Ever seen a file ending in `.sh` and wondered what it was? You've stumbled upon a shell script, a powerful tool for automating tasks and controlling your operating system (primarily Linux and macOS). Think of it as a mini-program written in a language your computer understands.
These `.sh` files contain a series of commands that are executed sequentially by the shell (like Bash or Zsh). From simple tasks like renaming multiple files at once, to complex system administration duties, `.sh` files can handle it.
So, how do you use them? First, ensure the file has execute permissions (using `chmod +x your_script.sh`). Then, you can run it from your terminal using `./your_script.sh`.
Understanding `.sh` files opens a whole new world of efficiency and customization. Start exploring and automate your digital life!
