BIOS may SEE it properly but it may not REPORT it correctly to the
kernel. Sometimes a big deal, sometimes not. Sometimes it really
sees the full amount of RAM.

I don't know if this is an Oracle, Java, or Linux question....Oracle's
documentation for 8.1.6 for linux says it supports Java 2, which I thought
was Java 1.2 and higher. But the doc also says that 8.1.6 ships with
version Java 1.1.8. Is this a Java 2 platform?
Please help me with my confusion.

Ok you do this and get the output
'Sep 13'
Now try it without the single quotes.

So it's leaving the single quotes in,
I've taken the single quotes out of the first line and
I've put double quotes round $todaysdate because grep
sees that as a string not a variable, the shell expands
that variable which produces two strings (or something like
that.
This works:
#!/bin/bash
set $(date) ; todaysdate="$2 $3" ; \
grep "$todaysdate" /var/log/messages
You'll probably have to run it as root or give yourself
read access to all the files in /var/log/messages.

Have a look at the security information in the apache docs, also the

Thanks. It does everything I needed, except I just found out the image
can't be bigger than 150 pixels. :-(
Any chance you'd know of a utility to chop-up an image file into smaller

I assume you are going to the exact same PostgreSQL version. If you copied
the data/base/* directory trees only, you missed some files inside data/
which it needs, like where it keeps the list of databases. But you might be
able to recover by using createdb to create a new empty database with the
same name, then replace data/base/'name' with the 'name' tree from the
other system. If it works, I would then do a full dump and restore into a
new database just to be safe.

No, Java 1.1.8 is not Java 2.
Oracle simply states that 8.1.6 will work with Java 2 (i.e. they don't use
Java 2 specific features yet).
Hope this helps.

Two ways:
todaysdate=`date +'%b %e'`
grep "$todaysdate" /var/log/messages
And
todaysdate=$(date +'%b %e')
grep "$todaysdate" /var/log/messages
Just two ways of doing exactly the same thing.
Here are the same two methods, but skipping use of the variable:
grep "`date +'%b %e'`" /var/log/messages
grep "$(date +'%b %e')" /var/log/messages

This is the original problem, with new arguments. The shell
looks at your grep command line, and expands the variable
_$todaysdate_, which results in two tokens being passed, one of
them is _'Sep_ and the other is _12'_. The first one grep takes
as a string to search for, and the second one it thinks is a file
to search in. Hence the error message about no file named _12'_.
If _$todaysdate_ is put inside single quotes, the shell will not
expand _$todaysdate_ and will send exactly that to the program.
Clearly not what you want! If _$todaysdate_ is put inside double
quotes, the shell will expand _$todaysdate_ and pass the results
as a single argument to the program, which is what you do want.
And, obviously what you have been doing, which is no quotes,
causes the shell to expand _$todaysdate_ and pass each token as
an argument to the program.

Subject: Corel Linux won't boot!? Hangs indefinitely at startup
Date: Wed, 13 Sep 2000 01:28:40 GMT
I am desperate! Help save the Pentium 90! *heh heh*
I am trying to revive an old windoze system for my school (in the graphics
lab- which is mostly Apple G3's) This old computer was on the way to the
dump, and I came up with the brilliant idea of installing Corel Linux on
it, as to have students use the system to view webpages on, or even do some
work in Gimp, or other apps in the Linux format.
Let me start by saying that I am a MAC & Windows guy, and am totally new to
Linux terms. Forgive me in advance.
The computer is a Pentium 90, with 80 MB RAM, and a 720 Gig HD. I knew I
could install Corel Linux on it because I have done so on my P120/22MB RAM
at home.
The install was very fast, and the system boots in very little time, but it
hangs at the black screen directly before the menu where you choose root
user, or other users. (I know this because Corel Linux works on my P120 at
home)
I have already tried a reinstall with no better luck.
Any help would be extremely...... helpful?

Thanks, but that part's fine. I probably didn't express myself properly.
:-)
I've resized it and rotated it the way I need. The problem is that the
image can't be more than 150 pixels high or wide, BUT my image is longer
than 150 pixels. For example, say it's 150x400. I need to keep that 150
pixel width, so I need to chop-up the image in 3 pieces of 150x150,
150x150, and 150x100.
When I write my HTML code, I can stick the 3 images next to each other and
form a complete picture again.
In case anyone's wondering, this is for an Avantgo site which will display
on a Palm computer. The Avantgo software is limited to 150 pixel images,
thus the kludge necessary above...
Thanks,
js.
