Preliminaries: Linux File Structure and Commands
Learn the fundamentals of Linux file organization and commands to effectively manage file paths and run Ruby code. This lesson helps you navigate directories, list files, and view content using Linux CLI tools, preparing you for file handling tasks in Ruby.
