Programming :: Reading Lines Within A File (Perl)?
Mar 16, 2011I am trying to read certain lines within a file and give the output of the certain lines that dont equal my value, I think showing you would be easier. There is multiples of these inside one file...
Code:
LV Name /dev/vg00/lvol1
LV Status available/syncd
LV Size (Mbytes) 300lable/syncd
[code]....
I want to read everything in the file, if the status is not available then it should display the name (directly above status). If they are all availbale then do nothing. I think I know how to do it which includes putting the info in string form and placing in hash but it is proving to be out of my skill range.
Programming :: Reading Specific Lines From A File?
Sep 10, 2009To save on the writing of WAY to many files with very little in them, I want to put it all in one file and read a specific few lines. There will be six variables to be read at a time. Format is as such:
//Set 1
string name
5
12
[code]....
From name to 5th number is a set. The name will be of different lengths for each set. This will be a big file of probably 40+ sets. My problem lies in reading one and only one set be it set 5 or set 34. It needs to be done in C++.

Feb 10, 2011I 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.
Programming :: Dynamic List With Different Type - C++

Sometimes this works and sometimes I got "segmentation fault".
I think I'm doing it wrong, cause these objects have different sizes, so I don't know if I could have all of them in a single array.
Programming :: Bash - Reading Csv Delimited File To Array And For Further Manipulation?
Jan 6, 2010I am trying to do this:
1. Read csv delimited file line1 and store all values in array
2. Use the values stored in the array and replace values in other text file with them
3. read line2 in the cvs file and repeat the process
4. Do above for all lines in the cvs file
for example:
file1.cvs content:
text1,text2,text3,"text 4"
a1,a2,3,"a 4"
file.txt content:
some text $array1$ some text
some text $array2$ some text
1. read line 1 - text1,text2,text3,"text 4" put each value in array X[] lines that contain spaces in cvs will have double quotes
2. read x[1] and replace value $array1$ (in file.txt) with x[1]read x[2] and replace value $array2$ (in file.txt) with x[2] and so on
Can above be accomplished in BASH and how?

View 5 Replies View RelatedDebian Multimedia :: Make A Dialog With Zenity Which Would Show An Updating List?
Jan 4, 2011Is there a way to make a dialog with zenity which would show an updating list? Zenity does it with progress, but I didn't figure out if it's possible to do it with the list. I.e. for example, I want to monitor something, and update the dialog with new list periodically. Is it even possible? zenity can wait for data from stdin, but it just adds stuff to the list. May be there are some control sequences which clear the list in the dialog?
For example:
{ echo "Foo"; sleep 2; echo "Bar"; } | zenity --list --title='Dynamic list?' --text='Some data' --column='values'
How can I instead of adding Bar, replace the Foo with it?
Server :: Remove Dynamic String Across Multiple Lines And Files?
May 13, 2011My server was hit with an injection script which has placed code across many of my clients files. I need a script that can remove a block of php code that spans multiple lines, multiple directories/files and is dynamic, meaning that part of the code changes. I think using find/sed is what I need but cannot seem to figure out how to get it to work.The following is the script that is being injected everywhere. The catch is that they have generated dynamic code at the start/end of the script. (I have commented the parts that are dynamically changing on EVERY instance).PLEASE NOTE: Directly following this script is the start of a valid php script that I do not want to delete.

Programming :: How To Get Zenity Progress Bar Working Properly
Apr 14, 2011I am busy writing this script to get a pixel count of a large batch of images in a directory for a research project. To do this I'm using a loop to get all the images in the directory. To make the whole procedure more user friendly for some colleagues I decided to use zenity, something I haven't yet really worked with. As not to make sure that the users don't have to watch to this blank screen during the actual processing of the images I'm trying to get the zenity progress bar working. So far the progress bar comes up but instead of changing over time it stays "empty" till all the images are processed and then becomes 100% when all images are done. What servers my needs for now, but since I am trying to learn more about zenity I was wondering how I could change the script to get the progress bar properly working? Below is the piece of script I am talking about.
Code:
cd $input #goto path of image directory
(for a in *jpg *JPG *jpeg *JPEG; do
if [ -f "$a" ]; then #was it a image file
b="$a" #set b to $a
convert -resize 1000x1000! ${b} -depth 1 -format %c histogram:info:$b.txt #get pixelcount and write to .txt file
fi
done) | zenity --progress

Debian :: Generate Directory List With Exclusions?
Aug 18, 2011I'm trying to generate a list of my music directory folder structure WITHOUT the files included. I have my music directory set up in a hierarchy of Artist>Album>Files, and I just want to generate a list of the folders because that will, in effect, output a list of what albums I have by what artists, which is ultimately what I'm after. I did some looking on the internet through various forums over the past few days and found two ideas that looked promising, but ended up being not exactly what I needed. The first was to generate a .txt file based off of a shell ls command:
ls -R [music directory name] >> ~/mymusiclist.txt
That's great, except that it also includes the 40,000+ individual music files by name. I'm not about to invest that much time editing the files out of the list when I know there has to be an easier way.The second idea I came upon involved using the extglob function. I tried enabling extglob and using it to input a "negative wildcard" into the above method to remove anything .mp3 from the returned list, but extglob didn't play well in that context. I'm not a command line wizard, so it's entirely possible that I'm missing something fairly obvious. In fact, I'm sure I am. So this is a great opportunity for me to learn something new. If anybody knows of a command line way to do this, I'd love to know it. Or, even better, if anybody knows of an app that can do this, even better. I'm not above installing a secondary music player just to import the library once and get my list.
