Software :: Pipeline Data Of Find Command In Array After Processing Contents

Jun 7, 2010

I am searching for a file in a specific folder using the following command and storing it in a log file

find . -maxdepth 2 -type f -name "components.xml" -print | while read obj
do
basename `dirname $obj` >> avail_list.log
done

Here I want to do the following
1. Store each entry after processing in an array variable.
2. Use this array variables as arguments to function calls.

Here my primary objective is to store the entries from 'find' command in an array. So it is ok for me if I am not creating the log file.

General :: Processing Script That Find Latest Version Of Each File

Mar 5, 2011

I want to write a script. I have the basic form working... but I would like to add some advanced features. I have a list of .zip files that have a version number in the filename (i.e. sudoku-134.zip, sudoku-176.zip, sudoku-203.zip, etc). I would like to have a script that will find the latest version of each game, and unzip it. I want the next to latest version left untouched. But anything older, I would like the unzipped folder deleted (But leave the .zip file)

Here's what I have so far:
Code:
#!/bin/bash
cd /var/www/vhosts/server.com/httpsdocs/games/$1
for file in `ls *.zip`; do
if [ -d ${file%.*} ]; then
echo
else
mkdir ${file%.*}
cd ${file%.*}
unzip ../$file > /dev/null
cd ..
echo 'date' $file >> /var/www/vhosts/games4roku.com/private/$1.log
fi
done
I can call the script with "game-unzip public" to unzip all the public games.

Here's my files:
Code:
sudoku-134.zip
sudoku-134/
sudoku-176.zip
sudoku-176/
When I add the latest version, sudoku-203.zip, I want it to unzip it to ./sudoku-203/ and rm -rf sudoku-134

Programming :: Processing A Command Line Literally (without Shell Quoting)

Does anyone know a method of being able to process the complete and literal command line passed to a shell script ? I want to have the command line parameters with ALL characters (including meta characters e.g. $ literally).

So as if there was no shell to substitute or expand parameters nor applying it quoting rules.

Software :: Recovering Data From MD Array (using Knoppix)

Jun 2, 2011

I had a major OS crash (Gentoo) maybe 2 months ago and completely neglected my system. Now I want to recover all my mirror raid data back so that I can restore the system. My plan is this:

1) copy all data so that I can have a backup
2) rebuild system with some HW upgrades

First step is to get the data out. I managed to boot with Knoppix and I have full access to my ext2 partitions. My mistake was to create the mirror partitions and these are not working now. I copied my /etc/mdadm.conf into /etc/mdadm/mdadm.conf in Knoppix and then tried to start the services. This is what I got:

knoppix@Microknoppix:~$ /etc/init.d/mdadm start
knoppix@Microknoppix:~$ /etc/init.d/mdadm-raid start
Assembling MD arrays...failed (failed to load MD subsystem).

I can see the partitions:

[Code]......

These are my current ideas:

1) Can I change the filesystem type from mdraid to ext2 or ext3 safely?

2) How can I mount these raid filesystems so that I can copy my data?

Programming :: Comparing Data In Array In FORTRAN?

May 16, 2010

I have two arrays of data, called data1.dat and data2.dat. each contains 60 data. What I want to do is to compare the data in each file and write the counting into bins. It goes like this. First, take the first data in data1.dat file and compare with the 60 data in data2.dat file. If there is any data which is same with the data in data1.dat then it count in bin. The total bins are also 60. Next it goes to the second data in data1.dat and compare with all the 60 data in data2.dat. If there is any data same then it add in second bin. And it repeats to all the data in data1.dat

Programming :: Reading A File Of Data In An Array?

Feb 10, 2011

I have two files of data with different numbers of columns and rows. I want to read this two files in two arrays and then compare for example the second column of first data file with the third column of the other text file and if the difference between of two numbers is less than a threshold then the program print the information in the rows which fulfill this condition in the third text file. I have written below program but the problem is that it does not go through all rows of second file.

declare -a a
declare -a b
r=` awk '{n++} END {print n}' second.txt `
echo $r
awk '
{

[Code]....

Actually I have two data files one of them contains 44406 and the other one has 12066 rows and I want to check whether the difference between the components of two specific columns is less than a threshod but I have simplified it here. I had written this code and then I have realized that this code just goes through the number of rows as the same as the first.txt file and ignores the rest. I could not find the problem yet.

Fedora :: RAID 1 - How To Create New Array Without Losing Data

Jan 1, 2010

I have a software RAID array using mdraid that consists of two 1.5TB drives that I use for storage, the array is mounted at /Storage. I am running out of space in the array so I ordered two more 1.5TB drives to create a 4 drive RAID 1+0 array which will be 3TB big. My question is how do I create the new array and not lose any data?

The drives and partitions are sdc1, sdd1, and soon to be sde1, sdf1. I currently have 4 RAID arrays (md0,md1,md2,md3). I think I can create the RAID 1+0 array with the two new drives, copy the data from my current array to the new one, remove the old array, then add the two original drives to the new array. But I wanted to ask on here first to make sure my data doesn't go poof.

Server :: Recreate Raid-5 Array Without Loosing Data

Dec 11, 2010

I rebuilt a server and am now trying to recover my large data arrays. The server was ubuntu 10.04lts before. I decided to rebuild it with CentOS simply because I am more familiar with it. I had 2 raid-5 arrays on the old server:4 x 1tb -> md0 5 x 2tb -> md1 The newly built server does not know about these arrays yet. How can I reassemble the arrays without loosing my data? I know the data can still be accessed because booting the server with a live-cd mounts and shows the arrays just fine. Should I boot with a live cd and copy the mdadm config file?

Programming :: PHP MySQL Array Return Unexpected Data

Nov 8, 2010

I am trying to build an array with the column headers and the data like so:

PHP Code:
function query($query) {
$data = array();
$q = "$query";
$this->log->message("Manual query [$q], returning columns...");
$result = @mysqli_query($this->dbc, $q);
$this->selected_rows = mysqli_num_rows($result);

while($meta = mysqli_fetch_field($result)) {
while($row = mysqli_fetch_array($result, MYSQLI_ASSOC)) {
echo "meta [{$meta->name}]"; $data[$meta->name][] = $row[$meta->name]; } }
echo "DATA ["; print_r($data); echo "] <br />";
return $data; }

So I can select the data from the array like so:
PHP Code:
echo $data[col_name][row_num];

However when I dump the array I dont get the data I am expecting:
Code:
running select * from users:
meta [company_name]meta [company_name]
DATA [Array ( [company_name] => Array ( [0] => My company [1] => My details ) ) ]

Fedora Installation :: How To Use Processing.org's Processing-1.0.9 As Application?

Mar 1, 2010

New to Fedora (from Windows), I am up and running ok with packages from the repository but only half ok with Processing, the Java graphics programming front end from processing.org.Their download gave me a .tgz file which Package Manager extracted for me into a location of my choice and where there is now a "processing" shell script.This works ok and I have managed to create a launcher on the desktop. That starts ok but always with processing's default action of giving you a new and automatically named work file.In Windows an existing Processing file (.pde file) could be "opened-with" Processing. Trying to do similar in Fedora I find that I am expected to nominate an Application to open with but Processing has not installed as an application.I guess the question is how do I promote Processing to be an Application?Or is there a different approach?

Ubuntu :: Temporarily Copy Data Before Growing RAID0 Array?

Feb 1, 2011

I currently have two hard drives, with my root partition configured in RAID0. I'd like to add two additional hard drives, and include them in my RAID0 array. I need to recreate the array to do this, so I'd like to copy everything off of the existing array, add the drives, build the new array, and copy everything back. I have an external hard drive with four times the capacity of my current array. What would be the best way to copy this data so that nothing is missed, so I can just copy everything back and boot back up? dd, image the entire root partition, mount it after creating the new array, copy everything back (at the filesystem level) dd, image the entire root partition, write it back out to the new array, I'm not sure how this would work, because the partition will be the wrong size, I don't know much about dd. rsync, just rsync everything on root over to the external something else? I plan on booting to a live CD and mounting my current array there, so I won't be working on a live filesystem.

Server :: Recover RAID5 Storage Array DATA Using Xfs_repair?

Jul 5, 2011

I have an Acer Altos EasyStore SATA NAS box that hung, the only way to reboot was to crash the system (unplug it). Upon reboot it was not recognising the hard drives (it wanted to do a destructive reinitialize). Most of the importent data was backed up, however some was overlooked and we'd quite like to get it back. Removing the disks and placing them in a PC with enough SATA bays to cope, and booting with a live linux distribution (System Rescue CD) I can see the 4 drives are not suffering hardware error and that the original partions exist. Using mdadm I can assemble the Arrays without error (seems to be three but the only one I am concerned with is the RAID5 array of about 3TB). /dev/m1p2 mounts as a loopdevice once an offset is entered. In turn this mounts as an XFS parition. However despite df showing the partition almost to be full. ls -l or ls -a on the mount point shows it to be empty!

I got thusfar using a translation from a German language forum, unfortunately I only speak a little German, and the only other English language post on a simlilar matter I found within that site had no replies. The next step was to unmount loop, then run xfs_chack and xfs_repair on the file system. xfs_check returns that there is are a few dir size and offset errors along with link count mismatches. This I would presume normal for a file system that has become slightly corrupted. xfs_repair (version 3.0.3) gets as far as Phase 3 it finds and corrects zerolength entries, offsets on directories and bogus inode numbers. However the final two lines are:

Code:

realloc failed in blkent_append (2671166480 bytes)
zsh: segmentation fault xfs_repair /dev/loop1

A search on the error missing out data size just returns code to generate it, is anybody able to explain what it means? Also remounting hard drive, ls and varients of still do not return anything. Am I missing some thing (root I am logged in with now would have different credentials presumably to root on the NAS box, so how do I get around this)?

General :: Find Contents From Recycle Bin That Were Put Into One Folder - Name Unknown?

Oct 13, 2010

Recently I did a System Mechanics clean-up of invalid and other misc files. The files were moved to the recycle bin, but I couldn't open a file individually while it was in the recyle bin in order to double check whether or not I wanted to perminently delete it. I then selected all items and moved them to a single folder hoping to open it later to review the individual files.I don't know the folder name or what part of the computer this folder was moved to. Is there a way I can find this new folder, name unknown, that was created on 10-12-10? I'm sure it's taking up valuable space in my computer and I want to permently delete the unwanted items individually and not as a whole batch.
