Hi Guys,
I want to add this logic to my existing Unix code.How to append the changes to my input file (valar.csv ) in place .

I tried creating a tmp file:

TMPFILE=${sourceDN}/tmp.csv

awk -F, '
NR==1   {next}
{$1=$1; print}
{$3 = $3 "D"; $11 = 3; $19 = ($19==1?2:1);$13 = $14 = $15 = $25  $28 = "Y"}
1' OFS=, ${inputFile} > ${TMPFILE}
mv ${TMPFILE} ${inputFile}

I am getting this error:

syntax error The source line is 4.
 The error context is
                {$3 = $3 "D"; $11 = 3; $19 = ($19==1?2:1);$13 = $14 = $15 = $25  $28 >>>  = <<<  "Y"}
 awk: The statement cannot be correctly parsed.
 The source line is 4.
