It is a lightweight, terminal-based disk space analyzer written in C that uses the ncurses library to render a fast, interactive text interface directly in the terminal window. You run it on a directory, it scans the entire tree in seconds, and then presents an immediately sortable, navigable view of what is consuming your storage, from the largest directories at the top all the way down to individual files.\n<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\n  The traditional du command on Linux dumps a flat list of directory sizes to standard output, which becomes unwieldy the moment you have more than a handful of directories to review. It offers no interactivity, no real-time sorting, and no way to drill down into a subdirectory without writing another command. ncdu replaces that entire workflow with a single command that stays open, allows you to navigate directories with arrow keys, and lets you delete files directly from the interface.\n<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><a id=\"post-17555-_ko7r8lz7fchc\"><\/a>Prerequisites before installing ncdu on Ubuntu 26.04<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">\n  ncdu has minimal requirements.
