I have heard that there is a Shell called "zsh" on UNICS-systems. ZShell
has nothing to do with it, because it tries to be AmigaDOS compatible,
not just another UNICS shell clone. The compatibility is, of course, not
100%, if you need that use the original AmigaDOS Shell. So ZShell has some
differences, that give the special feeling of it.

The first main advantage of ZShell is its power/size ratio. In just 32K
there are all often needed commands (like list,copy etc.) and some not
so often needed, which do not increase size much.

The second main advantage is the Filename completion (short: FNC) and the
review buffer. FNC is like those shells on UNICS and can therefore be
controlled fully with the keyboard. No annoying filerequesters pop up,
that make it neccessary to change from keyboard to mouse.
Nevertheless you can use ZShell with (memory hungry and slow) console
handlers like  KingCON .

Third, I tried to make using ZShell as easy to use as possible. Not like
UNICS shells which have thousands of options you will never keep in mind.

Fourth thing is script file execution. ZShell itself supports only the
basic stuff to execute scripts, because if you need a more complex
construction you can use ARexx or another programming language.
ZShell was never intended to be a substitute for a programming language !
You can use scripts made for AmigaDOS shell without problems, because
the command EXECUTE uses AmigaDOS to execute it.
