file as input for script
how do I use a file (comma seperated) as an input for a script in bin/sh?
e.g.
I have a script that :
Input1=$1
Input2=$2
Input3=$3
Input4=$4
echo "$Input1, $Input2, $Input3,$Input4" (or some other function)
If I have a .csv file which lists many rows of input:
joe,5,john,10
pat,77,tim,88
etc... (Input1,Input2,Input3,Input4)
How do I use this file for the input of what ever I make the script do? The input will be changed frequently, so I would like to just edit the .csv file, and have the script update the info.
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.
