OPTIONS:
        --bytes-format 
            How to display the numbers of bytes [default: metric]  [possible values: plain, metric, binary]

        --column-width      
            Maximum widths of the tree column and width of the bar column

        --max-depth 
            Maximum depth to display the data (must be greater than 0) [default: 10]

        --min-ratio                     
            Minimal size proportion required to appear [default: 0.01]

        --quantity 
            Aspect of the files/directories to be measured [default: len]  [possible values: len, blksize, blocks]

        --total-width                 
            Width of the visualization


ARGS:
    ...    
            List of files and/or directories


EXAMPLES:
    Show disk usage chart of current working directory
    $ pdu

    Show disk usage chart of a single file or directory
    $ pdu path/to/file/or/directory

    Compare disk usages of multiple files and/or directories
    $ pdu file.txt dir/

    Show chart in block sizes instead of apparent sizes
    $ pdu --quantity=blksize

    Show data in plain numbers instead of metric units
    $ pdu --bytes-format=plain

    Show data in base 2¹⁰ units (binary) instead of base 10³ units (metric)
    $ pdu --bytes-format=binary

    Show disk usage chart of all entries regardless of size
    $ pdu --min-ratio=0

    Only show disk usage chart of entries whose size is at least 5% of total
    $ pdu --min-ratio=0.05

    Show disk usage data as JSON instead of chart
    $ pdu --min-ratio=0 --json-output | jq

    Visualize existing JSON representation of disk usage data
    $ pdu --min-ratio=0 < disk-usage.json
