Automating workflows

Since some years, i'm looking more for CLI options of the software i use, to a point where i learned to enjoy "command-line interfaces". This way i can create scripts and automate repetitive tasks. Even after two decades of typing characters into computers, it still feels like "breathing life" into all these things to me. Although i don't mind using or building a GUI, since i sit on both sides.
Creating rules and throwing "input" against it, to see how the program reacts, is a bit like playing with Lego "Technic" from my childhood. But the difference is that i can now make the parts myself, just by adding lines of code into a text editor. Connecting all these pieces, written by others or me, is a jigsaw puzzle without a real end, but certainly with the goal to get the job done.
Here i'm listing a few free apps i use regularly through a graphical user interface: 7Zip, AllDup, Audacity, "Everything" by David Carpenter, FileZilla, Notepad by Don Ho, TrayBackup, and WinMerge. Last but not least some icing on the cake: Dolphin Emulator with "Mario Kart Wii" via RomUlation. FYI, i got my first copy of Adobe Photoshop from an internship in June 2001.
