NAME

list-common-files - List files that are found in {all,more than one} directories

VERSION

This document describes version 0.002 of list-common-files (from Perl distribution App-FileCommonUtils), released on 2021-05-25.

SYNOPSIS

Usage:

% list-common-files [--detail] [--dir=s+] [--dirs-json=s] [--format=name]
    [--json] [--min-occurrence=s] [--(no)naked-res] [--no-detail]
    [--nodetail] [--page-result[=program]] [--view-result[=program]] <dir>
    ...

DESCRIPTION

This routine lists files that are found in all specified directories (or, when min_occurrences option is specified, files that are found in at least a certain number of occurrences. Note that only filenames are compared, not content/checksum. Directories are excluded.

OPTIONS

* marks required options.

Main options

--detail

Whether to return detailed result per file.

If set to true, instead of an array of filenames:

["file1", "file2"]

it will instead return a hash with filename as key and another hash containing detailed information:

{
    "file1" => {
        dirs => ["dir1", "dir2"], # in which dirs the file is found
    },
    "file2" => {
        ...
    },
}

--dir=s@*

Can also be specified as the 1st command-line argument and onwards.

Can be specified multiple times.

--dirs-json=s

See --dir.

Can also be specified as the 1st command-line argument and onwards.

--min-occurrence=s

Output options

--format=s

Choose output format, e.g. json, text.

Default value:

undef

--json

Set output format to json.

--naked-res

When outputing as JSON, strip result envelope.

Default value:

0

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]

--page-result

Filter output through a pager.

--view-result

View output using a viewer.

Other options

--help, -h, -?

Display help message and exit.

--version, -v

Display program's version and exit.

COMPLETION

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

bash

To activate bash completion for this script, put:

complete -C list-common-files list-common-files

in your bash startup (e.g. ~/.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 modules using cpanm-shcompgen which can activate shell completion for scripts immediately.

tcsh

To activate tcsh completion for this script, put:

complete list-common-files 'p/*/`list-common-files`/'

in your tcsh startup (e.g. ~/.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 shcompgen (see above).

other shells

For fish and zsh, install shcompgen as described above.
