NAME
    App::DuplicateFilesUtils - CLI utilities related to duplicate files

VERSION
    This document describes version 0.002 of App::DuplicateFilesUtils (from
    Perl distribution App-DuplicateFilesUtils), released on 2020-05-28.

DESCRIPTION
    This distributions provides the following command-line utilities:

    *   move-duplicate-files-to

    *   show-duplicate-files

FUNCTIONS
  move_duplicate_files_to
    Usage:

     move_duplicate_files_to(%args) -> [status, msg, payload, meta]

    Move duplicate files (except one copy) to a directory.

    Moving is currently done using Perl's "rename()", so files cannot be
    moved across filesystems.

    See also: show-duplicate-files which lets you manually select which
    copies of the duplicate sets you want to move/delete.

    This function is not exported.

    This function supports dry-run operation.

    Arguments ('*' denotes required arguments):

    *   dir* => *dirname*

        Directory to move duplicate files into.

    Special arguments:

    *   -dry_run => *bool*

        Pass -dry_run=>1 to enable simulation mode.

    Returns an enveloped result (an array).

    First element (status) is an integer containing HTTP status code (200
    means OK, 4xx caller error, 5xx function error). Second element (msg) is
    a string containing error message, or 'OK' if status is 200. Third
    element (payload) is optional, the actual result. Fourth element (meta)
    is called result metadata and is optional, a hash that contains extra
    information.

    Return value: (any)

  show_duplicate_files
    Usage:

     show_duplicate_files() -> [status, msg, payload, meta]

    Show duplicate files.

    This is actually a shortcut for:

     % uniq-files -a --count --show-size --group-by-digest -R .

    Sample output:

     % show-duplicate-files
