duviz is a (Python 3) command-line tool to visualize disk space usage.
It’s like the plethora of desktop applications and widgets (e.g. Filelight, DaisyDisk, WinDirStat, JDiskReport, TreeSize, SpaceSniffer, …), but instead of a fancy GUI with animated pie charts and shaded boxes you get a funky “ASCII art style hierarchical tree of bars” in your shell.
This is free and open source software.
Key Features
- Basically it consists of just one Python 3 script duviz.py. No installation required: put it where you want it. Use it how you want it.
- Only uses standard library and just depends on du and ls utilities, which are available out of the box on a typical Unix platform (Linux, macOS)
- Speed. No need to wait for a GUI tool to get up and running, let alone scanning your disk. The hard work is done by du (or ls), which run an C-speed.
- Progress reporting while you wait. Be hypnotized!
- Detects your terminal width for maximum visualization pleasure.
- Not only supports “disk usage” based on file size, but also allows to count files (inode count mode) or give a size breakdown of ZIP or tar files.
- Option to use terminal colors for the boxes instead of ASCII art.
