Business Shell (BUSH) can be used as interactive command shell, scripting language with a source code debugger, a database client and a web template engine. With third-party support for the ABEE standard for Java Virtual Machine and .Net, BUSH is an all-in-one replacment for BASH, PHP, J2EE, Ruby, Python, PERL and PSQL.
There are many shells, interpreters and languages available. Virtually without exception, they are incompatible with one another. Whats the point of learning a tool that, no matter how sophisticated it is, leaves your source code stuck with that particular tool. You want to do scripting, so you use Python or Scheme.
You want to do reporting, so you use Perl. You want to write a script, so you use Bash. You want to write an applet, so you use Java. To be a programmer these days, you need to be fluent in a dozen different languages. You would be making more money if you got a job at the United Nations.
The Business Shell is different. Its based on a language called AdaScriptTM, a subset of one of the most powerful languages available for Linux today. Ada 95 is a GCC supported language so any project you write in Bush is immediately portable to any machine that GCC runs on. In other words, virtually everything.
And it means that Bush scripts can be compiled using GCC and everyone knows that GCC is superior to most commercial compilers. If thats not enough, using the JGNAT open source compiler, you can even compile your Bush scripts into actual Java bytecode. There is another tool, A#, that will compile scripts into .NET byte code Things dont get much more platform-independent than that.
But Bush does more than just create scripts, executable programs and Java applets. Its a powerful computer language on its own able to do complex math, manipulate files, generate reports and able to do network programming. Bush will let strings grow as big as you need without worry of a running out of buffer space. And a number of built-in packages will let you do everything from compute trig functions to connecting to a web server.
But best of all, Bush is easy. Perl claims to be easy. Easily like riding a bicycle backwards in the middle of a thunderstorm. Bush is easy to read, easy to understand. You know exactly what a script does without having to have a reference book beside you at all times
Bush doesnt run your programs outright. First it examines them, compresses them, and converts them into intermediate code. (Thats "byte code", to you Java developers.) Bush optimizes the program for the best possible performance. It also takes the time to verify your program will run before attempting to execute the first line.
And if you make to typing mistake, Bush will let you know before running your program. Theres no need to worry that your typo will be a valid command like it would be in most other languages. Bush works for you, not against you.
One tool for all solutions.

CD Shell is a scriptable menu system that provides the ability to create interactive multi-boot optical discs. It will make PC-bootable compact discs or DVDs that can select from several program loaders or kernels located on the disc, or boot from other local disk drives that are attached to the system.
This utility is based heavily on concepts pioneered by Bart Lagerweij in his great program Diskem1x. CD Shell provides similar functionality to Diskem1x along with many new original features, such as an advanced scripting language, graphics, and mouse support. It also has the ability to interface with other great programs such as isolinux/memdisk, Ranish Partition Manager, and Memtest86+.
CD Shell is free for non-commercial use. The program and its source code is distributed under the NASM License. The distribution and use of some optional components is restricted by their respective licenses.
Enhancements:
- changed behavior of display.message to interpret a backslash as a single-character quote if not recognized as an escape sequence (suggested by Erwin Veermans of the Ultimate Boot CD project)
- isolinux patches as suggested by Charles Appel of the Ultimage Boot CD project
- patched a bug in isolinux that would display some garbage characters when loading a kernel (just before Ready)
- changed behavior for the display command to not show a splash screen unless isolinux was invoked with an empty command line
- incorporated changes to chooser script
- allow onEscape action when user quits the menu
- allow per-item exececute-on-select commands
- fixed a bug where text in the message window wasnt being updated correctly

Group Shell is a tool to aggregate several remote shells into one. It is used to launch an interactive remote shell on many machines at once. Group Shell is written in Python and requires Python ≥ 2.4.

There is a control shell accessible with Ctrl-C that is used to list some information about the current remote shells. It also allows common terminal manipulations like sending a Ctrl-C, Ctrl-Z, Ctrl-D …

The prompt shows the number of listening shells and the number of active shell. A shell is said to be listening if its prompt has returned and it is accepting commands, active shells are those whose connection is still alive. Shells can be individually enabled and disabled.

Here is the transcript of a sample session:

[g ~/gsh]$ ./gsh.py machine{0-9}

[10/10]> date

PShell provides a small yet powerful UI to a customized secured shell in Perl.

PShell is a secured shell written entirely in Perl. It has a curses menu interface and a rudimentary commandline interface. The shell has been secured by being placed into a chroot jail and allowed only certain commands or programs to be used (flexibility is added by a configuration file).

The PShell is a menu-driven and secured shell for use with SSH on a linux/UNIX-derivative operating system. Its menu design was taken from another popular menu-driven shell, loginshell.pl.

Although it may appear similar, much code has been added and removed, and with the help of a chroot environment it has become powerfully secured. All in Perl, of course, and liscenced under the GNU GPL.

The original developer of the loginshell program had no such liscence (even though his website differs), which is why i didnt modify much of his existing code where i could.

True3D*Shell is an open source 3D desktop environment that allows users to experience 3D browsing in a virtual reality universe where information is organized in bubbles connected by pipes. True3D*Shell is based on POSIX, Win32, FreeGLUT, OpenGL and MQ4CPP, and runs on IA32 and IA64 SMP platforms.
A user can browse local and remote filesystems and download and run selected files. It includes a robot mode that allows you to browse automatically.
Main features:
- Shell : provides access to the kernel services
- Desktop environment : offers a graphical user interface (GUI) solution to operate a computer
- Avatar : provides a fantastic representations of a persons self with witch user can explore the virtual universe.
- Virtual Reality : users can interact with a virtual environment either through the use of standard input devices such as a keyboard and mouse, or through multimodal devices.
- MVC paradigm : is a software architecture that separates an applications data model, user interface, and control logic into three distinct components.
- Multithreading : Threads are a way for a program to split itself into two or more simultaneously running tasks. Multiple threads can be executed in parallel on many computer systems.
- Grid computing : provides the ability to perform higher throughput computing by taking advantage of many networked computers to model a virtual computer architecture that is able to distribute process execution across a parallel infrastructure.
- MOM paradigms : Message Oriented Middleware is a category of inter-application communication software that relies on asynchronous message passing as opposed to a request/response metaphor.
