- No... a command shell is not a part of the OS... it is
- an application (even if you won't go far without it..)
- (see for example Tannenbaum book about OS, which -i think- gives
- a good idea of what is an OS..)
- As an example, the C-Shell and the Bourne shell belongs to unix
- environnement, but not to unix itself (ie whatever shell you run,
- your OS is unix and nothing else)
- A command shell is a program that gives the user an access to the OS.
- An OS is a program that gives other programms an access to the machine
- ressources (at least this is what i believe...)
