There is also a little trick: Notepad doesn't understand the UNIX files, but the
old DOS 'edit' does!
So just open them in DOS 'edit' and save them. Or use some of the convert progs:
duconv, unix2dos, dos2unix...

This is really getting close to what the origional post was all about! Only
it is isn't what is in the document that I want to know, but the information
that is typically "encrypted" into the installation program! I want to know
what files, directories, configuration settings, etc. that a program relies
on in order to be operational. I know this information is in the install
program the developer provided. Thus I often uninstall and reinstall the
program to try to fix the program (success rate: 20 percent).
The problem is that every software component is handed to me in the same,
encrypted format (a pile of installs from various venders). No meta
information about how these structures are supposed to be interrelated. No
single and separate "installation" facility (or what I would call a
"Software Rendering Facility") for collecting and tracking this information.
Perhaps the developer doesn't WANT me to know what they are going to do to
my computer's storage in order to install their program. Well, in that
case, I don't want their product. I am sick and tired of having a dead
machine because some stinking DLL or registry setting is screwed up, and I
haven't got any reasonable way of figuring it out. In fact, I have such a
laptop (a four week old, top of the line Dell with a dead Windows 98)
sitting right over there in the corner.
My point is we have gotten past the idea that the writer is responsible for
laying out each page in a document. Let's get over the idea that each
developer has the responsibility for laying out my storage.
There is little to hide when it comes to how to install software. So why
don't developers just lay out what they need done in plain English (or
swahili whatever) already!

Thanks very much for the pointer.
Actually what I get is
/usr/share/doc/HTML/de/kppp/hayes.html
/usr/share/doc/HTML/en/kppp/hayes.html
/usr/share/doc/HTML/en/kpppload/gpl.html
/usr/share/doc/HTML/en/kpppload/index.html
But I'll see if I can find anything there.
I must admit that I'm completely baffled
by the KDE attitude to documentation.
It seems that a huge effort is going into this --
yet the simplest things,
like leaving the documentation in the normal place,
seem to be ignored.
I'm probably rather old fashioned,
but I think there is a lot to be said
for a 1 page man-page,
if only to point at other documentation.
I should say that I am (probably foolishly)
running KDE-1.92 under pinstripe.

There's no reason why linux shouldn't mimic this though.
Linux does have Ramdisk capabilities, after all...

Let me get this straight. I have posted a fairly long document that claims
that installation of software is nothing more than properly rendering
storage. I also claim that this can be done automatically by a third party
so long as the developer exposes enough information (i.e. what must exist in
storage in terms of files, directories, and configuration settings) for a
third party to construct such a rendering. Assuming we can do that, I go on
to lay out the associated benefits of the approach.
It would seem that you believe file system defining a computer system's
configuration is something more than just another structured data format.
It must be magic, then?
I am not the one that believes in Witchcraft.

To be exact, the DOS conventional newline consists of ASCII-chars 0x0D 0x0A
(or 13 10) that's ordinarily represented by '\r\n'.
> MacOS uses '\r'.
Since what '\n' exactly is is subject to local conventions, MacOS uses
'\n' too, but '\n' on MacOS is ASCII-10 that happens to be '\r' on most
other ASCII-based systems. (This can be confusing, especially when writing
network protocols or file formats that are supposed to be OS-independent.)
ASCII defines 0x0D as CR (Carriage Return) and 0x0A LF (Line Feed).
Historically, typewriters, teletypes and then printers required separate
commands to return carriage to the left end of paper and to scroll the
main roll even though they're intuitively a single operation. Since it's
much easier to handle newline as a single char than if it'd be a token
of multiple chars, it's been modified by different systems for simplification
purposes but different systems have done it in different ways and thusly
created incompatibilities.

Some consider Perl a shell scripting language of sorts. If you use
Perl you can open a file and operate on it line by line, or character by
character, or whatever. You can also forget sed and grep, and use the
Perl functionality. THIS is the way that I would go.
Already the $$ has been pointed out, so no need to rehash that.
You can try some clever combinations of "cat" and "|" and ">" to read
the file and write back out to it: e.g.
cat bob.txt | sort -r > bob.txt
mtc

==============84E77F54B2407219CE97F698
Content-Type: text/plain; charset=us-ascii

Dear Everyone,
I have sucessfully set up a DHCP server between Liux systems with the
eventual intention of also networking a windoze system with samba and a
mac all on the same network.
I chose DHCP because I found a really good book by coriolis (Setting up
a Linux Intranet Srver , www.coriolis.com) which explains how to do
this.
The only problem is that this wonderful book doesn't explain how you
should interface 2 systems together running linux.
I understand I have 2 possibilities:
1. Use NFS
2. Use smbfs, seeing as I already have to set up samba to interface the
mac and the windows system on the network anyway.
I have 2 questions:-
1. Should I use NFS to communicate between linux systems ?
If so, how do I install NFS on my redhat 6.1 linux box and set it up as
a client under dhcp ?
2. Is it possible to use samba to run file transfers between my linux
boxes ?
Is this preferrable in terms of security considerations to running NFS ?
Also , How do I install samba on a linux 6.1 redhat system as a client
under a dhcp protocol ?

I don't think you're quite right here.
Some people do consider Perl to be a scripting language, but I don't
think I've ever heard anyone call it a _shell_ scripting language before
now. Many discussions go on regularly about whether it is a scripting
language or a programming language, and people get in knots trying to
find out what the difference betweenthose two is. However, a shell is a
shell, and perl ain't one of those.
Maybe you know another 'some' than I do, and in that case you are right,
but they are still wrong.

Perl is a good language for many system administration tasks, and often
you'll find that shell scripts that use a lot of sed, grep and awk will
benefit considerably from a rewrite in Perl. However, don't make the
mistake of using Perl when you need to call large numbers of external
programs. While perl can easily do tat, shells are normally better at
it.
Some things work well in shells, some in Perl, and some in C. I believe
that that was more or less your point as well, but I couldn't just let
you call Perl a shell scripting language, now, could I? :)
