  • filter log file by defining regexes

    - by fmpdmb
    I have some HUGE log files (50Mb; ~500K lines) I need to start filtering some of the crap out of. The log files are being produced using log4j and have the basic pattern of: [log-level] date-time class etc, etc log-message I'm looking for a way that I can identify a regex start and regex end (or something similar) that will filter out the matching entries from the file so I can more easily wade through these massive files. I'm sure I could write a java program to accomplish this task, but I thought I'd ask the community before going down that path. Thanks in advance.

  • How do I can linux flock command to prevent another root process deleting a file?

    - by Danmaxis
    Hello there, I would like to prevent one of my root process from deleting a certaing file. So I came across the flock command, it seems to fit my need, but I didnt get its sintax. If I only indicate a shared lock, it doesnt work: flock -s "./file.xml" If I add a timeout parameter, it still doesnt work flock -s -w5 "./file.xml" It seems that way, it fits in flock [-sxun][-w #] fd# way. (What is this fd# parameter?) So, I tried the flock [-sxon][-w #] file [-c] command Using flock -s -w5 "./file.xml" -c "tail -3 ./file.xml" and it worked, tail command at ./file.xml was executed. But I would like to know, does the lock end after the command or does it last 5 seconds after the end of the command execution? My main question is, how can I prevent another root process deleting a file in linux?

    I have a windows forms app running on a machine that is not on a domain, that needs to be able to move a file from the local filesystem to a UNC path.

  • console.log() and google chrome

    - by Lorenzo C
    I'm testing a library and I use console.log() function to visualyze values. There is a strange behaviour of Google Chrome (in other browser like Firefox it doesn't happend). If I try to store strings in Array object when I log them, sometimes values appears undefined. Code example (item.name is a string) var arrayItemsSearch = [item.name]; var itemRedrawName = [item.name]; console.log("arrayItemsSearch: ", arrayItemsSearch); console.log("itemRedrawName: ", itemRedrawName); Firefox output is correct arrayItemsSearch: ["elem[0]"] itemRedrawName: ["elem[0]"] Chrome output is not correct arrayItemsSearch: [undefined × 1] itemRedrawName: ["elem[0]"] Is this a Chrome bug? Or is this beacuse in Javascript strings are immutable objects and so something that I don't understand goes wrong?

    - by Saebin
    So I want to make a batch file that will sleep my computer after a period of time. The closest thing I have found is placing it in standby, but seems to work differently then the sleep button on my keyboard (longer bootup, doesn't wake on mouse click). Any ideas? Would it be easier in python or c#?

  • Yii file upload issue

    - by user1289853
    Couple of months ago,I developed a simple app using YII,one of the feature was to upload file. The feature was working well in my dev machine,couple of days ago client found the file upload feature is not working in his server since deployment. And after that I test my dev machine that was not working too. My controller looks: public function actionEntry() { if (!Yii::app()->user->isGuest) { $model = new TrackForm; if (isset($_POST['TrackForm'])) { $entry = new Track; try { $entry->product_image = $_POST['TrackForm']['product_image']; $entry->product_image = CUploadedFile::getInstance($model, 'product_image'); if ($entry->save()) { if ($entry->product_image) { $entry->product_image->saveAs($entry->product_image->name, '/trackshirt/uploads'); } } $this->render('success', array('model' => $model)); // redirect to success page } } catch (Exception $e) { echo 'Caught exception: ', $e->getMessage(), "\n"; } } else { $this->render('entry', array('model' => $model)); } } } Model is like below: <?php class Track extends CActiveRecord { public static function model($className=__CLASS__) { return parent::model($className); } public function tableName() { return 'product_details'; } } My view looks: <?php $form = $this->beginWidget('CActiveForm', array( 'id' => 'hide-form', 'enableClientValidation' => true, 'clientOptions' => array( 'validateOnSubmit' => true, ), 'htmlOptions' => array('enctype' => 'multipart/form-data'), )); ?> <p class="auto-style2"><strong>Administration - Add New Product</strong></p> <table align="center" style="width: 650px"><td class="auto-style3" style="width: 250px">Product Image</td> <td> <?php echo $form->activeFileField($model, 'product_image'); ?> </td> </tr> </table> <p class="auto-style1"> <div style="margin-leftL:-100px;"> <?php echo CHtml::submitButton('Submit New Product Form'); ?> </div> <?php $this->endWidget(); ?> Any idea where is the problem?I tried to debug it but every time it returns Null. Thanks.

  • Printing the "source" class in a log statement with a log4j wrapper

    - by Dur4ndal
    My application has a homebrew logging class that I'm migrating to using log4j under the covers. However, since I'm using the homebrew class to pass the rest of the application's logging statements to log4j, the output statements are logged as coming from the wrapper class instead of the source class. Is there a way to ensure that the "correct" source is being shown besides creating new org.apache.log4j.Logger instances for every log statement? I've also tried using the Logger.log(String callerFQCN, Priority level, Object message, Throwable t) method, but it doesnt seem to be working, for example: public class Logger2 { public static org.apache.log4j.Logger log4JLogger = org.apache.log4j.Logger.getLogger(Logger2.class); public static void warning(Object source, String message) { log(source, message, Level.WARN, null) } private static void log(Object source, String message, Level level, Throwable t) { String className = source.getClass().getName(); System.out.println("Logging class should be " + className); log4JLogger.log(className, loggingLevel, message, t); } } When called by: public void testWarning() { Logger2.warning(new Integer(3), "This should warn"); } Prints: Logging class should be java.lang.Integer 2010-05-25 10:49:57,152 WARN test.Logger2 - This should warn

  • How to create a "copy" of SQL Server transaction log file

    - by Salman A
    I want a copy of SQL Server transaction log file for "raw" analysis. What is the safest way to get a copy of that file without shutting down the database and disturbing the existing log/backups/backup schedules and just about everything. FYI, Its a SQL Server 2000 database server and I can see the log file (its about 4GB in size) and I cannot copy it as is; I get the "access denied" error when copying from explorer or command line.
