I'm new to PowerShell and I'm trying to export event logs from different machines to a CSV file. The problem I'm facing is that every time I export, it overwrites the existing data in the CSV instead of adding new entries. I'm sure there must be a way to append the new data instead of replacing the old. Any suggestions?

If you're looking to keep the existing file but still need to add new logs, try using `Add-Content`. It helps in appending data to your CSV files. It's a handy trick!
You can use the `-Append` parameter with the `Export-CSV` command to add to your existing CSV file instead of overwriting it. Check out the official PowerShell documentation for more details!
To avoid overwriting, you might want to generate unique filenames using a timestamp with `Get-Date`. That way, each export creates a new file instead of replacing the previous one. Just a thought!
That's a great idea! Using timestamps can keep your exports organized and prevent any loss of data.
