|

|

<p> </p>
|
||||
|
||||
<p><font face="Times">The GNO shell is an integral part of the
|
||||
GNO Multitasking Environment (GNO/ME). The GNO shell provides the
|
||||
interface between the user and the GNO Kernel. While both work
|
||||
together, the jobs they perform are quite different. This manual
|
||||
documents the functions of the shell.</font></p>
|
||||
|
||||
<p><font face="Times">The user interacts with the shell through a
|
||||
command-line interface. Command-line interfaces provide a unique
|
||||
way of interacting with the operating system. Unlike GUIs
|
||||
(Graphical User Interfaces), with which you are already familiar
|
||||
with by using programs such as the Finder and ShrinkIt! GS, all
|
||||
commands are typically entered using the keyboard. The shell
|
||||
interprets commands and passes them to the kernel for control and
|
||||
execution.</font></p>
|
||||
|
||||
<p><font face="Times">The command-line interface will be
|
||||
unfamiliar to some people However, once the command-line
|
||||
interface has been mastered, the user should have no difficulty
|
||||
using any current or future GNO applications. Those of you
|
||||
already familiar with Unix interfaces, such as the C shell,
|
||||
Bourne shell, and Korn shell, or the ORCA shell on the Apple
|
||||
IIGS, will begin to realize the advantages which GNO/ME is able
|
||||
to provide.</font></p>
|
||||
|
||||
<p><font face="Times">The way this manual is presented allows the
|
||||
complete beginner to simply work through the chapters in a
|
||||
chronological prder. Chapter 2 familiarises the user with
|
||||
entering basic commands whereas the more powerful GNO/ME features
|
||||
are introduced in Chapter 3. Chapter 4 documents the commands
|
||||
which are built into the GNO Shell and Chapter 5 explains shell
|
||||
variables which give the user control over how thier installation
|
||||
functions.</font></p>

<p><font face="Times"><b>Customizing the Shell Environment</b></font></p>
|
||||
|
||||
<p><font face="Times">When <b>gsh</b>, the implimentation of the
|
||||
GNO Shell, is executed, it reads in and processes the <i>gshrc</i>
|
||||
file. This file contains start-up instructions for the shell,
|
||||
which can be used to customize the operation of the shell and
|
||||
other aspects of the system. It is created by the GNO Installer
|
||||
during the installation process.</font></p>

|

<p><font face="Times">When you install GNO/ME, the GNO installer
|
||||
knows where to find the GNO utilities and any ORCA utilities you
|
||||
may have. Unfortunately it does not know where all the other
|
||||
utilities and applications that you may wish to use are located.
|
||||
It is therefore necessary to edit the setup file in order to tell
|
||||
the GNO shell where these programs are on your hard disk.</font></p>
|
||||
|
||||
<p><font face="Times">The setup file, <i>gshrc</i>, is located in
|
||||
the /usr directory of the path where you installed GNO/ME. You
|
||||
can use any text editor from the desktop to edit the <i>gshrc</i>
|
||||
file, or if you are already familiar with the editor <b>vi</b>
|
||||
you can use this utility after launching the GNO kernel.</font></p>
|
||||
|
||||
<p><font face="Times">Line 9 is the statement that we are
|
||||
concerned with. <b>Hard </b>represents the name of your
|
||||
particular hard drive volume where you have installed GNO/ME.</font></p>
|
||||
|
||||
<p><font size="2" face="Courier">set path=":hard:gno:bin
|
||||
:hard:gno:usr:bin" line #9</font></p>
|
||||
|
||||
<p><font face="Times">You will see that spaces have been inserted
|
||||
between pathnames. The space is the pathname separator and the
|
||||
colon has been used as the path delimiter for this specific
|
||||
variable, PATH. As an exercise, add your system directory to this
|
||||
statement. Line 9 should now look like this:</font></p>
|
||||
|
||||
<p><font size="2" face="Courier">set path=":hard:gno:bin
|
||||
:hard:gno:usr:bin :hard:system"</font></p>
|
||||
|
||||
<p><font face="Times">What you have just done allows the GNO
|
||||
shell to find the <b>Finder</b> application. Now go ahead and add
|
||||
any pathnames that hold utilities or applications that you will
|
||||
use frequently from GNO/ME. It should also be noted that it is
|
||||
possible to have more than one pathname containing EXE, SYS16, or
|
||||
EXEC files; this is impossible under ORCA. The PATH variable is
|
||||
discussed thoroughly in Chapter 5.</font></p>
|
||||
|
||||
<p><font face="Times">For now, the remaining lines of the <i>gshrc</i>
|
||||
file do not need editing. As you gain an understanding of the
|
||||
system you may wish to make further changes to the <i>gshrc</i>
|
||||
file. Make sure you save the file before you exit the editor.</font></p>
|
||||
|
||||
<p><font face="Times">It is possible to modify these instructions
|
||||
while the GNO shell is active, but any changes will be lost upon
|
||||
exiting <b>gsh.</b> If you wish the changes to remain effective
|
||||
for the next session you must add them to the <i>gshrc</i> file.</font></p>
|
||||
|
||||
<p><font face="Times">By customizing the <i>gshrc</i> file it is
|
||||
possible to make the GNO environment more like U</font><font
|
||||
size="2" face="Times">NIX, </font><font face="Times">the ORCA
|
||||
environment, or something completly different. Customization of
|

the GNO environment leads to greater user productivity.</font></p>

|
||||
|
||||
<p><font face="Times">A command consists of two parts: a name and
|
||||
its arguments. The command name is the name used to start the
|
||||
command. The name is usually the name of a file which can be
|
||||
executed. The only exceptions are commands which are built-in to
|
||||
the shell. These commands are documented in Chapter 4 <b>Built-In
|
||||
Commands</b>. Any shell utility command with a filetype of EXE,
|
||||
SYS16, or EXEC, can be executed in this fashion. The command name
|
||||
must be separated from the command arguments with a space.</font></p>
|
||||
|
||||
<p><font face="Times">The command arguments are parameters that
|
||||
the command takes as data to work with (In Applesoft BASIC,
|
||||
"</font><font size="2" face="Courier">HELLO WORLD</font><font
|
||||
face="Times">" would be an argument for the </font><font
|
||||
size="2" face="Courier">PRINT</font><font face="Times"> command).
|
||||
Command arguments are separated from each other with a space.
|
||||
Note that although arguments extend the usefulness of a command,
|
||||
not all commands have arguments. Any arguments entered after the
|
||||
command will be passed by the shell to the program when it starts
|
||||
exectuting. </font></p>
|
||||
|
||||
<p><font face="Times">The examples below use the following
|
||||
commands:</font></p>
|
||||
|
||||
<p><font size="2" face="Courier"><b>qtime</b></font><font
|
||||
face="Times"> displays time in English text.</font></p>

|

<p><font face="Times">At the simplest level the user enters
|
||||
commands to the shell by typing them on the keyboard. <b>Gsh</b>
|
||||
includes a command-line editor to help the user enter and edit
|
||||
commands. The editor also provides a way to modify and execute
|
||||
previous commands. Additionally the editor can help complete the
|
||||
names of commands, filenames and variables.</font></p>

<p><font face="Times">Below is a complete description of the

functions of the command-line editor with short examples

|
||||
<p><font face="Times">Throughout the examples the underline

character, "</font><font size="2" face="Courier">_</font><font

Open Apple key and the term <i>word</i> is used to indicate a
|

string of characters consisting of only letters, digits, and
|

underscores. To the right of a editing key entry is the </font><font

<p><font face="Times">It should be pointed out that at this stage

that the user should not be concerned with what the actual

describe commands that exist within the shell itself. These

already loaded into memory. Files of type "EXE", on the

other hand, must be loaded into memory by <b>gsh</b> and
|

executed. If an EXE command is executed again, it might, again,

have to be loaded into memory. This results in longer execution

time for the program.</font></p>

The term "</font><font size="2" face="Courier">SIGNAL</font><font

"..." means the command accepts multiple arguments of

the same type as the argument before the "..."

<p><font face="Times"><b>Reporting Bugs</b></font></p>
|
||||
|
||||
<p><font face="Times">In any large piece of computer software
|
||||
such as the GNO/ME system, bugs are sure to turn up, no matter
|
||||
how much testing is performed on the software before it goes out
|
||||
the door. If you discover a bug in GNO/ME, we'd like to hear
|
||||
about it. There are several things we require, however, to make
|
||||
bug reports useful to us.</font></p>
|
||||
|
||||
<p><font face="Times">First of all, we need a complete
|
||||
description of your computer system; how much RAM, what cards, in
|
||||
what slots, what type of disk storage, etc. This information is
|
||||
very important in tracking down hardware-dependent bugs. Also, we
|
||||
need to know the version numbers of the software involved; the
|
||||
GNO Kernel, the GNO Shell, and any utilities.</font></p>
|
||||
|
||||
<p><font face="Times">Second, we need a step-by-step description
|
||||
of how to duplicate the bug. If this requires writing down
|
||||
individual keystrokes, then we need it. Only in this way can we
|
||||
decide whether the bug is hardware dependent or global.</font></p>
|
||||
|
||||
<p><font face="Times">You can send bug reports to any of the
|
||||
electronic mail addresses listed on the 'Credits' page, or by
|
||||
mailing a disk containing a description of the problem and the
|
||||
necessary software and files to the Procyon address.</font></p>
|
||||
|
||||
<p><font face="Times"><b>User Projects</b></font></p>
|
||||
|
||||
<p><font face="Times">If you're working on a project which
|
||||
utilizes GNO/ME in some way, we'd like to know about it. Just
|
||||
contact us by mail, phone, or whatever is most convenient for
|
||||
you, and tell us about your project. If possible, we'll
|
||||
coordinate your efforts with those of other programmers. If we
|
||||
really like your project and think it may be useful to others, we
|
||||
may include it on the next GNO/ME distribution!</font></p>
|
||||
|
||||
<p><font face="Times"><b>Software Piracy</b></font></p>
|
||||
|
||||
<p><font face="Times">If you copied GNO/ME from someone and are
|
||||
now reading this, take a moment to reflect on what you've done.
|
||||
GNO/ME is a project that has consumed around three man-years of
|
||||
effort, huge amounts of money, and a lot of grief on our part.
|
||||
The kernel alone consists of over 18,000 lines of source code;
|
||||
the shell and utilities make up another twenty to thirty thousand
|
||||
lines.</font></p>
|
||||
|
||||
<p><font face="Times">Is it right that you're now benefiting from
|
||||
our effort without any just compensation to the authors and
|
||||
Procyon, Inc.? We are Apple II programmers born, bred and raised
|
||||
in the spirit of the machine; we love to program it, and probably
|
||||
always will. But if we cannot make enough money to make it
|
||||
worthwhile to continue work on GNO/ME, then we won't; because by
|
||||
worthwhile, we mean not only food on the table, but resources for
|
||||
expansion; expansion of our IIgs product line and support to IIgs
|
||||
owners being abandoned by the rest of the industry. In short,
|
||||
support us and we'll support you.</font></p>
|
||||
|
||||
<p><font face="Times">GNO/ME is very inexpensive when you
|
||||
consider what it allows you to do, and what it will allow you to
|
||||
do when software development for GNO/ME starts full-swing. And
|
||||
it's a small price to pay indeed for our loyalty to you, the IIgs
|
||||
owner.</font></p>
|
||||
|
||||
<p><font face="Times">To all you GNO/ME purchasers out there:
|
||||
thank you very much. We will continue to provide you with new
|
||||
IIgs products until our hair and teeth fall out, and our fingers
|
||||
are too frail to type the keys (and even then, with Easy Access,
|
||||
we might crank out a program or two). We hope you will be
|
||||
sufficiently impressed with the system to recommend it to others.</font></p>

|

|

<hr>
|
||||
|
||||
<p><font size="6" face="Times">Preface</font></p>
|
||||
|
||||
<p><font face="Times">Computers are tools. The flexibility of a
|
||||
tool determines how useful it is. Early computers were much like
|
||||
the one this software was written for: the Apple IIgs. They could
|
||||
only run one program at a time, and their usefulness was limited
|
||||
to what the particular program the user was executing offered. In
|
||||
the late 1960's, a team of researchers at AT&T began
|
||||
developing the UNIX operating system. The UNIX design was
|
||||
partially based on the premise that most programs are I/O bound,
|
||||
that is, most of the time the program executes is spent waiting
|
||||
for user input or other I/O operations. While one program is
|
||||
waiting for I/O, why not allow another program to execute? This
|
||||
is what they did, and the result was one of the most successful
|
||||
computer operating systems ever created.</font></p>
|
||||
|
||||
<p><font face="Times">The Apple IIgs, like the Macintosh it is
|
||||
modelled after, provides very limited multitasking abilities in
|
||||
the form of desk accessories (NDAs). The programs in the NDA menu
|
||||
are available in whatever application you use as long as it
|
||||
follows Apple's guidelines. However, there are many graphics
|
||||
based programs that don't support NDAs, and in addition there is
|
||||
a wealth of software that has been developed for the Byte Works'
|
||||
ORCA environment. This environment is mainly text-based, and thus
|
||||
makes access to NDAs impossible. As if that wasn't enough, it's
|
||||
very difficult to write an NDA to allow the application to keep
|
||||
running concurrently. So the benefits are lost, and we're back at
|
||||
ground zero.</font></p>
|
||||
|
||||
<p><font face="Times">Enter the GNO Multitasking Environment.
|
||||
What was once just dreamed about is now a reality. GNO/ME
|
||||
provides an environment that is almost entirely compatible with
|
||||
software developed for the ORCA environment. But GNO/ME also
|
||||
provides a wealth of new abilities, lots of new ground for
|
||||
developers and users alike.</font></p>
|
||||
|
||||
<p><font face="Times">Before we begin describing, we'd like to
|
||||
respond to those who say such a multitasking system isn't
|
||||
possible on the Apple IIgs. Obviously it is: you hold it in your
|
||||
hands. Some say the Apple IIgs isn't powerful enough to make
|
||||
multitasking useful. We point out that the Apple IIgs is much
|
||||
more powerful than the first computers UNIX was designed to run
|
||||
on; they only had 64K of real memory, and were 16 bit machines.
|
||||
Some ask why you'd ever need to run more than one program at
|
||||
once. These are the same people who asked why we'd ever need more
|
||||
than 64K of memory, or more than 140K of storage on disks (end
|
||||
soapbox).</font></p>
|
||||
|
||||
<hr>
|
||||
|
||||
<p><font size="6" face="Times">Introduction</font></p>
|
||||
|
||||
<p><font face="Times">The GNO Multitasking Environment provides
|
||||
pre-emptive multitasking. Many programs can be executing at the
|
||||
same time; each is called a 'process'. Each process is allowed to
|
||||
run for a short period of time (1/20th of a second on average).
|
||||
When its time runs out, the current process is set aside and
|
||||
another one chosen to run next. This cycle continues until there
|
||||
are no more processes left (i.e. when you exit GNO/ME). Starting
|
||||
up processes to run 'in the background' is a simple matter of
|
||||
adding a few characters to the shell commands.</font></p>
|
||||
|
||||
<p><font face="Times">GNO/ME provides a shell that takes full
|
||||
advantage of the multitasking ability provided. The most
|
||||
important feature of the shell is job control (starting,
|
||||
terminating, and suspending processes). But the shell also
|
||||
provides power never before seen on the Apple IIgs. The ability
|
||||
to choose files by 'wildcard' has been around for a while, but
|
||||
the GNO Shell takes this to a new level with 'regular
|
||||
expressions', a very powerful yet simple programming language.
|
||||
Other benefits of the GNO shell are too numerous to mention. (see
|
||||
the <i>GNO Shell User's Manual </i>for details).</font></p>
|
||||
|
||||
<p><font face="Times">In addition to being compatible with the
|
||||
ORCA system, GNO/ME is a very powerful programming environment.
|
||||
Available to the programmer are all the calls needed to control
|
||||
processes, support Inter-Process Communication, and other tools
|
||||
needed in a multitasking environment. </font></p>
|
||||
|
||||
<p><font face="Times">GNO/ME also boasts the first completely
|
||||
consistent method for accessing serial and console I/O. The IIgs
|
||||
TextTools have been incredibly enhanced to provide a truly
|
||||
all-encompassing interface for serial, console, and IPC
|
||||
applications. Imagine being able to attach terminals to your GS,
|
||||
and have a useful shell in each one. Multiuser BBSs, remote
|
||||
dial-ups, UUCP or SLIP that doesn't take over your computer- the
|
||||
applications are endless!</font></p>
|
||||
|
||||
<p><font face="Times">With all this talk of shell utilities, have
|
||||
desktop users (users of programs like AppleWorks GS) been left
|
||||
behind? Absolutely not. GNO/ME doesn't allow more than one
|
||||
desktop program to run concurrently, but it DOES let you run a
|
||||
desktop program with as many text applications as you like. In
|
||||
other words, no functionality is lost from the IIgs by using
|
||||
GNO/ME.</font></p>
|
||||
|
||||
<p><font face="Times">Finally, the GNO Multitasking Environment
|
||||
comes with a large number of free utilities that bring some of
|
||||
the power of a UNIX system to the Apple IIgs. Also, a number of
|
||||
programming libraries are included that make it easy to port
|
||||
programs from UNIX or MS-DOS systems to the Apple IIgs.</font></p>

<p><font face="Times">GNO/ME is a very large system. Most of the
|

system is stored on the three disks in a compressed format. For
|
||||
this reason we recommend that you read this section carefully and
|
||||
use the included automated installation program to save yourself
|
||||
the major headache of arranging everything. You'll need a hard
|

drive partition with at least 5 Megabytes free to install GNO/ME.
|

The entire installation process should take no longer than 10
|
||||
minutes. </font></p>
|

|

<p><font face="Times">If you are upgrading from GNO 1.0 to GNO
|
||||
2.0, we recommend that you install GNO 2.0 on a new area of your
|
||||
hard drive. This is because GNO 2.0 provides new versions of
|
||||
almost all the utilities and other software provided with GNO
|
||||
1.0. You can then move the parts of your old system that aren't a
|
||||
part of the standard GNO 2.0 distribution over to the new
|
||||
installation. </font></p>
|
||||
|

<p><font face="Times">The installer program is able to the copy

the GNO libraries for use with the ORCA languages and tools. If

you want to use your ORCA languages and tools, you should answer
|

the appropriate questions during the install process. ORCA
|

installation is covered in more detail below.</font></p>

Install are boldfaced in the following discussion. If

"ORCA" on one of your hard drive partitions. On

our system, it is :software:orca. The location of this

file determines where Install puts the GNO-specific
|

ORCA/C header files and libraries (in the ORCA LIBRARIES

directory). If you have renamed ORCA.SYS16 to something
|

else, select that instead. </font></p>

<p><font size="2" face="Geneva,Arial">Install uses this

information to correctly set the ORCA prefixes and add

the EXECUTABLES directory to the $PATH variable in your

accessories that are shipped with GNO/ME.</font></p>
|

<p><font face="Times"><b>GSI NDA</b></font></p>
|
||||
|
||||
<p><font face="Times">The Graphical Shell Interface New Desk
|
||||
Accessory allows you to access the shell from a window inside a
|
||||
desktop application. Selecting 'GSI' from the Apple menu opens a
|
||||
window and brings up a shell in it. You can use the shell in this
|
||||
window just as you would in text mode.</font></p>
|
||||
|
||||
<p><font face="Times">At this time, GSI doesn't support any
|
||||
terminal emulations; i.e., it's a 'dumb' interface. As a result,
|
||||
full screen programs like 'less' and 'vi' will not work properly
|
||||
in GSI.</font></p>
|
||||
|
||||
<p><font face="Times"><b>Suspend NDA</b></font></p>
|
||||
|
||||
<p><font face="Times">The Suspend New Desk Accessory allows you
|
||||
to temporarily stop a desktop program and return to the text
|
||||
shell. To return to the desktop program, simply type '<b>fg</b>'.</font></p>
|
||||
|
||||
<p><font face="Times">You may put desktop programs in the
|
||||
background ('<b>bg</b>') at your own risk. This is not guaranteed
|
||||
to work for all programs, and putting a desktop program in the
|
||||
background will not put the Apple IIgs in text mode.</font></p>
|
||||
|
||||
<p><font face="Times">Also, do not run another desktop program
|
||||
when one is currently suspended. The GNO kernel tries to cleanly
|
||||
terminate the second program, but may not always be able to
|
||||
accomplish this.</font></p>

||||
|
||||
<p><font face="Times"><b>GNO Snooper CDA</b></font></p>
|
||||
|
||||
<p><font face="Times">The GNO Snooper CDA is a utility that is
|
||||
very helpful in debugging software, and reporting system crashes.
|
||||
Snooper has access to information inside the kernel that is not
|
||||
generally available to processes.</font></p>
|
||||
|
||||
<p><font face="Times">When you enter the control panel and choose
|
||||
"GNO Snooper" a process list is displayed, which is

<p><font face="Times">D)etails</font></p>
|
||||
|
||||
<p><font face="Times">Get detailed information on a process.
|

Snooper asks you for the process ID number of the process you

want to investigate. Snooper then dumps the state of the 65816
|

registers and shows various other information about the process.</font></p>

<p><font face="Times">K)ill</font></p>

<p><font face="Times">P)rocess Group Dump</font></p>
|
||||
|
||||
<p><font face="Times">Dumps the system process group tables,
|
||||
which is very useful for debugging code which manipulates process
|
||||
groups. The first table, 'pgrp', is the process group reference
|
||||
count table. This table lists how many processes (and TTYs)
|
||||
belong to that process group. pgrp ID's start at 2, so the first
|
||||
pgrp listed is 2.</font></p>
|
||||
|
||||
<p><font face="Times">The second listing is the ttyStruct table.
|
||||
This table shows which pgrp each TTY belongs to. The TTYs start
|
||||
with .null (0), then move on to .ttyb, .ttya, .ttyco, etc.</font></p>
|
||||
|
||||
<p><font face="Times">F)ile Table Dump</font></p>
|
||||
|
||||
<p><font face="Times">Lists all open files that GNO knows about.
|
||||
The information is presented in tuples. The first element is the
|
||||
real GS/OS refNum or device driver ID. The second is the type of
|
||||
file (GSOS, ttyXX, or PIPE). The third is how many references to
|
||||
that file are open. This information is global, so if two
|
||||
processes have .NULL opened, the refcount for .tty00 will be 2.</font></p>
