E)  Combine Multiple CSV Files with PowerShell

A network engineer was tasked with reviewing extensive log files from switches and firewalls, and all had the same format but were all in separate files. They only cared about very specific data in these files (30+) and had to open and review each one on a quarterly basis. I decided to write a PowerShell Script to filter all the data and combine required reading to a single report (CSV).


Read-Host, Get-ChildItem, -match, Out-File, If, Foreach

F) Search Remote System for Files (OST) Recursive Search

I was assigned a task to audit systems that had OST files that were quite large, and I ended up finding them in more than one place but under a specific parent folder. I was able to create a PowerShell script that searches all items and only by file extension and create a report.
