@leghorn, You have not made it "2013-08-07","02:01:50" bold. What is the logic on which you need to extract the date and time fields?

Hi
yeah I did not,becoz they are not needed
please see that there are 11 fields in the first line .. "CLLI","SWREL" ...
corresponding to these there are values in the next line ..
so the value of IVALDATE is 2013-08-07 and so on ..
these fields are always on the 8th,9th and 10th tabs
I need the values of "IVALDATE","IVALSTART" and "IVALEND"

Two options, if the index is same (8th 9th and 10th) and the required values are in the 2nd line

Code:
awk -F, 'NR==2{gsub(/\"/,x);print $8,$9,$10}' file.csv

More generic one would be similar to the one posted on the other thread Perl to shell script - The UNIX and Linux Forums

Code:
awk -F, 'NR==1{gsub(/\"/,x);for(i=1;i<=NF;i++){a[i]=$i;};getline;gsub(/\"/,x);for(i=1;i<=NF;i++){array[a[i]]=$i}} END{print array["IVALDATE"],array["IVALSTART"],array["IVALEND"]}' file.csv
