Sorry for leading you towards misunderstanding...
Please consider the below 3 sample files:

file1.csv
C01;10
C02;0
C03;0
C04;0
C05;20
C06;0
C07;0
C08;0

file2.csv
C01;50
C02;20
C03;90
C04;0
C05;0
C06;0
C07;40
C08;0


file3.csv
C01;0
C02;0
C03;0
C04;10
C05;30
C06;80
C07;40
C08;60

Then the resultant output file should be as follows:

output.csv
C01;60
C02;20
C03;90
C04;10
C05;50
C06;80
C07;80
C08;60

One more thing is that, I am writing a perl script and not a shell script. hence I cannot use the line "perl -F';' -lane'" (If Iam not wrong).
Please guide me...

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. SEE ALSO
