NAME App::DuplicateFilesUtils - CLI utilities related to duplicate files VERSION This document describes version 0.005 of App::DuplicateFilesUtils (from Perl distribution App-DuplicateFilesUtils), released on 2022-08-19. 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_code, $reason, $payload, \%result_meta] Move duplicate files (except one copy) to a directory. This utility will find all duplicate sets of files and move all of the duplicates (except one) for each set to a directory of your choosing. See also: show-duplicate-files which lets you manually select which copies of the duplicate sets you want to move/delete. This function is not exported. This function supports dry-run operation. Arguments ('*' denotes required arguments): * dir* => *dirname* Directory to move duplicate files into. Special arguments: * -dry_run => *bool* Pass -dry_run=>1 to enable simulation mode. Returns an enveloped result (an array). First element ($status_code) is an integer containing HTTP-like status code (200 means OK, 4xx caller error, 5xx function error). Second element ($reason) is a string containing error message, or something like "OK" if status is 200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata. Return value: (any) show_duplicate_files Usage: show_duplicate_files() -> [$status_code, $reason, $payload, \%result_meta] Show duplicate files. This is actually a shortcut for: % uniq-files -a --show-count --show-size --group-by-digest -R .

But there's also move-duplicate-files-to to automatically move all the duplicates (but one, for each set) to a directory of your choice. To perform other actions on the duplicate copies, for example delete them, you can use uniq-files directly e.g. (in bash): % uniq-files -R -D * | while read f; do rm "$p"; done This function is not exported. No arguments. Returns an enveloped result (an array). First element ($status_code) is an integer containing HTTP-like status code (200 means OK, 4xx caller error, 5xx function error).

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via: % prove -l If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me. COPYRIGHT AND LICENSE This software is copyright (c) 2022, 2020 by perlancar <perlancar@cpan.org>.

BUGS Please report any bugs or feature requests on the bugtracker website <https://rt.cpan.org/Public/Dist/Display.html?Name=App-DuplicateFilesUti ls> When submitting a bug or request, please include a test-file or a patch to an existing test-file that illustrates the bug or desired feature.
