Protecting your csv files

proteggere i file con powershell

Richard Siddaway's Blog

I’m using csv files for this example but it applies to other types of file as well. Let’s produce a csv file:
Get-ChildItem -Path C:\Users\Richard\Documents -File |
select FullName, Length, LastWriteTime |
Export-Csv files.csv

This gives a small, useful set of data for the purposes of this post.
You can read the data back in:
Import-Csv .\files.csv

You have decided you need to keep a record of how these files are changing over time. You have further decided that you will create a csv file for each individual day you run the command. The individual files will carry the date as part of the name.
You can create the file name incorporating the date like this:
$file = “Files_$( (get-date -Format “s”).Split(“T”)[0]).csv”

Creating the csv file then becomes:
Get-ChildItem -Path C:\Users\Richard\Documents -File |
select FullName, Length, LastWriteTime |
Export-Csv $file

You can read the file using $file or its name
