## Historique du projet et usages

btdu is a sampling disk-usage profiler for btrfs. It exists because copy-on-write snapshots, reflinks, extent sharing, and compression make classic directory walkers like du and ncdu poor explanations of real btrfs space usage.

### Historique du projet

CyberShadow started btdu in November 2020, with the first public release tag v0.1.0 shortly afterward. The project is written for the btrfs filesystem and uses sampling over filesystem space rather than a conventional recursive directory traversal.

The README explains that btdu samples random points in the disk space, asks btrfs what is stored there, records a representative path, and repeats indefinitely. The result is initially approximate but becomes progressively more accurate as sampling continues.

### Historique d'adoption

btdu has a narrower audience than general disk analyzers, but the README documents several distribution paths: native distro packages where available, static binaries from GitHub releases, latest CI builds, Nix flakes, and source builds using the D compiler and Dub.

The Homebrew and Nix packaging in the input reflects that btrfs users often still want btdu available from cross-platform package managers even though its runtime target is btrfs rather than generic macOS storage.

### Modes d'utilisation

Users run btdu with root privileges against the top-level subvolume of a btrfs filesystem. It can launch an interactive terminal UI, run headless for scripts, export and import sampling results, compare baselines, and use expert or physical-space modes for deeper analysis.

### Pourquoi les passionnés de paquets s'y intéressent

btdu is significant because it packages filesystem theory into a small terminal tool. It is not another ncdu clone; it is a btrfs-specific answer to shared extents, compression, snapshots, unreachable extent fragments, and logical-versus-physical allocation.

### Chronologie

- 2020: First git commit and v0.1.0 release.
- 2025: v0.6.0 release appears in git history.
- 2026: v0.7.2 release appears in git history.

### Related projects

- The README contrasts btdu with ncdu for classic disk-usage analysis.
- The README links compsize as a special-purpose btrfs compression-space tool.
- The README names btsdu, the Btrfs Snapshot Disk Usage Analyzer, in its See Also section.
