Very silly. awk + tr + cut is highly redundant and bc is not installed on
my system. :)
Here's something simpler that produces the same output for a single
processor without bc...:
$ grep bogomips /proc/cpuinfo | sed 's/[^0-9.]*//'
... although my system only says 729.08 :)
> Your mission: To work out what it's doing, why you'd be stupid enough to

> has to handle decimals! :-)
Given that bc or dc are not guaranteed to be installed, I use expr
instead, but doing decimal calculations involves fixed-point maths.
all that given, the following works properly on a multi-cpu system:
$ expr 0 `sed -e 's/[0-9][0-9.]*/&000/' -e
's/^bogomips[^0-9.]*\([0-9]*\)\(.\([0-9][0-9][0-9]\)\)*.*/+ \1\3/' -e
'/^[^+]*$/d' /proc/cpuinfo` | sed 's/[0-9][0-9][0-9]$/.&/'
... be careful of the back-ticks and single quotes. I tend to use single
quotes to give my sed scripts better protection from the shell. the $ is
guaranteed not to be misinterpreted that way.
Ok, it's nasty, but it does it in 3 processes and with shell utilities
that will always be available.
Basically, Sed appends extra zeroes to all numbers, converts bogomips line
to a plus sign and a fixed three decimal places, and throws away the rest.
I then use expr to add the bogomips values to zero and put the decimal
point back in with a second sed.
now to why?:
To tell the user how long something's going to take, of course! :)
It's a slackware tradition to estimate how long something is going to take
in BogomipSeconds... the number never changes, but as you get more
Bogomips, you end up with less seconds. This chunk would give the shell
script a way of turning that abstract number into a time that an ordinary
user will understand. :)
Do I get the prize? :)

Answer: It does, but under linux's filesystems a certain percentage of the filesystem is reserved for root, so things like a full filesystem can be recovered from comfortably. You won't see any change in the percentage used until you remove at least enough files to make up for that reserved space.

To replicate the behaviour you are expecting, you will need to replicate the shell's behaviour in finding the executable. First see if it's an absolute pathname and check if it exists, then try each of the pieces of the PATH environment variable until you find the directory it exists in. I assume you have a good reason for needing this. just about everything else sets up filesystem locations for data files, etc at compile-time... not just because it's marginally easier, but because it's a lot cleaner and more predictable.

I still can't figure out what process is holding the mailboxes. Check the ownership and permissions on /tmp, /var/spool/mail, and the mailboxes in /var/spool/mail/ The diretories should have permisions like drwxrwxrwt and the mailboxes should be writable by the user and owned by the person they belong to.

The filesystem is smaller than the partition? This could happen if mkfs wrongly detected the partition size. I've not seen this happen except when I've had cause to do raw copies of partitions, but you can check this by doing: dumpe2fs /dev/sda3 | grep 'Block.*:' (the last part so it doesn't fill your screen) Multiply 'Block count' by 'Block size' and compare this with your figures above. If it's the same as what df is reporting, then your filesystem isn't using the whole partition, and you should probably back up and recreate it, probably giving the real size to mkfs.

No. Because there's less overall. When you compile a kernel, all the options take up space in the kernel, and the image that gets loaded at boottime is bigger with more options. Some of the space isn't needed after the machine has booted, though. Stuff like hardware initialisation and kernel arg processing only happens once, so the memory used by them is made available to other things. Because you're compiling a kernel with less options, there is less wasted space in the first place. That's why the number gets smaller. :) -- Jessica Mayo.

On the subject of compiling drivers into the kernel, I'd like to contrast
with MS Windows at this point:
Under Linux, it's normal to compile the kernel only with the functionality
you require at boot time, and load other drivers as modules later.
You usually need harddisk, filesystem, and a couple of other drivers at
this point.
MS Windows is no different. The difference lies in the simple fact that
windows only supports (at most) two filesystems at boot time, and that it
boots in real mode, using the BIOS for IDE access, which is much less
efficient.
> Longer term what should the linux community do to make the production of

I don't believe Linux is that bad in this respect. The problem is when the
people writing drivers don't have access to proper harware documentation.
I have read a report from someone doing commercial driver development
under contract that Linux is an ideal platform to develop drivers for
porting to other OSs, eg MS Windows.

You sound like you'd be interested in what's happening with the Uniform
Driver Interface (UDI), aimed at allowing manufacturers with these hangups
to write a single driver that can be run on multiple operating systems.
http://www.projectudi.org/specs.html

Text document? HTML document? Even on MS Windows, the standard README
files are still just plain text. :)

Provided you (or your distribution) compile the kernel correctly, you can
already use driver modules on any distribution with a compatible kernel
version. This is nothing new, and few manufacturers do actually supply
closed-source drivers in this manner.

The .inf is not a compiled DLL, and completely seperate from what it's
installing. :)
Linux has it's (various) equivelents: .deb .rpm and the oldfashioned .tgz
(these in decreasing levels of complexity and fuctionality :)
Both .deb and .rpm offer SIGNIFCANTLY better functionality than .inf
files, and are used extensively for applications, whereas .inf files are
normally reserved for the relatively simple requirements of device
drivers, and custom executables used for installing applications. (ugh!)
In practical terms, I have not yet seen linux drivers packaged seperately
in any format. The advantage of this would be to configure it as it's
installed, but the usual aproach is to install them all at once and leave
the configuration until later.

The problem here is twofold:
1) for many manufacturers, ANY aditional effort is too much effort.
They are used to writing windows drivers, and they'll keep doing so.
2) As you alluded to at the top of your email, the Linux driver interface
does not seem as stable as the windows one. Some drivers are indeed
incompatible between W95,W98,etc but that number is very small.
Linux drivers became incompatible more than a couple of times within
the 2.2 series kernels, hence the preference for open-source drivers.

Suggestion: Redhat 6 doesn't seem to load the parallel port drivers by default. do 'modprobe lp' as root, then restart the printer daemon. If a whole lot of stuff starts printing (all those spooled files) Then add that command to your /etc/rc.d/rc.local 'lsmod' lists the currently loaded driver modules. I think that parport_pc will not be in that list. As always if you need to run something as root: If you're not familiar with modules or modprobe, then read up on them before running the command.

[SLUG] I dream in #!/bin/bash (splitting a diff patch)
I was looking at UML this morning. I wanted a Win32 port.
I downloaded the patch to the latest stable 2.4 kernel.

But I'll never get started with distractions like these...
... I wanted to look at said patch file in a non-linear fashion. :)
It contains diffs for a large number of files in the kernel tree, and I
wanted an overall picture, not the line-by-line view I was getting.
I wanted to extract those diffs into their proper tree, without patching.
... enter grep.
I could grep for all lines containing 'diff'. That would show me all
modified/added files, but looking up more detail was still tedious.
... enter a monster... :)
cat uml-patch-2_4_18-10 | {
while read LINE; do
set -- $LINE
if [ "$1" = "diff" ]; then
echo
while [ "$2" ]; do shift; done
FILE="$1.diff"
if [ -e $FILE ]; then
echo skipping $FILE
FILE=
else
echo creating $FILE
mkdirhier `dirname $FILE`
fi

echo -n .
[ "$FILE" ] && echo "$LINE" >> $FILE
done
}
... enter bright idea
. o O (Maybe someone else wants to do this)
. o O (If I post it to slug, it'll pop up in the archive search...)
... footnote
I used set/shift to set the args and pick out the first/last words so bash
didn't have to spawn a subprocess. I normally would've used 'cut', but
doing it for every line slowed things down a lot.

This was probably a waste of bandwidth.
There's probably a proper tool somewhere to do the job.

I recall trying this with smbmount recently and it appearing to have no effect... filesystem still mounted root:root... I can't guarantee what samba/kernel version it was on though.

if [ `eval echo $"${i}exportflag"` == "yes" ] ; then
...
But that's a nasty piece of code.
I really would suggest putting the export flags somewhere other than in
the same file as the script. Even have a seperate file just listing the
companies to export.

I can find nowhere in IRM that this is set. HOSTNAME+DOMAINNAME = Fully Qualified Host Name vortex + vortex.olmc.nsw.edu.au = vortex.vortex.olmc.nsw.edu.au should it really be this: ? HOSTNAME+DOMAINNAME = Fully Qualified Host Name vortex + olmc.nsw.edu.au= vortex.olmc.nsw.edu.au i.e. it sounds like your domain name is misconfigured.

This is going to sound really daft... The best way to ensure your keypress packets don't get split is to wait for the result of each kepress to appear on the screen before pressing the next key... Thus forcing the client to send lots of little packets that won't get split, rather than delaying a moment and then sending several keypresses at once. > The problem is that at the receiving end there could be a timing problem where > if the string gets split over more than, say, 10 msec then it not considered to > be the result of just one keypress, but is considered to be the result of a > number of individual key presses and thus gets handled differently. Yeah, there's piles of laments about daft design of dumb terminals all through the ncurses documentation. Whoever decided to use escape codes and then put an escape key on the keyboard must have been daydreaming. I guess you could find a way to just assume that escape won't occur on it's own... but that's just as bad an option, in my book. Users expect it to do something. _I_ should probably do a search, but it's not my promlem. :) I'll just wait to hear how you do. :) -- Jessica Mayo.

Many restaurants have the same soft drink equipment that take-away chains have - it comes out of a tap, and there is no can to be had. Sometimes they do also have cans available for takeaway customers, but you would have to specifically ask for it... re: water... I have found that there are increasingly few places in sydney that will provide tap water. This accelerated dramatically at the time of the crypto-spiridium and ghiardia scares. Can you assure me that what you served was indeed tap water? The problem is that restaurants have no assurance over the quality of what they are serving. If you get sick from drinking the water they server, you won't think much of the restaurant, will you? > This i feel is shocking service, we as a group spen more then $800 there > and they give us this shocking service. I think that SLUG should > re-asses its dinner arrangments if this is the kind of service that we > recive. I do agree that the service is indifferent, and the waiters hard to attract for drinks, but apart from that, the complaints here would apply equally to any fast-food chain. The House of Guang Zhou is ionly one step above KFC. Do you have an alternate suggestion? I'd happily hear it. :) > Paul. -- Jessica Mayo.
