=head1 NAME

uniq-files - Report or omit duplicate file contents

=head1 VERSION

This document describes version 0.10 of uniq-files (from Perl distribution App-UniqFiles), released on 2015-08-17.

=head1 SYNOPSIS

Usage:

 % uniq-files [options] <files>...

Examples:

{en_US List all files which do no have duplicate contents}:

 % uniq-files *

{en_US List all files which have duplicate contents}:

 % uniq-files -d *

{en_US List number of occurences of contents for each file}:

 % uniq-files -c *

=head1 DESCRIPTION

Given a list of filenames, will check each file size and content for duplicate
content. Interface is a bit like the C<uniq> Unix command-line program.

=head1 OPTIONS

C<*> marks required options.

=head2 Configuration options

=over

=item B<--config-path>=I<filename>

{en_US Set path to configuration file}.

Can be specified multiple times.

=item B<--config-profile>=I<s>

{en_US Set configuration profile to use}.

=item B<--no-config>

{en_US Do not use any configuration file}.

=back

=head2 Environment options

=over

=item B<--no-env>

{en_US Do not read environment for default options}.

=back

=head2 Output options

=over

=item B<--format>=I<s>

{en_US Choose output format, e.g. json, text}.

Default value:

 undef

=item B<--json>

{en_US Set output format to json}.

=item B<--naked-res>

{en_US When outputing as JSON, strip result envelope}.

Default value:

 0

{en_US 
By default, when outputing as JSON, the full enveloped result is returned, e.g.:

    [200,"OK",[1,2,3],{"func.extra"=>4}]

The reason is so you can get the status (1st element), status message (2nd
element) as well as result metadata/extra result (4th element) instead of just
the result (3rd element). However, sometimes you want just the result, e.g. when
you want to pipe the result for more post-processing. In this case you can use
`--naked-res` so you just get:

    [1,2,3]
}


=back

=head2 Other options

=over

=item B<--count>

{en_US Whether to return each file content's number of occurence}.

{en_US 
1 means the file content is only encountered once (unique), 2 means there is one
duplicate, and so on.
}


=item B<--files-json>=I<s>

See C<--files>.

=item B<--files>=I<s@>*

Can be specified multiple times.

=item B<--help>, B<-h>, B<-?>

{en_US Display help message and exit}.

=item B<--no-check-content>

{en_US 
If set to 0, uniqueness will be determined solely from file size. This can be
quicker but might generate a false positive when two files of the same size are
deemed as duplicate even though their content are different.
}


=item B<--no-report-unique>

=item B<--report-duplicate>=I<i>

{en_US Whether to return duplicate items}.

Default value:

 2

{en_US 
Can be set to either 0, 1, 2.

If set to 2 (the default), will only return the first of duplicate items. For
example: file1 contains text 'a', file2 'b', file3 'a'. Only file1 will be
returned because file2 is unique and file3 contains 'a' (already represented by
file1).

If set to 1, will return all the the duplicate items. From the above example:
file1 and file3 will be returned.

If set to 0, duplicate items will not be returned.
}


=item B<--version>, B<-v>

{en_US Display program's version and exit}.

=item B<-d>

{en_US Alias for --noreport-unique --report-duplicate=1}.

See C<--no-report-unique>.

=item B<-u>

{en_US Alias for --report-unique --report-duplicate=0}.

See C<--no-report-unique>.

=head1 COMPLETION

This script has shell tab completion capability with support for several
shells.

=head2 bash

To activate bash completion for this script, put:

 complete -C uniq-files uniq-files

in your bash startup (e.g. C<~/.bashrc>). Your next shell session will then
recognize tab completion for the command. Or, you can also directly execute the
line above in your shell to activate immediately.

It is recommended, however, that you install L<shcompgen> which allows you to
activate completion scripts for several kinds of scripts on multiple shells.
Some CPAN distributions (those that are built with
L<Dist::Zilla::Plugin::GenShellCompletion>) will even automatically enable shell
completion for their included scripts (using C<shcompgen>) at installation time,
so you can immadiately have tab completion.

=head2 tcsh

To activate tcsh completion for this script, put:

 complete uniq-files 'p/*/`uniq-files`/'

in your tcsh startup (e.g. C<~/.tcshrc>). Your next shell session will then
recognize tab completion for the command. Or, you can also directly execute the
line above in your shell to activate immediately.

It is also recommended to install C<shcompgen> (see above).

=head2 other shells

For fish and zsh, install C<shcompgen> as described above.

=head1 ENVIRONMENT

=head2 UNIQ_FILES_OPT => str

Specify additional command-line options

=head1 CONFIGURATION FILE

This script can read configuration file, which by default is searched at C<~/.config/uniq-files.conf>, C<~/uniq-files.conf> or C</etc/uniq-files.conf> (can be changed by specifying C<--config-path>). All found files will be read and merged.

To disable searching for configuration files, pass C<--no-config>.

Configuration file is in the format of L<IOD>, which is basically INI with some extra features. 

You can put multiple profiles in a single file by using section names like C<[profile=SOMENAME]>. Those sections will only be read if you specify the matching C<--config-profile SOMENAME>.

List of available configuration parameters:

 check_content (see --no-check-content)
 count (see --count)
 files (see --files)
 format (see --format)
 naked_res (see --naked-res)
 report_duplicate (see --report-duplicate)
 report_unique (see --no-report-unique)

=head1 FILES

~/.config/uniq-files.conf

~/uniq-files.conf
