Extracting tar.bz2 files in Linux, command line:
tar jxvf file.tar.bz2
- j : filter the archive through bzip2 [ 1 ]
- x : extract files from an archive
- v : list the files processed
- f : use archive file
The command extracts the contents of a bzip2 compressed archive to the current directory.
Tar creates an archive of one or several files. Then bzip2 is used to compress it. Or both processes are made at once by tar only, with corresponding options employed. The duality of nature - archived and then compressed - is reflected in the extension of the file ("tar.bz2") and requires two procedures to be performed while extracting: decompressing and unpacking. Hence both j (decompress it) and x (unpack it) in the command.

Jump to: Arachne web browser. Installing and setting up for internet connection via Ethernet Arachne web browser. Installing and setting up for dial-up internet connection Versions : Configuration and use : Download links Arachne is a full-screen graphical web browser for DOS on PC computers. Originally developed by Michael Polák. First release - 22th December 1996. The last Arachne version by Arachne Labs was released on 22th January 2001. Arachne source code was opened in November of 2003 and the subsequent versions are released under GNU GPL license. Arachne is distributed as a software suite containing, besides web browser, built-in e-mail client, FTP, internet connection wizard, WAV files player. More add-ons are available: image viewer, PDF, file managers, mplayer, Telnet client, IRC and more. Arachne supports Windows-1251 and KOI8-R Cyrillic after additional packages are installed. Internet connection is via serial ports (COM) and Ethernet. There are also Arachne for Linux / SVGAlib. Versions GPL versions of Arachne. The main line of Arachne development. Major changes and updates take place within its framework. Maintained by a group of enthusiasts who also develop GPL version for Linux / SVGAlib. Arachne Labs versions. Arachne Labs, xChaos software initially, were the main structure engaged in development of Arachne until 2003, when Arachne source code was opened and the GPL versions of the browser became the main line. The last Arachne Labs version was released on 22th January 2001: Arachne 1.70 Release 3. Ray Andrews version. A GPL Arachne variation. PTS-DOS version. Similar to the corresponding versions of Arachne, but to some extent integrated with the PTS-DOS distribution. DR-WebSpyder. Based on Arachne. Basically - different web browser, for which Arachne is just an ancestor. Later the browser was renamed as Lineo EmBrowser. Configuration and use Arachne web browser was created in DOS and for DOS (the Linux version stands somewhat apart). Therefore, even though Arachne will run under many versions of Windows, Windows XP for instance, it is working under DOS when Arachne qualities are revealed best. Arachne web browser works in all major DOS variants, for example MS-DOS, FreeDOS or PTS-DOS. System requirements are low. The minimum: 80x86 CPU, 500 KB DOS base memory, 1 MB XMS/EMS memory, 512 KB SVGA video, 5 MB HDD space. Although requirements for using maximum screen resolution, maximum color depth are higher. But in this case too they are extremely small by today's standards - 486, better Pentium I computer, 640 KB base memory, 8+ MB XMS/EMS memory, 2+ MB SVGA video. Yet it depends - using 640x480 screen resolution, installing Arachne on RAM disk let to have Arachne running quite well on 386 CPU computer; if only there are enough of RAM and video adapter capabilities. Besides traditional hard disk installation, DOS LIVE CD by Roman Karpach may be used ( www.fdd5-25.net/doslivecd ), where Arachne web browser is among the software present. The characteristics of Arachne web browser installation process make the main settings be set right from the beginning. These settings for the most part are the responsibility of operating system on computers running Windows, Mac OS X or Linux, but in DOS Arachne browser takes care of everything itself.
FTE : JED : MinEd : Nano : MS-DOS Editor Initially, all text editors did not have a graphical interface. And work with text almost from the outset was one of the main types of user activity on computer. With the invention and spread of low-level and especially high-level programming languages, text editor has become an important working tool of professionals. Then, other users had to use text editors for their daily tasks. So by the time the programs with GUI started to be wide spread, the concept of text editor was already well developed, there were mature, well-designed and implemented specimens of applications for text editing without graphical user interface. Why the text-based versions coexisted with GUI-based ones for very long and still graphical user interface programs have not replaced the console / text-based applications. While the average user is not aware of their existence, he / she does not know the power of vim or emacs, often even MS-DOS Editor, built in all the 32-bit versions of Windows is unknown, none the less, console text editors continue to exist and be developed. As it is the case with the text web browsers, the main line of text-based text editors development is in Linux and other *nix systems world. But under Windows as well, there are several interesting applications. FTE - / home page / Console text editor. Version for Linux, some other *nix systems, DOS, Windows, OS/2. Syntax highlighting support for: C, C++, Java, Perl, Sh, Pascal, SQL, Assembly, PHP, Python, REXX, Ada, Fortran, IDL, LinuxDoc, TeX, TeXInfo, HTML, etc. ASCII table. Various facilities for coding and errors handling. Copying words, characters or text blocks is in the same mode and by the same keyboard shortcuts (except Ctrl+A) as in major Windows text editors with graphical user interface - plus, there may be other variations.
