Last Updated on 2024-10-12 by Clay

ncdu is a disk usage analyzer tool based on NCurses, mainly used to view and manage disk space. It provides a terminal interface to browse the directory structure, allowing users to quickly explore directories and see the size of each file or folder. This helps users identify directories or files that are taking up a large amount of space.
