tdu (Top Disk Usage) is a command-line utility for identifying the files and directories consuming the most disk space. It examines a specified directory tree and produces a summary highlighting the largest storage consumers.
The application is designed for users who want a compact report rather than an interactive disk browser. Its output focuses on the biggest files and directories, making it easier to identify where further investigation may be worthwhile.
tdu uses an approach comparable to the du -skx command and provides options for controlling the amount of information displayed. Users can adjust the number of large files listed, inspect top-level directories and request information about unusually deep paths.
The utility also reports several types of filesystem entries and scanning problems. Results can be exported using Ncdu’s JSON format, allowing the collected information to be examined with compatible tools.
This is free and open source software.
