I have to admit that I register to LQ after I failed to search for similar solutions.let me see whether I can explain my problem clearly. I need to extract a single report from a big file. The big file looks something like this:
Report for yyyyyy
Your info 999-9999999
End of Report
[code]....
I need to search for a user provided string, say 999-9999999, in the big file. Then I have to extract the single report. My logic is simple,
1) find 999-9999999
2) backward search for "Report for", note down the line number
3) forward search for "End of Report", note down the line number
4) extract the record by using info found from step 2) and 3).
I am trying to do this in bash, with awk and sed (I am new to both).
I am in need to create a script that queries how large a partition is and when it hits a certain percentage (say 90%) it will execute another script that tars up certain files (or they could just be part of the same script). I would create a cronjob that runs this script once a day.
I have the script that tars up the files I need, sets permissions, etc. (btw, the files in question are audit logs). I just need the part that runs something like a df -h and takes the use percentage of the /var partition in that query and if that percentage is greater than/ equal to 90%, it kicks off the tar script.
Here is a sniplet of the df -h with just the /var partition shown:

So, when the cronjob sees that the Use% is >= 90%, it would kick off the tar script...if not above 90%, it closes.
I have ASCII files to parse that 48 hours old or more ; I can identify them like so
Code:
find . -name "FILE*TXT" -mtime +1 -exec ls -ltas '{}' ';'
Some files have a list of hardware errors (we test electronic components), some have none. If the file name has no errors, I still want to display a message like so
Code:
grep ^err R*VER && echo "No error"
FILEA.TXT:err->USB3910err
FILED.TXT:err No Error
This grep statement works but it seemingly overrides the find() statement above if I run both at the same time... How can I combine the two statements to create a report that lists the filename and error(s) like so
Code:
FILEA.TXT Button3320err
FILEB.TXT USB3235err
FILEC.TXT IR Remote2436err
FILED.TXT No error
Is it possible to return "No error" with the file name without error?

View 3 Replies View RelatedI have upgraded my machine to Karmic, and thereby getting gcc/g++ 4.4 in the process. I have some code that requires gcc/g++ 4.3.
I can change the compiler system wide by redirecting the symbolic link from 4.4 to 4.3
Code:
sudo rm /usr/bin/gcc
sudo ln -s /usr/bin/gcc-4.3 /usr/bin/gcc
but i would like to have it done per session instead.
I have a slave node uploading all kinds of backups to my server in the internet. Now I would like to display the actual upload and download rate to this server (not the entire nic-traffic, any protocol) in a small php-page for easy monitoring.I had a look at quite some monitoring tools and the one which kind of offers what I am looking for is iftop with a filter on the IP of my server. As I would like to periodically update a file with the actual rates, an interactive program won't do. A possibility would be to filter the packages myself using but this seems to be quite a long shot.The optimal solution would be a program or script printing out the actual upload to a host specified in the options to STDOUT

View 3 Replies View RelatedI want to write a single shell script that allows me to, once executed from a panel launcher, change the image preview setting between "local files only" and never. Right now i have two tiny scripts, one for local files only and another one for never, that is:
[Code]...
and the other says string "local_only". But that means i need to have two launchers, because i don't know how to write the condition <<when set to never, change it to local only. And is it possible to make a script that also changes the launcher's icon when the preview config is set to one or the other value? That way i'd know what it is set to just by looking at it. It would act as a diagnostic and therapeutic tool XD

My script looks really crap and messy, the logic isn't great and I'm not hugely happy with it. Also it echo's $i instead of an actual IP address (line 10). How to improve this. It basically searches through /var/log/messages for multiple FTP hits and when the hit count is higher than a specific number the IP is added to a config file and ftp is restarted. There are some obvious flaws in my script.
Code:
MAXHITS=0
TOPHITS=`grep "FTP session closed." /var/log/messages* | awk '{print $7}' | sed -e 's/^.*[//' -e 's/].*$//' | uniq -c | sort -nr`
HITNUMB=`echo $TOPHITS | awk '{print $1}'`
IPHIT=`echo $TOPHITS | awk '{print$2}'`
HIGHIP=`echo $TOPHITS | grep $HITNUMB | grep $IPHIT | awk '{print $2}'`
if [ $HITNUMB -gt $MAXHITS ]; then
for i in $HIGHIP;
do
echo $i
sed -i '78s/$/,$i/' /opt/etc/proftpd.conf
/root/ftp restart
done
else
echo "not greater than $MAXHITS"
fi
I'm not even sure what will happen if I get multiple responses for my $TOPHITS. It would be cool if it could search for IP's already blacklisted somehow, it might actually be easier to just create a file with a set of blacklisted IP's or something.
I need something to make a script that will search some logs and extract IP hits from one country only. Let's say UK. I guess I need to use GeoIP or some database. I just need a very simple bash, perl, php script that will do this job. Just search threw logs (apache) and then give me number of hits found from UK.
View 5 Replies View RelatedI haven't recompiled ny kernel in a while, but whenever I did it, it was all pretty easy. Make menuconfig; (adjust); make && make modules_install, and copy over bzImage in */arch/* and System.map to /boot and stick in new entry into grub menu.lst.However, this time, I must be missing something, because I get kernel panic on booting up to the new kernel. Is there a step I'm missing?Certainly, I was looking in /etc/rc.d and there is a rc.modules<kernelver> script in there. I wondered if I need make a new one ... although when I looked over it, it seem only to be required when forcing particular modules.
