Free archive software for linux

ln_local is a simple shell script for managing the installation of software packages (typically in /usr/local). Its a program between stow and lndir/cleanlinks.

The approach used by ln_local (based on Stow) is to install each package into its own tree, then use symbolic links to make it appear as though the files are installed in the common tree (see examples for more details).

Contrary to stow, ln_local create all subdirectory tree and then create all symbolic links (stow create simbolic links for subdirectories and normals files, so conflicts may appends when two programs share the same subdirectory).

Usage

Usage: ln_local [options] [do] Action

Action : create | delete | clean
create : create symlink and directory in /usr/local from current directory
delete : delete symlink and empty directory in /usr/local from current directory
clean : remove broken symlink and empty directory in /usr/local

If do is presents in the command line then changes are made,
else NO CHANGE ARE MADE

Options are :
-s, --source the source directory (default:current directory)
-t, --target the target directory (/usr/local)
-V, --version display version and exit
-u, --usage long help
-h, --help display this help

Example

Standard way to use ln_local:

* download source package (.tar.gz, tar.bz2 ...)

* extract the archive:
tar -xzvf archive-x.x.x.tar.gz
or tar -xjvf archive-x.x.x.tar.bz2

* go to archive directory:
cd archive-x.x.x

* configure the program compilation:
./configure --prefix="/usr/install/archive-x.x.x"

* build the program:
make

* install the program:
make install
or make install DESTDIR=/usr/install/archive-x.x.x if theres no ./configure in this last case, you may have to edit manually the Makefile.

* create symlinks in /usr/local:
cd /usr/install/archive-x.x.x
ln_local create do

* delete the source and archive
cd in the archive-x.x.x.tar.gz directory
rm -rf archive-x.x.x*

you can change the target directory (/usr/local) by editing the file /usr/local/bin/ln_local or use the --target option

To remove an existing program:
cd /usr/install/archive-x.x.x
ln_local delete do

To clean the /usr/local directory:
ln_local clean do

To remove definitively a program:
rm -rf /usr/install/archive-x.x.x
ln_local clean do

If you want to see what ln_local will do, remove the do in create, delete and clean action, so no action will be done

javaSVNUpdater is a Java library that allows an application to update or patch itself automatically.

The versioning information about the application needs to be stored in a subversion archive, and committing to the archive effects the distribution of new versions.

It includes an updater wizard and an executor to spawn a separate process for proceeding with updates.

Confstore is a configuration backup utility. Confstore scans your system for all recognised configuration files and then stores them in a archive. Confstore can also restore configuration from a previously created archive.

Synonym that allows a company to easily archive all email messages going in and out. It can copy mail messages, delete, reject or add a text and/or html signature based on a XML based configuration file listing regular expression rules.

An archive containing all the messages that passed through a companys MTA ensures no messages are lost.

Even when using public folders with read-only access, some messages might not contain the public folder address in the recipients list so when a user deletes a message that email might be lost forever.

A searchable archive of all the talks between a company and the client is a very useful tool allowing incident tracking for people that were not directly involved in the email flow.

libcomprex library transparently handles automatic compression and decompression of files and archives located locally, online, or even in other compressed archives.

The API is similar to Cs built-in file access functions, which provides a smooth transition to libcomprex.

libcomprex can also open uncompressed files, making it a good replacement for the native file access functions.

libcomprex can currently open ar, bzip2, cpio, gzip, tar, and zip files. It supports basic archive writing in some formats. The API is very volatile, and development should be done against the CVS version.

News::Archive is a Usenet news archiving package for downloading and later accessing news articles in bulk.

It can load articles laid out in INN format, retrieve them from a running news server, or just take articles one-by-one. News::Archive module is compatible with News::Web and Net::NNTP::Server, so the articles can be shared either via the Web or via NNTP.

SYNOPSIS

use News::Archive;
my $archive = new News::Archive
( basedir => /home/tskirvin/kiboze );

# Get a news article
my $article = News::Article->new(*STDIN);
my $msgid = article->header(message-id);

die "Already processed $msgidn"
if ($archive->article( $messageid ));

# Get the list of groups were supposed to be saving the article into
my @groups = split(s*,s*, $article->header(newsgroups) );
map { s/s+//g } @groups;

# Make sure were subscribed to these groups
foreach (@groups) { $archive->subscribe($_) }

# Actually save the article.
my $ret = $archive->save_article(
[ @{$article->rawheaders}, , @{$article->body} ], @groups );
$ret ? print "Accepted article $messageidn"
: print "Couldnt save article $messageidn";

News::Archive keeps several files to keep track of its archives:

active file

Keeps track of all newsgroups we are "subscribed" to and all of the information that changes regularly - the number of articles we have archived, the current first and last article numbers, etc.

Watched over with News::Active.

history database

A simple database keeping track of articles by Message-ID. Makes access by ID easy, and ensures that we dont save the same article twice. The database chosen to maintain these is user-determined.

newsgroup file

Keeps track of more static information about the newsgroups we are subscribed to - descriptions, creation dates, etc.

Watched over with News::GroupInfo.

archive directory

Directory structure of all articles, with each article saved as a single textfile within a directory structure laid out at one section of the group name per directory, such as "rec/games/mecha". Crossposts are hardlinked to other directory structures.

Articles are actually divided into sub-directories containing up to 500 articles, to avoid Unix directory size performance limitations. Individual files are thus stored in a file such as "rec/games/mecha/1.500/1".

Each newsgroup also contains overview information, watched over with
News::Overview. This overview file goes in the top of the structure,
such as "rec/games/mecha/.overview".

You may note that these files are very similar to how INN does its work. This is intentional - this package is meant to act in many ways like a lighter-weight INN.

Usage:

Global Variables

The following variables are set within News::Archive, and are global throughout all invocations.

$News::Active::DEBUG
Default value for "debug()" in new objects.

$News::Active::HOSTNAME
Default value for "hostname()" in new objects. Obtained using
"Sys::Hostname::hostname()".

$News::Active::HASH
The number of articles to keep in each directory. Default is 500;
change this at your own peril, since things may get screwed up later
if you change it after archiving any articles!

Arcfax project is a simple archiving script that archives all of the faxes in the hylafax received directory, along with all of their log files.

You can also configure it to send the archive to another machine via SCP.

Use K7Z if you want to:
- Backup a folder to a storage location
- Create or extract a password-protected archive
- Update an existing archive quickly
Ark (2.6.3) is handy but it doesnt seem to:
- Create archives with passwords
- Extract (some) archives with passwords
- Update existing archives by default
K7Z is a simple script that attempts to fill these voids. It probably wont become a total archiving solution.
For installation instructions, see INSTALL.txt. If you encounter any problems, see ISSUES.txt and send me an email if necessary.
Enhancements:
- Beneath option: to extract below the destination
- GNU Tar: is now used to preserve file permissions (Linux)
- Explorer: improved Shell Menu layout (Windows)
- Invisible mode: i option to hide the GUI
- Verbose mode: v option for debugging purposes
- Extraction: now works properly in Slackware (Linux)
- CheckInstall: separate scripts for RedHat, Debian, Slackware (Linux)
- Makefile: possible errors prevented (Linux)
- Exception handling: possible crashes prevented
- Write access: to source dir for performance increase (Linux)
- Code structure: now modular to increase efficiency
