It would help to know what Operating System and Shell you have.
Many versions of "ping" default to "continuous ping" and never finish.
In my version the parameter "-n 3" will try three times, yours may be different.
Shell code is for most Bourne-like shells such as: sh, ksh, bash and Posix. Some would replace "cat" with an inward redirect if that shell will allow it.

Specifically on RHEL 5.7.
When does the underlying ksh process open and close files? Every time they're accessed, or as little as possible?

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.
