I have written above awk under for loop so that this column_no get incremented everytime, so that it picks up different colum for each iteration. [[ and also out_file_name variable get changed in each iteration]]
when i execute this, I get output as
File 1:
col1~~col2~~3 <== prints number "3" instead of picking thrid column value from the input file.
[[ Same thing for all the files ]]
Am i overlooking awk to achieve my request? Pls correct me if doing something wrong or sytax problem.
I knew it can be achieved by writting 4times. But my actual case it is more than 12. So thought of writting professional way, to handle all possible cases.
