Script for extracting data from csv file based on column values.

Hi all,

I am new to shell script.I need your help to write a shell script.
I need to write a shell script to extract data from a .csv file where columns are ',' separated.
The file has 5 columns having values say column 1,column 2.....column 5 as below along with their valuesm.
ref_num,Account Number,Misc, error 1,error 2
Code:
COD  , 121, misc, 0, 0
COD1, 123, misc2,1, 1

Now i want to write a script to first check if the file name.csv exists at /home/home1.
If the file exists i want to display column 1 to column 5 header along with their values only if the column error 1 or error 2 column has any other value than 0 i.e it should not have 0.

Output for above input should be like below:
Code:
ref_num:COD1
Account Number:123
Misc:misc2
error 1:1
error 2:1

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. SEE ALSO
