Architectures: Classic AMIGAs and WinUAE.
-----------------------------------------

  MINIMUM Requirements Are:-
  --------------------------

       68EC020 CPU and 2MB CHIPRAM, 8MB Fastram, A1200(HD) with expansion.
       WinUAE Version 1.5.3, FS-UAE Version 2.4.1 minimum emulation.
       Standard OS3.1x install or better.
       ADE, the UNIX like environment, see URL below.
       (It might work on E-UAE too but untested.)

----------------------------------------------------------------------------

History.
--------

20-08-2015.
Version 1.00.00:- Original and only upload to AMINET...

----------------------------------------------------------------------------

This is the start of some very simple UNIX style shell scripts for use with
the ADE, UNIX like, suite, found here:-

http://aminet.net/package/dev/gcc/ADE

The idea is to give we lowly users of an A1200(HD) with memory expansion a
taste of the UNIX environment along with the power of the UNIX shell.

The shell is 'ksh' and appears to be ~ksh88~ as floating point arithmetic
does not exist in this version. As the 'bc' and 'dc' commands are not part
of ADE then floating point maths will have to done through 'awk'. In the
ADE implementation of this UNIX suite 'awk' has some foibles but they can
be overcome.

This first program produces a stand alone WAVE file that can be played on
just about anything that can play music. It is created inside the '/home/'
drawer of ADE. It is a !KHz sinewave WAVE file that lasts about 1 second.
The filename generated is 'sinewave.wav'.

This was written on a Macbook Pro circa August 2012, OSX 10.7.5 and run
through FS-UAE in full screen mode. Also tested on WinUAE, on Wndows 8.1.
(Designed for the above minimum requirements.)

Just download the script 'ADE_beep.sh.txt' into the ADE '/home/' drawer,
rename it to 'beep.sh', change the access rights 'chmod 755 beep.sh' and run
from the '/home/' drawer as './beep.sh' without the single quotes...

This and other small snippets will be DEMO scripts to show the power of the
UNIX shell at around the time of the A500 appearance.

Current UNIX environments ARE more sophistacted but this script still works
on them and that makes just another reason why the UNIX shell is so cool.

Keep an eye open for more small snippets of UNIX shell code on AMINET to
support the great work done by the guys that have given you the environment
that runs UNIX shell code...

Enjoy finding simple solutions to often very difficult problems... ;o)

    Testing Evaluation:-
    --------------------

    All emulated and Classic AMIGA test conditions were/are running standard
    OS3.1x and using standard ~topaz 8~ fonts throughout.

    I have no idea what strange configuration setups will create so refer
    to the ~The Legal Stuff~ above.
