Free .rar software for linux

cbrPager project is a no-nonsense, simple to use, small viewer for cbr (comic book archive) files. As it is written in C, the executable is small and fast. It views jpg (or jpeg), gif and png images, and you can zoom in and out.
Main features:
- Simple usage: A navigation bar stays on top of the pages.
- It works on any RAR-compressed image archive - normally the extension would be .cbr or .cbz, but other extensions work too.
- Advance/backup pages, and go to the begin and end.
- Zoom in and zoom out (10% steps) and return to 1:1.
- It should manage jpeg (jpg), png and gif images.
- A configuration window permits defining a few slightly more advanced tricks:
- When advancing go to the top of the next page (or bottom or stay where you are.)
- Same possibilities when paging backwards.
- Remember the last directory visited on startup, or always start in a defineable directory.
- Determine the initial size of the pager.
- Define where the navigation bar should be and its orientation.

Jeremiah is a set of PHP scripts that aims to make regular downloads a completely automatic procedure.

At the moment, only a addon for downloads via BitTorrent is available.
Main features:
- Pluginsystem for automatic downloads.
- (currently there is only a plugin for the download of torrents)
- Support for multipel checksum file types.
- (Currently only PAR, PAR2, SFV and Torrent are preconfigured but any fyletype supported by cfv can be used.)
- Support for multipel compressed file types.
- (Currently only rar, 7z and rar are preconfigured but any other filetype and decompression software can easily be added.)
- Recrusive scanning of multipel incoming directories
- Automatic detection of redundant checksum files.
- Semi-Smart file verification.
- (Downloads arnt verifyed until all files have been completly downloaded.)

psArchive is a PHP 5 extension designed to provide an easy to use interface for manipulating all the most common archive files used in Web projects at high speeds and workloads.
psArchive is especially designed for Web applications that need to understand, to produce, or even edit archives in order to function.
Main features:
Supports archive *editing*! You can add, remove, rename and copy files, you can change file contents, attributes and modification time, you can create new files and directories, *all* right inside the archive before output.
Supports the following archive formats:
- 1. ZIP (single volumes);
- 2. TAR (tarball tape archive);
- 3. GZ (Gzip compressed format);
- 4. BZ, BZ2 (Bzip/Bzip2 compressed format);
- 5. TAR.GZ, TGZ (Gzipped Tarball);
- 6. TAR.BZ2, TAR.BZ, TBZ2, TBZ (Bzipped Tarball);
- 7. Other formats can be supported on demand, such as RAR or ACE support (since these formats are uncommon in web environments we decided not to include them in order to keep the extension size as small as possible);
Configurable buffer storage for optimized and threadsafe memory handling:
- 1. In raw memory (for optimized speed);
- 2. In compressed memory (normal operation);
- 3. On disk (for optimized memory consumption);
Provides 2 functions for extremely fast in memory data compression / decompression using LZF algorithm. These functions correctly compress / decompress data blocks far greater than 1024 bytes;

Closebracket let you define multiple shell actions in a single command to speed up the typing of the most repetitive shell commands. The command name of Closebracket is `] and `][, thats because these characters are near the "Enter" key and it is easy to type them fast.
`] stands for "primary fire", while `][ is the secondary one.
After few days youll find Closebracket very additive.
Closebracket is dedicated to the God of Laziness, may He bless you (when He feels to do it).
Installation:
Download the latest tarball from http://www.freaknet.org/alpt/src/utils/closebracket/tarball/
Use the ./install.sh script to install it. It will copy the files in ~/.closebracket and add some aliases in ~/.bashrc
Usage:
Since too many words are needed to describe all the actions that are included
by default, Ill show you them by examples.
Keep in mind that you can tune them and define your own actions by editing the
~/.closebracket/closebracket.conf file.
In the first line closebracket is used to activate an action. The second line is the equivalent of that action.
##
### Basic shell movements
##
$ ]
$ ls # ls current directory
$ ][
$ cd # cd to home
$ ] dir/
$ cd dir/
$ ][ dir/
$ ls dir/
$ ][ file
$ cat file
$ ][ non_existent_file
$ vim non_existent_file
##
### Remote shells
##
$ ] shell # With closebracket you keep the list of the
$ ssh shell.expanded.org # name of your remote shells in
# ~/.closebracket/shells. In this case we put
# "shell.expanded.org" in the list.
# Closebracket searches the closest match with
# the word you typed and then use that as the
# remote shell hostname.
$ ] shell:file
$ vim scp://shell.expanded.org/file # Beware of the Vim power
$ ] user@shell:/path/file
$ ] scp://user@shell.expanded.org/path/file
$ ][ shell:dir/
$ scp -r shell.expanded.org:dir/ .
$ ][ shell:dir/ local_dir/
$ scp -r shell.expanded.org:dir/ local_dir/
$ ][ file1 file3 dir1 dir3 shell:remote_dir/
$ scp -r file1 file3 dir1 dir3 shell.expanded.org:remote_dir/
##
### URLs, mail addresses and algebra
##
$ ] http://URL
$ firefox http://URL
$ ][ http://URL
$ wget http://URL
$ ] email@address.org
$ mutt email@address.org
$ ] 2*2+1-21%2^2
$ echo 2*2+1-21%2^2 | bc -l
$ ] "2*2+1*sqrt(400)/l(2)^2" # if you want to use parentesis you
$ echo "2*2+1*sqrt(400)/l(2)^2" | bc -l # have to use quotes ;(
##
### File type based on extension
##
$ ] pack.tar.gz # This works for .tar, .tar.bz2,
$ tar xfz pack.tar.gz; cd pack/ # .tar.gz, .tgz, .zip, .rar
# If the directory unpacked isnt the
# same of the filename of the tarball
# it understands that ^_-
$ ] movie_or_mp3.ogg # .avi, .mp3, .wav, .wmv, ...
$ mplayer movie_or_mp3.ogg
$ ] image.jpg # .jpg, .png, .gif, ...
$ gqview image.jpg # if you are in tty it launches `seejpeg
$ ][ image.jpg
$ gimp image.jpg
$ ] file.htm # .htm, .html, .php, ...
$ firefox file.htm # if you are in tty it launches `links instead.
Enhancements:
- ] file:line is now equivalent to executing "vim file +line".
- The "untarra script will now repair broken tar/zip/rar archives, i.e. archives that would decompress files in ./.
