what do you mean by 'finding your win98 partition' can it see any
partions on that hdd? is the hdd detected at all? if so is it on ata100
interface or pci card? if you mean that you just can't access any data
on your fat/32 partition then its a whole different problem. what are

That remains to be seen. The GUI is very glitzy, and it will get a
great deal of application support from companies like Apple and
MS. The interface in NOT X based, and it's based in a Macintosh
sensibility, if you like that sort of thing.
Right now, it's not ready for prime time. I had to spend several
nights trying to get Apache/PHP4/MySQL running on it, something that
on Linux would have taken me an hour. But to be fair, the
indications are that Apple knows that it isn't ready for masses
yet, and it is under active development. It is good enough to serve
PHP/MySQL web pages.
>Is it a kind of Unix at all?
Yes and no. It certainly has Unix underpinnings, you'd feel quite at
home with the bash command line. It doesn't feel like unix in some
of the way you configure it. You don't use /etc/hosts or
/etc/resolve.conf. It uses the netinfo app in many places where
Linux would use a nice text file.

Powerful, GUI, but not expensive. A couple hundred dollars. More
expensive than Linux or FreeBSD, but less expensive than NT, which
is what it's trying to compete with.
>
>Anybody there who have tested OS-X yet? Any opinions?
Most Linux apps won't compile out of the box. Most Mac apps don't
run perfectly. But it is stable in my hands (G3 Powerbook with 256M
RAM) and BBedit and VIM and Pepper (a native OSX programmer's
editor) run acceptably well, so it makes on OK web development box
once you get your choice of languages running there. (It comes with
Perl I think, Python has been ported IIRC, I'm using PHP4)
It's early days yet. I think it will make an impact, but on who we
have yet to see.
See you.

Subject: book recommendation?
Date: Fri, 20 Apr 2001 09:48:40 +0100
Happy newsreaders...
(You may skip to NOW THE QUESTION IS section, if you don't want to read it
all.)
I am sure everyone out there started in the same way I have, ie, making
loadsa mistakes. That's one way of learning, very harsh too, the other way
is by reading books.
I recently bought Red Hat Linux 7 Unleashed. The only useful chapters were
the first 5. Then it got to "technical" for me "whoooosh!". Oh, I also
installed Red Hat Linux from the CD that came with it. I finally went to the
shop to buy "the complete idiot's guide to Linux" which I found amazingly
interesting and useful. I read about 87% of the book!
Now I want to go deeper into Linux Administration. Perhaps one day I will be
able to answer (hence help) most of the questions asked by the newbies in
this forum.
NOW THE QUESTION IS:
Could anyone recommend me a good book that will teach me things like:
- how to modify and understand .conf files
- how to install and uninstall packages
- how to check on memory usage and needs
- how to administer other users in my system (which is composed of my wife
and myself...)
- and more...
Assumptions:
- I am still a newbie, short in Linux experience but LONG in enthusiasm and
willing to learn more about this fantastic OS.
Cheers to all.

Problem: any kind of .conf file have is own syntax and purpose,
so there is no a 'general' guide about how to handle these kind
of thing. The only solution is read the documentation of the
program that use that file.
Same thing for the packages: every application have is own
way.
> - how to check on memory usage and needs
The command free will show you the amount of memory used, for
the needs, that depend what are you doing with the machine...
in general, if you see the Swap heavily used, you need more
ram.
> - how to administer other users in my system (which is composed

For this I will recommend something in the line of O'Reilly
books, maybe not focused on Linux but 'generically' on Unix.
I read Unix System Administration and it's pretty good, covering
almost every aspect of administration of a generical Unix
system.

Hi!
Thank you for your reply!
I would not like to think that the CD quality is the reason, since I have
tried new Memorex, Sony, Imation and Maxell, both CD-R and CD-RW disks and
only done simulation writes. I used the speeds 1,2 and 4 for testing since
I thought that using 8 will just generate replies with recommendations for
using a slower writing speed. I should have mentioned this in my first
posting.
It seems that at least the newer drives are simply incompatible with my
system... I'm afraid that trying something else than LG might be the only
solution, especially because of the kernel errors. Or does anyone have an
idea what to try next?
Best regards,
Iiro

I agree that Linus might want to set up some sort of committee OF INDIVIDUALS
when he decides he wants to move on to something else.

I want to display (using tail -f) the contents of /var/log/messages in a

I added this to my initab but the ouput displays in my F1 (main)

the grep at the end is because my firewall logs TCP stuff to the messges

also, is there anyway to allow me to scroll back up the screen? ie, some
program that has scrolling that will watch a file (like tail does) and

Assuming $USERBIN points to the user directory:
as root (ksh syntax - bash2 should be similar):
cd "$USERBIN"
for file in *
do
[[ -h $file ]] && chown -h root:sys "$file"
done
chmod +t "$USERBIN"
By setting the sticky bit on the directory, only a file's user will
be allowed to delete the file. Changing the ownership on the link does
not affect it's use - that depends on the ownership and permissions
of the underlying file.
If your chown does not support the -h option, then you must rebuild
the link (again, ksh syntax):
cd $USERBIN
for file in *
do
[[ -h $file ]] && {
ll $file | IFS='>' read waste realfile
realfile=${realfile# }
ln -fs "$realfile" "$file"
}
done
chmod +t $USERBIN
