Free rar files extract software for linux

Cabextract menu is just a little service menu that I put together for extracting MS .cab files.

It creates a directory with the same base name in the same directory as the .cab file and extracts to it. To use it, you have to have cabextract installed (and can be found here http://www.kyz.uklinux.net/cabextract.php.

CPAN::Mini::Extract is a Perl module that can create CPAN::Mini mirrors with the archives extracted.

SYNOPSIS

# Create a CPAN extractor
my $cpan = CPAN::Mini::Extract->new(
remote => http://mirrors.kernel.org/cpan/,
local => /home/adam/.minicpan,
trace => 1,
extract => /home/adam/.cpanextracted,
extract_filter => sub { /.pm$/ and ! /b(inc|t)b/ },
extract_check => 1,
);

# Run the minicpan process
my $changes = $cpan->run;

CPAN::Mini::Extract provides a base for implementing systems that download "all" of CPAN, extract the dists and then process the files within.
It provides the same syncronisation functionality as CPAN::Mini except that it also maintains a parallel directory tree that contains a directory located at an identical path to each archive file, with a controllable subset of the files in the archive extracted below.

How does it work

CPAN::Mini::Extract starts with a CPAN::Mini local mirror, which it will optionally update before each run. Once the CPAN::Mini directory is current, it will scan both directory trees, extracting any new archives and removing any extracted archives no longer in the minicpan mirror.

The layer extract plug-in is a Gimp plug-in that creates a new image/film by periodically extracting layers from another image.

It takes one interval (number of sequent layers) every period. The number of periods can be limited.

The Apache::FileManager module is a simple HTML file manager. It provides file manipulations such as cut, copy, paste, delete, rename, extract archive, create directory, create file, edit file, and upload files.
It also has the ability to rsync the server htdocs tree to another server with the click of a button.
Enhancements:
- prevented file edit screen from opening when cancel is clicked when creating new filenames
- fixed up documentation

Genetic Algorithm File Fitter (gaffitter) is a command-line software written in C++ that extracts --via Genetic Algorithm-- subsets of an input list of files/directories that best fit the given volume size (target), such as CD, DVD and others. Genetic Algorithm File Fitter is initially designed to run under Linux and POSIX systems, but easily portable to non-POSIX operating environment.
Using GA search, gaffitter improve different combinations of the files on the list so that the lost of space will be minimized. Ideal to be used for backups/records in CD, DVD and others.
Main features:
- Uses a global meta-heuristic (Genetic Algorithm search).
- The command-line interface provides high integration (via pipe) with other tools, i.e. works as a "filter".
- Pretty configurable. gaffitter have many input parameters to control/adjust its behavior (including GA params).
- It is free software! (GPL)
Usage:
gaffitter [options...] < files >
... | gaffitter - [options...] [files]
General options:
-t < n >, --target < n >
target size [default = 700]
--bytes

Enhancements:
- This release fixes a bug regarding an uninitialized variable and changes the default behavior of GAFFitter, which now extracts the volumes as much as possible (with unlimited iterations).

Hydranode Core is a modular, plugin-driven peer-to-peer client framework which is designed with true multi-network downloads in mind.
Hydranode Project can be used directly via the built-in shell functionality, or via external user interfaces.
To achieve the large number of features described in the previous section, HydraNode core needs to be extendible without causing feature bloat and increase in system requirements resulting from that. The only way to accomplish that is make the application completely modular - only a minimum set of features are provided by the core application; the rest of the features are implemented by optional loadable modules. Each file-sharing network should be in a separate module, as should be other additional features like e-mail notifications. With this design, the features are de-coupled from each other, thus greatly simplifying the debugging process, and allowing end user to select only the features he or she needs instead of what a programmer thought was best for him or her.
Second most important pre-requisite for a modern peer-to-peer application is platform-independence. The biggest differences in platforms are the graphical user interfaces, while the underlying structure of operating systems is rather similar. To achieve maximum portability, the core application should be decoupled from graphical user interfaces, which then could be written platform-dependently for each target platform; native user interfaces always perform better than interfaces designed for running on large number of platforms. To achieve this, the core application should not have any interactive graphical user interface of its own at all - it should only provide a protocol through which native graphical user interfaces and other application could communicate with it and control it. The protocol itself should be in human-readable format, but also be easily parse-able for client software; the reason for this would be to allow the possibility of interacting with the protocol directly through simple software like telnet, which would greatly simplify debugging process, but could also be useful even for end users as a crude remote control mechanism.
Related to the above comes the question of programming language to use for writing the core application. At this, C++ would be the most sensible choice, because it is widely used across all platforms and provides fastest code (which is required to achieve low system requirements); it allows (and even enforces) object-oriented design, and is easier to understand than C code. Additionally, since HydraNode strongly relies on module-writers, C++ coders are far easier to find than, say, Java coders.
As mentioned in previous section, quickest way to rapid development process is to give the users free access to the source code of the application; it increases possible developer/debugger-base significantly. Out of the myriad of open source licenses out there, GNU General Public License is most respected among users and developers, so HydraNode source code should follow the trend and be licensed under GNU GPL. Having the source code licensed under GNU GPL also allows us to use the almost infinite amount of existing code freely available through the internet, which could prove as a very useful option.
With the fore-seeable future of large number of co-developer base, it is necessary to clearly define the coding standards for the core application. Coding style is very personal; having large number of developers modifying the code will quickly lead to a mix of different styles and personalities, which in turn makes the code less readable, and thus less maintainable. There are several widely accepted coding standards floating around, and for this project we have chosen to use Linux Kernel coding standard; while originally written for C, the concepts still mostly hold for C++. Source code, however, is worth nothing without correct documentation which would give the future co-developers hints on what the original developers had in mind while writing/designing the application. Again, there several widely accepted documentation standards, out of which perhaps the most common is Doxygen-style. The reason behind this is that Doxygen is capable of extracting documentation from source files and generating web pages out of it, which can give a very quick and extensive overview of the entire application at a glance - something future developers will greatly appreciate.
The privacy of the user should be a serious concern for any modern peer-to-peer application developer; there are several institutions which tend to have a habit of spying upon the users and invading their privacy. The simplest solution would be to block the IP addresses of those groups; even better solution would be to simply stay off their radar. The first part can be implemented within the core application since it controls the low-level networking functionality; second part can be implemented by networking plugins depending on the specific networks.
Since the core application will eventually have a large number of very different networking plugins, we have the problem of bandwidth management. The end user shouldnt be bothered with each specific plugins bandwidth limiting settings, so the bandwidth limits should be managed by the main application, which in turn could either allow or deny requests for bandwidth to modules. This setting should be fully configurable, allowing end user to either have the bandwidth shared equally among the plugins, or in favor of one or several specific plugins.
Various file-sharing networks use very different files identifying methods - most often this is a checksum of the file, sometimes accompanied by file size; additionally, there is files meta-data, which can help the end-user identify the file. Since this feature is common to all file-sharing networks, while only differing in the actual checksum used, it should also be handled by the core application. Several points must be considered here - the core application should be able to generate a large number of checksums and store them. It should also be capable of extracting meta-data of files, as well as do cross-references with checksums - given a checksum from one network, it should be able to find the same file on second network (provided the file is known). However, no single client can know the checksums of all files of all networks, which means that the cross-referencing functionality will be of little use locally - this needs a central database which could store the checksums of all files from all networks, and provide cross-referencing functionality. Heres where Myradin comes in - it does exactly that. While support for Myradin shouldnt be completely integrated since it isnt really a part of the application, it could be an optional plugin that retrieves and submits checksums to the central database.
The last feature is far more important than is obvious on first impression; this is the feature that will eventually allow real multi-network simultaneous downloads of same file. The problem is - since each network uses different checksums for files, it is impossible to identify the same file on two separate networks - you dont know the file is the same until you have downloaded the entire file and generated a checksum out of it. However, with a central database which stores checksums of different files from multiple networks, it would be possible to retrieve the checksums of a file on all other networks provided you have the checksum of a file from one network, thus allowing downloading the same file from two or more networks simultaneously. Upon completition, files actual checksum could again be tested against all known checksums to provide even higher corruption protection than single-network downloads. The central database would also contain files meta-data, which would allow end-users to more clearly identify fake files, thus improving the overall quality of files on all file-sharing networks.

File::Comments is a Perl module that ecognizes file formats and extracts format-specific comments.

SYNOPSIS

use File::Comments;

my $snoop = File::Comments->new();

# *----------------
# | program.c:
# | /* comment */
# | main () {}
# *----------------
my $comments = $snoop->comments("program.c");
# => [" comment "]

# *----------------
# | script.pl:
# | # comment
# | print "howdy!n"; # another comment
# *----------------
my $comments = $snoop->comments("script.pl");
# => [" comment", " another comment"]

# or strip comments from a file:
my $stripped = $snoop->stripped("script.pl");
# => "print "howdy!n";"

# or just guess a files type:
my $type = $snoop->guess_type("program.c");
# => "c"

File::Comments guesses the type of a given file, determines the format used for comments, extracts all comments, and returns them as a reference to an array of chunks. Alternatively, it strips all comments from a file.

Currently supported are Perl scripts, C/C++ programs, Java, makefiles, JavaScript, Python and PHP.

The plugin architecture used by File::Comments makes it easy to add new formats. To support a new format, a new plugin module has to be installed. No modifications to the File::Comments codebase are necessary, new plugins will be picked up automatically.

File::Comments can also be used to simply guess a files type. It it somewhat more flexible than File::MMagic and File::Type. File types in File::Comments are typically based on file name suffixes (*.c, *.pl, etc.). If no suffix is available, or a given suffix is ambiguous (e.g. if several plugins have registered a handler for the same suffix), then the files content is used to narrow down the possibilities and arrive at a decision.

WARNING: THIS MODULE IS UNDER DEVELOPMENT, QUALITY IS ALPHA. IF YOU FIND BUGS, OR WANT TO CONTRIBUTE PLUGINS, PLEASE SEND THEM MY WAY.
