shell
tcsh
1. <operating system> (Originally from Multics, widely propagated via Unix) The command interpreter used to pass commands to an operating system; so called because it is the part of the operating system that interfaces with the outside world.
The commonest Unix shells are the c shell (csh) and the Bourne shell (sh).
2. (Or "wrapper") Any interface program that mediates access to a special resource or server for convenience, efficiency, or security reasons; for this meaning, the usage is usually "a shell around" whatever.

shell
[orig. Multics n. techspeak, widely propagated via Unix] 1. [techspeak] The command interpreter used to pass commands to an operating system; so called because it is the part of the operating system that interfaces with the outside world. 2. More generally, any interface program that mediates access to a special resource or server for convenience, efficiency, or security reasons; for this meaning, the usage is usually `a shell around' whatever. This sort of program is also called a `wrapper'. 3. A skeleton program, created by hand or by another program (like, say, a parser generator), which provides the necessary incantations to set up some task and the control flow to drive it (the term driver is sometimes used synonymously). The user is meant to fill in whatever code is needed to get real work done. This usage is common in the AI and Microsoft Windows worlds, and confuses Unix hackers.

Historical note: Apparently, the original Multics shell (sense 1) was so called because it was a shell (sense 3); it ran user programs not by starting up separate processes, but by dynamically linking the programs into its own code, calling them as subroutines, and then dynamically de-linking them on return. The VMS command interpreter still does something very like this.

Shell
Software that allows users to interact with the operating system. For example, a user could develop a shell script to tell the operating system to delete all files in a given directory which have not been changed in the last 3 months. Different Operating Systems have there own shell script languages.

Shell
web server/client software focused on storage, delivery, and course management. This software facilitates server/client networking that allows for student record keeping, test grading, etc. Unlike high-end authoring software, courseware shells have utilities for creating network listservs, bulletin boards, chat rooms, electronic forums, telephony, etc. These shells also facilitate lesson authoring in virtually all of the high-end authoring software listed above. Some courseware shells have more authoring capabilities than others, although none have the full authoring capabilties of the high-end authoring systems.

Shell
(1) The outermost layer of a program. Shell is another term for user interface. Operating systems and applications sometimes provide an alternative shell to make interaction with the program easier. For example, if the application is usually command driven, the shell might be a menu-driven system that translates the user's selections into the appropriate commands.
(2) Sometimes called command shell, a shell is the command processor interface. The command processor is the program that executes operating system commands. The shell, therefore, is the part of the command processor that accepts commands. After verifying that the commands are valid, the shell sends them to another part of the command processor to be executed.
UNIX systems offer a choice between several different shells, the most popular being the Cshell, the Bourne shell, and the Korn shell. Each offers a somewhat different command language.

An internet account,usually unix based,that provides the internet software for you.In contrast,SLIP,PPP,and ethernet accounts give you a connection where you run your own internet software,such as browsers,gopher,telnet,e-mail,and so on.Shell accounts run these for you ,and usually only provide text modes without graphics.Most shell accounts require some knowledge of unix commands,although many functions can be set up friendly menu structures.A shell account can be based in VMS,as well,such as Delphi internet service’s older textside access.
