Programming :: Filter Last 24 Hour Data And Put In New File?
Aug 30, 2010
i have file server 1 (filesvr01acess.log) and disc server 1 (discsvr01acess.log) in unix box(say ip adress of the box 10.39.66.81)
Similiarly i have file server 2 (filesvr01acess.log) and disc server 2(discsvr01acess.log) in unix box(say ip adress of the box 10.39.66.82). Now my requirement is write sheel script for ..
1. I need only last 24 hour data out of the file server 1 and file server 2 and then finaly put this data in one new file
2. Similiarly same need for discserver 1 and discserver 2.
FYI, each .log files mentioned above is nicely order as date and time as it is created. I can view through cat or search by using grep comand in unix I am wondering if we can achieve through grep command in unix

Code:
// create a filechooser;
JFileChooser chooser = new JFileChooser(cwd);
FileNameExtensionFilter filter = new FileNameExtensionFilter(
"sdf files (*.sdf)", "sdf");
[code]....
This will give 3 filefilters ('all files', 'sdf files' and 'xml files') for a fileopen dialog. Exactly as I want (in alphanumerical order), but XML is the default extension and I like SDF to be the default extension. Research has not revealed solutions; the setFileFilter method sets the primary filter. If I swap the sequence in the code, SDF becomes the default (as I want) but the sequence is wrong (All, XML, SDF).

I recently decided to try KDE4 and would like the change the clock on the panel to display 12 hour format and not the default 24hour format but i can not find where to change this option currently the clock looks like the attached picture. Gnome has this option and I would like to see it in KDE if it exists in the default clock. I am willing to replace the default KDE clock with a seperate widget if one exists for this.

I've been looking for a way to filter out emails on my postfix server by GeoIP data. I couldn't find anything that fitted the bill so wrote my own in Python as a postfix policy. Thought I'd post it here to see if it's of any use to anyone else. I've attached a tar of the files as the Python formatting will get mucked up by the forum code. Comments/improvements are welcome (be kind ) First file is : policyd-geoip which is owned by root:root and placed in /usr/bin with 755 perms

I need to change the time displayed in the task bar from a 24 hour clock to a 12 hour format. I could not find the relevant settings in OpenSuse 11.2 and same is the case for 11.3 as well.
how to make the change? I have tried System Settings ---> Computer Administration ---> Date & Time; but I was not able to make the desired change.
Similarly, I have a digital clock widget that shows GMT + 5.5 hours and I need to change that to 12 hour format as well.

I just switched over to Lubuntu, and so far, it's been great.It's rendering quite well with my laptop, even though the fan is constantly running.I've had some small annoyances that I haven't been able to figure out. How do I get the power button and/or other related actions to the 'start' menu? Is there a way to drag and drop applets like in Ubuntu? How do I setup default brightness like in Ubuntu? How do I change the time to normal US time (12 hour instead of 24 hour)How do I change the time to a 12-hour instead of 24-hour?Is there a software center?

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.

I am writting a program that reads a text file (music.txt) & stores it in a Data Structure. I am a novice learning over the internet so I this is something I have never done. How do I do this?
Quote:
Write a program that reads the data from the music.txt file and store it in a data structure. To implement this data structure you must use an array of songs and each song must be represented by a struct with appropriate fields. So far all I can do is open to file to read it (very simple I know) but so far is it correct?
Code:
#include <iostream>
#include <fstream>
#include <strstream>

I have a script which uses a Menu file (containing several different Menus). I start out with
Code:
Menu=Main
and grep my VRMenuData file for
Code:
$Menu:code:$txtring
where txtring contains the value entered from the keyboard, and cut that line for the code I want executed. So my data looks like:
Quote:
Main:code:1:declare Menu=Download
Main:code:2:soffice -calc VRSched.ods
Main:code:3:echo Load Refresh Menu here
My code acting on the data looks like:
Code:
`grep $Menu:code:$txtring VRMenuData | cut -d: -f4`
When I chose options 1 thru 3, that executes with no problem (Menu=Download does not work). The program sees into field four, but field four is not able to see outside itself. For instance:
Code:
Download:chan:
Download:pitm:1:echo $numpi. Return to Main Menu
Download:pitm:2:
[code]....
is used to generate a numbered list of channels. It could be four or 40. Whatever the number is, I want the next line to read, for example, 32. Return to Main Menu.
Code:
num
is the variable in the script I use to number the list of channels. The number following Download: pitm: is numpi, which should be added to num. How do I take
Code:
Download:pitm:1:echo $numpi. Return to Main Menu
from my VRMenuData file and generate
Code:
32. Return to Main Menu
Code:
$ declare -p Menu
declare -- Menu="Download"
$ declare -p numpi

All I want is a command that reads one data file with several columns and prints it in another one.However, whenever the value in one specific column alters, it prints one empty line in the new file. For example, consider the file
2.54000000 2.54000000
2.54000000 2.54000000
2.54000000 2.54000000
2.54000000 2.56000000

Code:
if ! [ -f ${PATH}/myfile.txt ];then
echo $(date +%Y%m%d"_"%H%M%S)": Nu am gasit fisierul ${PATH}/myfile.txt"
ps -fxu pin | grep "/usr/local/coreutils/bin/tail -f ${LOG_PATH}/x.log$" | awk '{system("kill "$2)}'
cat ${LOG_PATH}/x.log | sed -n -e '/LONG/{x;1!p;g;;}' -e h > ${PATH}/myfile.txt
[code]....
I have a continuously growing log file (x.log) in which i have to look for certain lines that contain "Long". The line above each line containing the word "Long" it contains a time stamp. I want to extract each line containing the time stamp into myfile.txt and check the difference between time stamps. Whenever there is a difference i need to run another script (${CAL_PATH}/${APP_NAME}), then sleep 1, then continue searching. Lines with "Long" do not appear continuously, but in blasts. The script runs fine until the first pause encountered. Starting with the first pause, tail -f doesn't write in myfile.txt anymore. Can someone help me understand why "tail -f" it stops writing into myfile.txt? Or does someone know an alternative to "tail -f" of achieving the initial scope of the script?

I have very little linux experience. And need some help with a bash script. I need to a script I can set cron to run to sort files out of a holding folder into final folders. It doesn't necessarily have to be bash, but I think it would be sufficient for this. File names are formatted as such when created: Dest-Date-Time-CID-Destination# I want the files to be moved from a all in one holding folder to a folder structure like this.
.../storage/year/month/day/Destination#/VarX(type)/hour/CID/'File'
I would need an if/else if/else statement to say if Dest = A set VarX = B If for example the file name was
infinity-20100927-17:00-1112223333-4445556666.wav
I would like the above file to end up moved from
.../holding
to
.../storage/2010/09/27/4445556666/Inbound/17/1112223333/infinity-20100927-17:00-1112223333-4445556666.wav
So the script will need to make directories based on information in the file name which is delimited by single dashes. Then move files from the holding folder to the newly created "sorted" folders.

Requirements are AIX tools including AWK, SED and Perl I am writing a script to check AIX users password expiration dates and if they are within the alerting period (ie. 7 days etc) it will email the user.

I am developing a program in a system where the Linux does not take care of the sync command automatically. So I have to run it from my application always I save some data in the disk, which in my case is a 2GB sdcard. It is true that I can make the operation system takes care of the syncronization, using a proper mount option, but in this case the programm's performance drops drastically. In particular I use the shelve module from Python to save data that comes from a socket/TCP connection and I have to deal with the potencial risk of the system being turned off suddenly Initially I wrote something like that to save data using shelve:
Code:
def saveData(vo)
fd = shelve.open( 'fileName' , 'c')
fd[ key ] = vo
fd.close()
os.system("sync")
But that takes too much time to save the data. Note that I use the sync from the OS every time I close a file to prevent data corruption in the case of the "computer" being turned off with data even in the buffer. To improve the performance I made something like that:
Code:
def saveListData( list )
fd = shelve.open('file_name', 'c')
for itemVo in list:
fd[itemVo.key] = itemVo
fd.close()
os.system("sync")
Thus, first I saved an amount of objects in a list then I open the file and save the objects. In this way I have to open the file just one time to save a lot of objects.However I would like to know if adding a lot of objects before closing the file would increase the risk of data corruption.I known that turning off the system after fd.close() and before os.sync may cause problems. But what about turning off the system after
Code:
fd = shelve.open('file_name', 'c')
but before fd.close()?

How can I filter ASCII quotes( ' ) and double quotes ( " ) so that I can replace them with the UTF-8 equivalent?If I copy text from a Word Document(ASCII), and upload it to a web page with PHP. The Database(UTF-8) will replace these racters with incorrect character(s).I need some function that will replace these characters but I don't know how to differentiate the ASCII quotes and the UTF-8 Quotes without (somehow) converting the string to hex, then preg_replace'ing the hex code for the symbol.
