Personally, I would use the terminal, too for a throwaway use case like this. But GUIs are very good at that and faster when you do more than the naïve case, they also allow to see intermediate steps. For your use case, on macOS open Automator.app and add three actions 1. "ask for finder items" (the source folder) 2. "filter finder items" (by name) 3. "copy finder items" (to target folder) This takes roughly 5 clicks, 10 seconds at most. Repeatability and configurability is where the GUI action shines. With only one click more you can - add filtering by size, opening date, modification date, etc. in addition or a combination thereof - do the same action for multiple source folders and the same target folder - choose whether you want to replace existing files - add it as a folder action that runs automatically on modification of the source folder Arguably much slower on the terminal. Alternative on macOS, that works on all other major OS with similar shortcuts and a similar feature set, just not repeatable: 1. Go to source folder (shift-cmd-G) 2. Filter (cmd-shift-F) 3. Copy (cmd-A, cmd-C) 4. Go to target folder (shift-cmd-G) 5. Paste (cmd-V) This repeatability, configurability and automation is where GPT falls short, for now.
