awk : dynamic output flatfile filename

Hello,

I'm using the awk command to insert empty columns on a tab delimited flatfile - which works fine -
=> But I'm not able to manage dynamicaly the filename of the awk output based on the source flatfile filename

I have 3 source flatfile:
Code:
flatfile_Jan-2016.csv
flatfile_Feb-2016.csv
flatfile_Mar-2016.csv

And I would like to output the result of the awk command to
Code:
newflatfile_Jan-2016.csv
newflatfile_Feb-2016.csv
newflatfile_Mar-2016.csv

Below the awk command which is working for inserting empty columns but I'm not able to manage dynamically the target flatfile filename

Code:
awk -F"\t" '$6="\t" $6' OFS="\t" *flatfile* > flatfile_Jan-2016.dat


Thanks!

processcsv.py - process virt-top CSV files SUMMARY
virt-top --csv data.csv processcsv.py < data.csv DESCRIPTION
virt-top is a top(1)-like utility for showing stats of virtualized domains. processcsv.py is a simple Python script that post-processes the output of "virt-top --csv". It is used like this: virt-top --csv data.csv processcsv.py < data.csv The second command will overwrite the following files in the current directory: "global.csv" This contains the global (host) statistics columns from the CSV file. "domainNN.csv" (multiple files) For each libvirt domain ID NN, a file is created containing the per-domain statistics from the CSV file. SEE ALSO
