lsd is a directory listing tool and directory tree visualizer designed as a modern replacement for the standard Unix ls command. It provides a command line interface for listing directory contents and visualizing hierarchical folder structures with enhanced visual formatting.
The utility distinguishes itself through customizable themes, allowing users to modify the output appearance by mapping specific colors and icons to file names, types, or extensions. It uses extension-based icon mapping to provide visual file type identification via specific glyphs.
The tool covers functional domains including terminal interface customization and filesystem navigation. It retrieves metadata such as file sizes, permissions, and modification dates to render directory listings as either flat lists or recursive trees.
