results to multiple files a sbelow

Code:
nawk '
       FNR == 1 {
              if(NR>1)
              close(ofn)
              ofn = "output" ++nf
       }
               {CNF = (length()-10)/7
                printf "%9s", substr ($0, 1, 9) > ofn
                for (i=0; i<=CNF; i++) T[i+2] = substr ($0, 10+i*7, 7)
               TMP = 100 - (T[8] + T[9] + T[10] + T[11] + T[12] + T[13] + T[14] + T[15] + T[16] + T[17] + T[18])
               for (i=2; i<=CNF+2; i++){printf "%7s", T[i] > ofn} if(i==18) {printf "%7.3f",T[i]=TMP > ofn}
      }{printf RS > ofn
      }
      ' input1 input2

Please advise.
