Thanks,
You're welcome. A very minor contribution back to the community.

Youl need to change this to suit as hdc is probably most used for the
first hard disk on the first IDE channel of most default systems.
Yeah, there's a note in the comments within the script that this needs to be
set for whatever drive your burner is. That's what mine is, just because it's
the first device on the second ide bus.
If anyone knows a way to make this more generic, I'd be happy to apply the
change.
/usr/bin/growisofs -Z ${DVDDEV}=${1} \
-use-the-force-luke=notray -use-the-force-luke=tty \
-use-the-force-luke=tracksize:2268160 \
-use-the-force-luke=dao:2268160 \
-dvd-compat -speed=4
2268160 = this is the real tracksize in bytes, so this would need to be
altered for each burn.
Yeah, I was curious about those numbers, since the options are undocumented
(at least in the man page). I thought they might need to change for each disk
image. But I burnt three different images each of a different size, and they
all seemed to work. So it's not clear to me when these numbers would need to
change.

I didn't notice this link previously. Sometimes I don't get a chance to read
my email for a couple of days, then have to very quickly scan several hundred
messages, so I probably scanned right over it. I'll check it out.
I added another line to the script, making it version 0.2:
eject ${DVDDEV}
This makes it eject the disk when burning is done, providing a convenient
feedback that it's done, similar to K3b (though this seems to be broken for
DVDs in K3b; it only works for me with CDs).
Thanks for the feedback.

[newbie] Script for burning DVD images
I ran into an interesting problem today. I have some wedding DVDs that family friends keep asking for copies of. I had been using K3b's Copy DVD tool. But I realized I could shave about 20 minutes off the time for each disk if I saved the image and reused it, instead of rereading the originals each time. I saved the images by selecting the Only create image option. But when I went to burn copies, I ran into trouble. I had assumed that K3b would create an ISO image, and that I could just do a Burn DVD Image from it. I was worried when I saw the .img file extension that K3b used, rather than the conventional .iso. I tried anyway, but the disk was unusable. Then I tried New Data DVD Project, added the image file, but same result. I couldn't find anything in the K3b help, or on google. So I went back to copying from the original. But after a successful copy, I was able to grab the actual command executed to burn the image from the Debugging Output of K3b (I wish all GUI tools would give you the command line equivalent like this, very educational). Turns out it's the growisofs command, with a number of undocumented -use-the-force-luke options. Anyway, I took a few minutes and turned it into a reusable script. I've attached it here for anyone who might find themselves in a similar situation. Maybe someday this missing feature will get added to K3b.

[newbie] newbie script help
Greetings and Happy NewYear,
I would like to write a script to accomplish a task, and then run it at
regular
intervals (I'll start another thread for that). The thing is I know zero
about
programming and in process of learning.
I have a stand-alone firewall (mdk9.1) with no X installed, and a wireless
card and my access to the internet is from a access point else where.
I would like to get the info from /proc/net/wireless (on the firewall)
like below.
~$ date cat /proc/net/wireless
So after a while I came up with something like this below
#! /bin/bash
#Take wireless link readings from /proc/net/wireless and output to
#file wireless_stat
{ date; cat /proc/net/wireless; } wireless_stat
--
That seems to give me what I want and I like to set it up to run every 5
minutes with cron.hourly (next thread).
Now every 24 hours I would like to take the file wireless_stat and
tar/gzip it
up and start a new one like below.
~$ tar -c -z -f wireless_stat1.tar wireless_stat
then run
~$ rm -f wireless_stat; touch wireless_stat;
How would I write a script that it would increment the the archived files
like logrotate does? For instance.
~/tmp$ ll
-rw-rw-r--1 mike mike 3084 Jan 4 08:44 wireless_stat
-rw-rw-r--1 mike mike 359 Jan 3 19:33 wireless_stat1.tar
Then 24 hours later this.
~/tmp$ ll
-rw-rw-r--1 mike mike 3084 Jan 4 08:44 wireless_stat
-rw-rw-r--1 mike mike 359 Jan 3 19:33 wireless_stat1.tar
-rw-rw-r--1 mike mike 359 Jan 3 19:33 wireless_stat2.tar
This where I'm getting stuck would this be a loop? or a statement?
Would it be a (if, while, for,)? I have a book to help, but I'm afraid
my brain is stuck in a (loop) of not understanding and can not
progress... :-)
Any guidance would appreciated,
Mike

Re: [newbie] newbie script help
Hi Mike,
Your script to 'logrotate' the files could look like this:
#!/bin/sh
filetest()
{
if [ -f wireless_stat$1.tar ] ; then
mv -f wireless_stat$1.tar wireless_stat$2.tar
fi
}
cd /directory where your files are
filetest 4 5
filetest 3 4
filetest 2 3
filetest 1 2
The filetest function takes 2 arguments, being the oldest and one newer
file (you can expand this check to as many as you like, but if you want
to keep things around forever, this would not be the best way to do it).
To run this thing, put it somewhere and let root's cron take care of things.
Paul

Thanks Paul!
I think I understand the function is to take the oldest which is the
first argument
if it exists rename it to the second argument. So it cd's to my file
directory and
sees if wireless_stat3.tar it would filetest 3 4 (rename file3.tar to
file4.tar) and
2 to 3, 1 to 2. Yes, I was wondering how to keep it from running
forever. I see
now by what you have in your script.
Now to put it all together could I do something like this?
-
#! /bin/bash
tar -c -z -f wireless_stat1.tar wireless_stat
something()
{
if [ -f wireless_stat1.tar ] ; then
rm -f wireless_stat; touch wireless_stat;
fi
}
filetest()
{
if [ -f wireless_stat$1.tar ] ; then
mv -f wireless_stat$1.tar wireless_stat$2.tar
fi
}
cd /home/mike/tmp
filetest 4 5
filetest 3 4
filetest 2 3
filetest 1 2

Yup.

Good! :)
Now to put it all together could I do something like this?
I'd suggest this:
#--start script
#! /bin/bash
filetest()
{
if [ -f wireless_stat$1.tar ] ; then
mv -f wireless_stat$1.tar wireless_stat$2.tar
fi
}
cd /home/mike/tmp
filetest 4 5
filetest 3 4
filetest 2 3
filetest 1 2
tar -c -z -f wireless_stat1.tar wireless_stat
if [ -f wireless_stat1.tar ] ; then
rm -f wireless_stat; touch wireless_stat;
fi
#--end script
First you define the function (it is only defined, not run), then you cd
to $HOME/tmp. Then cycle the backup tar-files. That way you move the
existing backups out of the way, preserving the old #1 as #2 and getting
rid of old #5 in the process. And then you build the new stat1.tar after
which you create a clean stat-file. Do you see the logic in this?
I hope this is clear enough.
Good luck,
Paul

I believe I do now, I had things reversed, I should of taking care of
moving my backups
to make room for the new ones before deleting the first file, else lose
data!
Also I noticed that I was trying to make a function out a if statement (
something() )
which was not necessary, probably not right either *grin*
And the #--startscript, #--endsript to know when the script begins and ends.
I should also add some comments about what its doing for my sake.
I hope this is clear enough.
Yes, again thanks Paul!
You walked me right through it, easier than I thought it would be.
I'll probably post back on the running the cron part but, I'll research
it a bit more before I panic. :-)

Re: [newbie] script help
Here's the rub, by type ./HW you are telling bash to run it in the current directory. Also, path's are NOT recursive, so when you put it inside a second folder inside the ~/bin directory, it will not see it. Put the HW script directly into your ~/bin directory, then then type just HW (NOT ./HW) Chuck On Wed, 2003-01-01 at 17:10, MG wrote: Hey Mark, I was just using ./HW as in: [mike@avatar mike]$ ./HW What I gathered was if the script was in a directory, that was in my PATH, I could just use the name of the script instead of the whole path.

Re: [newbie] Script errors during kernel upgrade
I don't think you can regenerate that file. It is not necessary for the stock kernels to boot and is just something Mandrake put it in there. Try creating just an empty file with the name the rpm wants. module-info should be a link to module-infokernel version just like vmlinuz was a link to vmlinuzkernel version.
