lets say there is file named file_name which have columns as follows.

Code:
ID GENE Newcol pos start end


Command is:
Code:
awk 'NR==1 {$2=$2 "\t""Newcol"; print; next}' file_name

Output should be:

Code:
ID GENE Newcol pos start end


So after running the command a newcol is being added. Bot sure if this may help you. Please get back to us in case you need more assistance for same.




Thanks,

processcsv.py

PROCESSCSV.PY(1)					      Virtualization Support						  PROCESSCSV.PY(1)

NAME

       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.
