Ncdu
Ncdu (NCurses Disk Usage) is a command-line disk usage analyzer tool for Unix-like systems that provides an interactive, text-based interface using ncurses. It scans directories to display disk usage in a hierarchical format, allowing users to navigate, sort, and manage files and folders efficiently. It is particularly useful for identifying large files or directories that are consuming excessive disk space.
Developers should use Ncdu when they need to quickly analyze and free up disk space on servers, development machines, or embedded systems, especially in headless environments without a graphical interface. It is ideal for troubleshooting storage issues, cleaning up temporary files, or optimizing deployments by pinpointing space hogs in directories like logs, caches, or build artifacts.
