diskonaut
A terminal-based disk space navigator that visualizes storage usage with interactive treemaps.
What is diskonaut?
diskonaut is a terminal-based disk space navigator that scans directories and displays storage usage through interactive visual treemaps. It helps users identify what files and folders are consuming disk space and allows them to delete items while tracking freed space. The tool provides real-time exploration even during scanning operations.
System administrators, developers, and power users who work in terminal environments and need to analyze and manage disk space efficiently.
Unlike traditional command-line disk analyzers, diskonaut offers visual treemap representations that make it easier to understand storage distribution at a glance. Its interactive navigation and real-time scanning provide immediate insights without waiting for complete scans to finish.
Overview
Terminal disk space navigator 🔭
Use Cases
Best For
- Identifying large files and folders consuming disk space
- Visualizing storage distribution through treemaps in terminal
- Interactive disk cleanup sessions with deletion tracking
- Quick disk usage analysis without leaving the command line
- Managing storage on remote servers via SSH
- Comparing folder sizes within complex directory structures
Not Ideal For
- Environments where GUI-based disk analyzers are preferred for visual clarity on large screens
- Automated scripts requiring headless disk usage analysis without interactive prompts
- Systems with limited RAM, as diskonaut indexes directory metadata to memory during scanning
- Projects needing exportable reports or historical data for audit purposes
Pros & Cons
Pros
Allows exploration of directories even while scanning continues, enabling immediate insights without waiting for full completion, as mentioned in the README's live scanning feature.
Uses nested rectangles to graphically display disk usage, making it easy to identify large files and folders at a glance, which is core to its value proposition.
Tracks freed space after deletions within the session, providing real-time feedback on cleanup efforts, as highlighted in the key features.
Supported on Linux, macOS, and Windows with multiple installation options including package managers and prebuilt binaries, ensuring wide accessibility.
Cons
Indexes all directory metadata to memory during scanning, which can lead to high RAM usage and performance issues on large or deep filesystems, a trade-off admitted in the README.
Primarily designed for interactive use, lacking built-in features for scripting or batch processing, making it unsuitable for automated disk analysis workflows.
Does not mention support for filtering by file type, date, or other attributes, which limits targeted cleanup and detailed analysis compared to more feature-rich tools.
