Diskonaut – A Terminal Disk Space Navigator for Linux

diskonaut is a simple terminal disk space navigator built using Rust and supports Linux and macOS. To use it, specify an absolute path in your file system, for example, /home/tecmint or run it in the directory of interest, it will scan the directory and maps it to memory enabling you to explore its contents. It allows you to inspect space usage even during the scanning process.

When the scanning is complete, you can navigate through subdirectories, getting a visual treemap representation of what’s consuming your disk space. diskonaut allows you to delete files and directories and as a result, tracks the amount of space you have freed up in the process. It also supports keyboard shortcuts to ease navigation.

    Other than the more “graphic” display of disk usage, is it any better than ncdu?

    I’d prefer ncdu because it is in the Repos of all distros I’ve used so far (Debian based).
