I am trying to extract data from the xml file using c coding. here is the sample code. this code gets compiled with errorfree. but the call back functions start and end are not invoked. coding:
#include<stdio.h>
#include<string.h>
#include<expat.h>

I use Lenny, and was trying to mount a .iso image, supposedly a cd imagem.
[code]....
This is what I get from dmesg | tail:
debian:/home/zac/cscd# dmesg | tail
[ 1811.505199] floppy0: disk absent or changed during operation
[ 1811.505207] end_request: I/O error, dev fd0, sector 0
[code]....
I did a little research on the web and it seems that this file is not really a cd image, but simply data in a .img file. What do you think of that?
debian:/home/zac/cscd# file cscd3.iso
cscd3.iso: data
Some people recommend to extract the data via the dd command, but it didn't seem very safe for me to do that!

is it possible to extract the data into a directory (instead of a device) using dd? This file is supposed to be a software. I wanted to run it on wine by keeping it mounted on a mount point in my file system. Does it make any sense to try to do this if the file simply isn't a cd image?
My OS is Fedora 14 - 64bit. I want to extract and install this file "LEXMARK-INKJET-LEGACY-wJRE-1.0-1.x86_64.rpm.sh.tar.gz". At the moment this is in the download box in the top left corner of my monitor.
I have tried several ways, but all I get is Command Line Output. Gzip:stdin: unexpected end of file./bin/gtar: unexpcted EOF archive. /bin/gtar: error is not recoverable: exiting now.
I have come across a webpage where there are several (thousands of hyperlinks). Of those hyperlinks, many are named "CDS" and in each of these CDS hyperlink- there are certain lines which i need to chop off!! I kind of have this feeling that AWK would be the one to use.

my major problem with it however , is the way the cache is stored on the hdd , now everything is sort of "sorted" into an endless number of folders.
i'm wondering why did they do it that way ? how are we supposed to browse the cache folders from now?
btw i've always resorted to the cache folder for extracting all kinds of things the browser downloads..
Code for insertion of data:
Code:
#include <map>
#include <iostream>

I don't know how to fetch the data from the nested map here.
I am trying to develop a method of reading files generated by other programs. I am trying to find the most versatile approach. I have been trying bash, and have been making good progress with sed, however I was wondering if there was a "standard" approach to this sort of thing. The main features I would like to implement concern reading finding strings based on various forms of context and storing them to variables and/or arrays. Here are the most general tasks:
a) Read the first word(or floating point) that comes after a given string (solved in another thread)
b) Read the nth line after a given string
c) Read all text between two given strings
d) Save the output of task a), task b) or task c) (above) into an array if the "given string(s)" is/are not unique.
e)Read text between two non-unique strings i.e. text between the nth occurrence of string1 and the mth occurrence of string2
As far as I can tell, those five scripts should be able to parse just about any text pattern. I am by no means fluent in these languages. But I could use a starting point. My main concern is speed. I intend to use these scripts in a program that reads and writes hundreds of input and output files--each with a different value of some parameter(s).
The files will most likely be no more than a few dozen lines, but I can think of some applications that could generate a few hundred lines. I have the input file generator down pretty well. Parsing the output is quite a bit trickier. And, of course, the option for parallelization will be very desirable for many practical applications.
I have a remote Debian 5 machine on which I'm trying to extract a tar-file (Django 1.2.1, but that's unimportant). The first 1300 or so files extracts just fine (of about 2800 in total), after which errors liketar: Django-1.2.1/tests/urls.py: Cannot open: No such file or directoryshows up for the rest of the files, finally ending up with atar: Error exit delayed from previous errorsI use the commandtar xzvf Django-1.2.1.tar.gzI've also tried with sudo (but I'm extracting in my home directory, which I should obviusly have permissions to use without). I've tried gunzipping first (runs flawlessly) and then running tar xvf, but to no avail. I've fetched the file using wget:

I just need to find a way to extract my file.
I'm trying to extract a file from a zipped archive, and receive an error message saying "caution: filename not matched:".
I suspect the route cause of this is that the original filename contained accented characters (which now show as question marks in the zipped filename). I've tried renaming the file in the archive, but get the same error.

I'm trying to extract the audio from an mp4 video file and convert it to mp3 using ffmpeg. The problem is that the resulting audio file is only 3m2s long, whereas the video file is 8m15s long. Anyone know why the audio file is being truncated? Am I doing something wrong? Apart from being truncated the mp3 file plays perfectly. Here's what ffmpeg has to say about the video file:
Code:
Seems stream 1 codec frame rate differs from container frame rate: 59.83 (59834/1000) -> 29.92 (359/12)
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'Part1.mp4':
Duration: 00:08:15.60, start: 0.000000, bitrate: 541 kb/s
Stream #0.0(und): Audio: aac, 44100 Hz, stereo, s16
Stream #0.1(und): Video: h264, yuv420p, 1152x720, 29.92 tbr, 29.92 tbn, 59.83 tbc

There are some log files that I wish to get some information from (Apache Access Log) but it is huge! All I need as of right now is any information from date and time A to date and time B. What commands can I use to extract this information from the access_log and put it into another file with just that information? I created a file called "access_info" by doing
Code:
touch access_info
but I was not sure where to go from there.
I have a file which looks something like this:
##########
some
text
text also includes empty lines
##########

more

Basically all sections are separated by 10 hashes and I need to somehow only print all lines in the last section (the "some more text" part in the example above"). I tried all kind of things with sed and awk but I didn't find any way to identify the last "section".

View 2 Replies View RelatedI am trying to extract just a few files/folders from a Time Machine backup, but can't seem to find them. The drive is automatically mounted in Ubuntu, and am able to access after enabling view hidden files, the HFS+ Private Data Directory. But that is a jumbled array of thousands of numbered folders, with each taking a fair amount of time to open on this aging Dell running 10.10.
I've tried running the standard Places - Search for Documents, with 'Show hidden and backup files' enabled, but that won't pull up any of the search times I'm going for (and seemingly won't find anything at all on the drive). So, is there any way to decipher the directory tree so as to be able to access this data from Ubuntu? Or perhaps a file embedded somewhere in there that lists out the original structure, so that I can use it as an index to see what number correlates to what originally named folder?
I've just downloaded a vidio from ..... and converted it to an .avi file. What I want, however, is just the soundtrack as an .mpg to add to my mp3 player. I'm sure Fedora has software to do this, but I don't know enough about audio/video editing to know where to look.

View 1 Replies View RelatedWe purchased a new database system at work last October, ditching the old system because of a lack of support from the vendor. This is a retail Point of Sale and Backoffice database system. I am not sure what system the new one runs on, but the system we replaced was a Firebird data base. The reason I am posting is because we are now in need of the information contained in the old database which was not completely imported into the new system.
Basically the problem is this: The database in on a Windows XP system and I found a copy of SQL Manager Lite 2008 on the system, which after quite a bit of studying, I figured out how to extract the database into a removable file. I have this file (178MB) on a USB stick in a file called Backoffice.fbd.
My studying suggests to me that I can get into this database with MySQL. I have never used this and have no clue how to do this. All I want to be able to do get into the database and create tab deliminated spreadsheet files for each of the database sections (Customers, Repairs, Sales History, stock files, etc.) Is it possible to do this with Ubuntu and MySQL and if so, can expert suggest one or two things to get me started. While a guided tutorial would be nice because I am not an expert, I am willing to learn on my own if someone could point me in the right direction.
After having downloaded unrar, I find I can't actually use it to extract rar files. Whenever I use the command unrar e filename.rar, (obviously using the correct filename), I just get told there's no such file or directory.

I have downloaded a 2 part .RAR file, and when I used to use them in Windows, I would tell WinRAR to extract the first part, and then it would automatically start extracting part 2 if it was in the same directory. When I try to do the same in Xarchiver it tells me "An error occurred! Please check the 'Store archiver output' option to see it." I don't know what 'store archiver output' is or how to access it. What do I need to do to extract both components and successfully join them?

First question is - Anyone know how i can access data in this DD file even though its been encrypted?
Second question - Is there a DD command where i can image the systems memory? I ask this because when a system is turned on, to get past the pre-boot authentication stage you need a password. From what i understand, this password will be passed in to ram when power is applied to the system. Making a copy of the memory will also copy the password?

I tried these commands:

Both show this error:
Error: can't find specified sfx module
System error: E_FAIL
I have all the .sfx modules on /home/username/.sfx/ because I use them previously with "rar" and it worked fine, but it's not working for 7zip. I also copied 7z.sfx to /usr/local/etc/ to test the second command like shown here but I get the same error.
