NAME
btdu - sampling disk usage profiler for btrfs

SYNOPSIS
btdu [OPTION]... PATH

DESCRIPTION
btdu is a sampling disk usage profiler for btrfs. For a detailed description, please see the full documentation: https://github.com/CyberShadow/btdu#readme

OPTIONS

PATH
    Path to the root of the filesystem to analyze

-j, --procs=N
    Number of sampling subprocesses
     (default is number of logical CPUs for this system)

--seed=N
    Random seed used to choose samples

-p, --physical
    Measure physical space (instead of logical).

-x, --expert
    Expert mode: collect and show additional metrics. Uses more memory.

-i, --interval=DURATION
    Set UI refresh interval. Specify 0 to refresh as fast as possible.

--headless
    Run without launching the result browser UI.

-n, --max-samples=N
    Stop after collecting N samples.

--max-time=DURATION
    Stop after running for this duration.

--min-resolution=SIZE
    Stop after achieving this resolution (e.g. "1MB" or "1%").

-o, --export=PATH
    On exit, export the collected results to the given file.

-F, --export-format=FORMAT
    Export format (guessed from extension if not specified).

--export-seen-as
    When exporting, include 'seenAs' data showing shared paths.

--prefer=PATTERN
    Prioritize allocating representative samples in the given path.

--ignore=PATTERN
    Deprioritize allocating representative samples in the given path.

--du
    On exit, export represented size estimates in 'du' format to standard output.

-f, --import
    Instead of analyzing a btrfs filesystem, read previously collected results saved with --export from PATH.

-c, --compare=PATH
    Compare against a baseline from a previously exported file.
