Designers or artists translate what they have inside their heads directly into another (programming) language which the computer understands: the strange manual click-and-drag go-between is eliminated. This way the design process becomes a semantic process.

Users can create programmed scripts that, when executed, create visual output. One part of the application's interface is the empty output canvas, the other part is a programming interface. There are no menus with predefined filters, no buttons, and basically nothing to drag and drop. NodeBox offers a totally different approach. This is what we could call a manual approach to the graphic design process: users need their hands to design. Designers can drag and drop images or text on the canvas, stretch things with the mouse, rotate elements, select predefined filters from menus, click action buttons. Graphic design software, applications such as Adobe PhotoShop and Adobe Illustrator, commonly relies on the mouse as interaction tool.

The Shell Scripting Examples section of the tutorial adds additional examples in particular of how the Bash shell provides additional useful functionality over the standard Bourne shell.

This tutorial covers all shell scripting basics. This tutorial restricts itself to being Bourne shell compatible, to provide a baseline. Many variants have come and gone over time (csh, ksh, and so on). Steve Bourne wrote the original Bourne shell which appeared in the Seventh Edition Bell Labs Research version of Unix.
