Free extract data from pdf software for linux

libextractor is a library that is used to extract meta-data from files of arbitrary type. It is designed to use helper-libraries to perform the actual extraction, and to be trivially extendable by linking against external extractors for additional file types. libextractor is part of the GNU project. Our official GNU website can be found at http://www.gnu.org/software/libextractor/. libextractor can be downloaded from this site or the GNU mirrors.
The goal is to provide developers of file-sharing networks or WWW-indexing bots with a universal library to obtain simple keywords to match against queries. libextractor contains a shell-command "extract" that, similar to the well-known "file" command, can extract meta-data from a file an print the results to stdout.
Currently, libextractor supports the following formats: HTML, PDF, PS, OLE2 (DOC, XLS, PPT), OpenOffice (sxw), StarOffice (sdw), DVI, MAN, MP3 (ID3v1 and ID3v2), OGG, WAV, JPEG, GIF, PNG, TIFF, DEB, RPM, TAR(.GZ), ZIP, ELF, REAL, RIFF (AVI), MPEG, QT and ASF.
Also, various additional MIME types are detected.
libextractor is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.
Enhancements:
- This release fixes various build problems and a crash with recent versions of libgsf.
vAn incomplete manual was added.

MDF audio extracter project is a tool to extract audio data from MDF/MDS audio cd images to wav or raw files. Tracks will be extracted to the current directory and named track_[num].wav or track_[num].raw. Output can also be redirected to stdout to allow the audio data to be fed to an encoder or player directly.
You need both a .mds and .mdf file to be able to extract tracks. The .mds file contains the information about the tracks, while the .mdf file contains the actual data. They usually should have the same name (except for the extension ofcourse). This is case sensitive, so for example FileName is not the same as filename.
Usage: mdfextract [options] file.mds
Options:
-i output mds info instead of extracting
-r extract raw track data
-s output to stdout instead of file
-t < num > extract single track (num > 0)
-q quiet, no output
Version restrictions:
- Probably does not work on big endian archs.

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.

THC-ManipulateData can search data on a harddisk/partition/file, extract the part you are interested in, and write it back after you modified it.
Useful to find and modify really all unencrypted Logfiles on a system. Does everything in RAW mode, and hence does not tamper a/m/ctimes.
It comes with 4 tools:
Syntax of search_data: ./search_data [-i] [-d] blockdevice searchstring
-i - the only parameter which is optional. This does the
search case insensitive.
-d - dump the found occasions in hex
blockdevice - a blockdevice you want to search for data. It need
not to be a blockdevice, it can be anything, but normaly
you use it on these.
searchstring - a string you want to search for
The blockdevice is searched for the occurance of searchstring, which are printed with location when found.
Example: ./search_data -i /dev/hda3 "connect from 10.0.0.1"
Output looks like:
found at 234600: connect from 10.0.0.1/unresolved (UNKNOWN)
Syntax of read_data: ./read_data blockdevice start_address no_of_bytes
blockdevice - a blockdevice you want to get your data from. It need not to be a blockdevice, it can be anything, but normaly you use it on these.
start_address - from which offset of the blockdevice you want to extract data from
no_of_bytes - how many bytes of data starting at the start_address you want to extract in a file.
The output filename is always START_ADDRESS.NO_OF_BYTES
Example: ./read_data /dev/hda3 234653 1024
writes 1024 bytes of data from /dev/hda3 starting from offset 234653 to the file "234653.1024"
Syntax of write_data: ./write_data blockdevice filename
blockdevice - a blockdevice you want to write your data to. It need not to be a blockdevice, it can be anything, but normaly you use it on these.
filename - the data you want to write to the blockdevice. For error protection, the location where it is put it gathered from the filename - as you can see above from read_data. If you modified the data extracted with read_data into the file, it may not have a different size than defined in the filename! The data in filename is written to the blockdevice
Example: ./write_data /dev/hda3 234653.1024
writes 1024 bytes of data to /dev/hda3 starting at offset 234653 with the
data read from the file "234653.1024"
Syntax of replace_data: ./replace_data [-i] blockdevice searchstring replacestring
-i - the only parameter which is optional. This does the search case insensitive.
blockdevice - a blockdevice you want to search for data. It need not to be a blockdevice, it can be anything, but normaly you use it on these.
searchstring - a string you want to search for
replacestring - the string you want to replace the found entries with
The blockdevice is searched for the occurance of searchstring, and is then replaced.
Example: ./replace_data -i /dev/hda3 "connect from 1.0.0.1" "Remap table failure "
Output looks like:
found at 234600 - replaced
Enhancements:
- fixed a bug in read/write_data, seeks over 2gb now succeed
- added -d for hexdump display of occasions found in search_data

Aqua Data Studio program is a database query tool and administration tool that allows developers to easily create, edit, and execute SQL scripts, as well as browse and visually modify database structures.
Aqua Data Studio provides an integrated database environment with a single consistent interface to all major relational databases. This allows the database administrator or developer to tackle multiple tasks simultaneously from one application.
Main features:
Query Analyzer/Window
- Aqua Data Studios sophisticated Query Analyzer allows users to work on database scripts with specific RDBMS syntax highlighting and auto-completion to develop and test SQL scripts. Other features to speed up development include SQL automation, auto-describe and sortable multi-grid results. The query analyzer also provides client side variable binding, allowing a user to execute stored procedures or functions with local variables binded to receive out parameters. The query window also provides two modes of operation, using a SplitPane View or a MultiTab View for the editor and the query results.
Schema Browser & Visual Editing
- Its graphical browsing capabilities allow you to understand the structure and dependencies of the database schema with a single mouse click. The schema browser also allows you to visually edit any schema object with a graphical design form to CREATE, ALTER or DROP the object. Visual editing supports Tables, Indexes, Procedures, Data Types and other schema objects. The visual editors also provides an SQL preview of all the commands to be executed to commit the operation.
Schema Extraction & DDL Scripting
- Its graphical browsing allows you to extract the structure definition of all schema objects and to script the SQL DDL and DML (eg CREATE, ALTER, DROP, SELECT, INSERT, UPDATE and DELETE) syntax for database schema objects (including Tables, Views, Triggers, Stored Procedures and Functions).
Table Data Editor
- A powerful Table Data Editor allows you to modify your results graphically and save them. By writing a single table SELECT statement in the Query Analyzer and clicking on the Execute Edit button, a separate window is opened with the query results for you to edit and save. You may also browser to a table in the schema browser and select the Edit Table from the popup menu to edit the first 1000 records in a table.
Enhancements:
- Enhancements in this release include OS X Integration, Windows integration, complete and customizable keymapping, a schema difference tool, a directory difference tool, a file difference tool, a tab difference tool, a copy history difference tool, SQL Server DBA tools, and Sybase DBA tools.
- In total, there were over 100 new features.

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.

PandaLex is the PDF parsing code from Panda, which has been split into its own project to increase its utility.

It is a flex and bison description of the PDF specification, which allows programmers to define callbacks to handle different document elements.
