I needed to send my accountant my paystubs, so I went to ADP to get them. ADP only lets you download 10 files at once, leading to many subfolders. I wanted to move all the PDFs from these subfolders to the main folder. This made me think of comparing Bash and PowerShell by solving this task. This started my "Bash vs. PowerShell" series. I aim to keep these lessons brief, focusing on real-world issues. They're great for regular users and those interested in scripting.
