Programming :: Create Inverted Files To Associate Files To Numbers ( Numbers Being The Index Of My Paths )?

Apr 4, 2011

am writing a small search program for my class. I have decided to use indexing for my program. Ive researched online about indexing and how search engines do it. If im gonno do that I need to create inverted files to associate files to numbers ( numbers being the index of my paths ) . Now I was wondering what would be the best way to create an inverted file ? I was going to create sql tables using mysql api in C but then again there is no array data type or vectors to store few numbers in a single column in mysql and it is not advised to use Enum or SET

Ubuntu :: Log Files - Numbers In Brackets Mean And .0's?

Feb 18, 2011

On startup, I get messages which look like this:


What do the numbers in brackets mean? (I tried looking, but I don't know how to start to search for the answer to that without being too vague). I've noticed they're nearly always progressive (increasing). Do they just refer to the event number? And in my log file viewer, why is there a dmesg and a dmesg.0?

General :: Find Files In A Directory That Contain Numbers?

Mar 1, 2011

I am trying find files in a directory that contain numbers. I have tried ls /etc *[0-9]* but that doesn't work. If I cd to /etc and run ls *[0-9]* it almost works but it also includes results from within files. My last thought was to try: find /etc [0-9] -type f but this does not work either. My second problem is that I am trying to get list of files in a directory that were changed less than 10 hours ago, using grep, while leaving out directories. I am completely stuck with the second problem.

General :: Nas - Most Effective Backup Software -> When Dealing With Large Numbers Of Files?

Jul 18, 2010

I have two NASes. I work off of one, and the other is used as a backup. As I have it set up now, it's slow. Running a backup takes a week. Even for 7 TB, with 1,979,407 files, this seems a bit outlandish,particularly as both systems are RAID-5 and the network is all gigabit. I've been digging about in the rsync man pages, and I really don't understand what differentiates the various topologies.Right now, all the processing is being done on the backup NAS, which has the main volume from the main NAS mounted locally over SMB. I suspect that the SMB overhead is killing me, particularly when dealing with lots of files.

I think what I need is to set up rsync on the main nas as a daemon, and then run a local rsync client to connect to it, which would hopefully allow me to completely avoid the whole SMB-in-the-middle affair, but aside from mentioning that it's there, I can find very little information on why one would want to use the daemon mode for rsync.

Here's my current rsync command line: rsync -r -progress --delete /cifs/Thecus/ /mnt/Storage/input? Is there a better way/tool to do this? Edit:Ok, to address the additional questions: The "Main" NAS is a Thecus N7700. I have additional modules installed that give me SSH, and it has rsync, but it's not in the $PATH, and I havn't figured out how to edit the local $PATH in a way that persists between reboots. The "Backup" NAS is a DIY affair, built around a 1.6Ghz Via Mobo with a Adaptec Hardware RAID card. It's running CentOS 5 with a full desktop environment. It's the hardware I'm running rsync from. (Gigabit is through a additional PCI card).

Further Edit: Ok, got rsync over SSH working (thanks, lajuette!).I had to do a bit of tweaking on my command line, I'm running rsync with the args:rsync -rum --inplace --progress --delete --rsync-path=/opt/bin/rsync sys@ /mnt/Storage (Note: I'm specifically not using -a, because I want to change the ownership to the local account, to not freak-out SELinux)

Programming :: Perl - Interpreter For Fib Numbers

Apr 1, 2010

As some of you know that I am new to this forum. I have another problem that I got stuck on. I have this file called "Fib.rbb" and my instructor told us to write an interpreter program by using Fib.rbb.

"You are to write an interpreter in Perl for Rongs Basic Basic (RBB) as explained in class. The BNF description for RBB and a test file called Fib.rbb are part of the file which is available in the Course Documents folder on blackboard.

Programming :: Extract 2 Numbers From A Same File?

Dec 22, 2010

I am trying to extract 2 numbers from a same file and my goal is to print them both in another file, on the same line, separated with a space. I have to do that for 20 files and I would like to have therefore 20 lines like this in the output file. It would look like this :


number1_file1 number2_file1
number1_file2 number2_file2
number_1_file20 number2_file20

So far, I did only extract one number and got an output file like this :



And I did this by running a bash script with the following content :


ls execution$1$2*.* | while read filename
cat $filename | grep -e "Total aborts:" | cut -d " " -f3 >> abort$1$2.dat

$1 and $2 are just strings to identify the different files I want to consider in this loop. This script works well to extract a number which is the 3rd field of a line starting with "Total aborts:".Now, how could I change this script to do what I mentioned above (i.e. extracting two numbers from two different lines) ? The second number is the 3rd field of a line starting with "Total throughput:"

Programming :: Matching Numbers With Nawk

May 11, 2011

I am struggling to understand why nawk matches values that are either 1 or 2 digits in length, but not 100 (3 digits).

Am I missing something obvious ? Should I use substr to remove the % ?

I am sure it's something to do with character and string matching behaviour with nawk.

Programming :: Storing Numbers In QByteArray?

Dec 15, 2010

I have a program that sends QByteArray datagrams over a udp socket. I would like to have 4 bytes of the datagram that contain a 32 bit integer. When saving numbers to the QByteArray, I have tried the static function number(int) and member function setNum(int), but they convert the integer to its decimal string representation and save that in the byte array. So if the number were 10, it takes 2 bytes, if it were 10,000,000 it takes 8 bytes. This wastes space, and makes it more difficult to get the number when it is packed with a few other pieces of data in the same datagram. Is there a standard way of doing this in Qt?

Programming :: Allowing Export To Take Numbers As Variables?

Jan 26, 2011

I'm playing around with some shell scripting and I've got a directory call CS005 and I'm trying to write a script to I can locate to the directory really quick and easy.

export CS005DIR=/home/stud/0/043234/CS005

Now I get this error

CS005DIR=/home/stud/0/043234/CS005 No such file or directory.

This is because I've got numerical values within my variable.

Is there a way to allow numbers for variable names?

Programming :: Sed To Remove Non-numerics From Phone Numbers?

Jan 26, 2011

Can sed remove non-numerics (apart from an optional leading +) from phone numbers when prefixed with text that must be retained? The need is to make phone numbers exported from an Orage address book to a .ldif file suitable for gnokii to send to a mobile phone. Here are sample lines:

facsimiletelephonenumber: +91 (123) 1234567
telephoneNumber: +44 (123) 1234567

They have to end up as:

facsimiletelephonenumber: +911231234567
telephoneNumber: +441231234567

I could do it in awk but am curious to learn if sed can do it.
