Script files are text files that contain a series of commands or instructions written in a programming or scripting language. These files are used to automate tasks, run programs, or perform specific functions on a computer. Common scripting languages include Python, JavaScript, and Bash. When executed, the commands in a script file are processed sequentially, allowing users to streamline repetitive tasks. Script files can be created and edited using any text editor, making them accessible for both beginners and experienced programmers. They are often saved with specific file extensions, such as .py for Python scripts or .sh for Bash scripts. This helps the operating system recognize and execute the file correctly.
