  • Bash: Continue script if only one instance is running.

    - by Andrew
    Hello, now this is embarrassing. I'm writing quick script and I can't figure out why this statement don't work. if [ $(pidof -x test.sh | wc -w) -eq 1 ]; then echo Passed; fi I also tried using back-ticks instead of $() but it still wouldn't work. Can you see what is wrong with it? pidof -x test.sh | wc -w returns 1 if I run it inside of script, so I don't see any reason why basically if [ 1 -eq 1 ] wouldn't pass. Thanks a lot!

  • Can I set Java max heap size for running from a jar file?

    - by Kip
    I am launching a java jar file which often requires more than the default 64MB max heap size. A 256MB heap size is sufficient for this app though. Is there anyway to specify (in the manifest maybe?) to always use a 256MB max heap size when launching the jar? (More specific details below, if needed.) This is a command-line app that I've written in Java, which does some image manipulation. On high-res images (about 12 megapixels and above, which is not uncommon) I get an OutOfMemoryError. Currently I'm launching the app from a jar file, i.e. java -jar MyApp.jar params... I can avoid an OutOfMemoryError by specifying 256MB max heap size on the command line, i.e.: java -Xmx256m -jar MyApp.jar params... However, I don't want to have to specify this, since I know that 256MB is sufficient even for high-res images. I'd like to have that information saved in the jar file. Is that possible?

  • Strange Access Denied warning when running the simplest C++ program.

    - by DaveJohnston
    I am just starting to learn C++ (coming from a Java background) and I have come across something that I can't explain. I am working through the C++ Primer book and doing the exercises. Every time I get to a new exercise I create a new .cpp file and set it up with the main method (and any includes I think I will need) e.g.: #include <list> #include <vector> int main(int argc, char **args) { } and just to make sure I go to the command prompt and compile and run: g++ whatever.cpp a.exe Normally this works just fine and I start working on the exercise, but I just did it and got a strange error. It compiles fine, but when I run it it says Access Denied and AVG pops up telling me that a threat has been detected 'Trojan Horse Generic 17.CKZT'. I tried compiling again using the Microsoft Compiler (cl.exe) and it runs fines. So I went back, and added: #include <iostream> compiled using g++ and ran. This time it worked fine. So can anyone tell me why AVG would report an empty main method as a trojan horse but if the iostream header is included it doesn't?

  • Can I attach a .NET TraceListener to an externally running process?

    - by BBlake
    I am developing an application scheduling program that will run other applications using System.Diagnostics.Process. The external applications are of various types (some .NET and some not). For those external apps that have trace logging enabled, is there a way that I can attach the tracelistener of the parent/calling application to listen to and record all the trace output from the child/called application to the parent application's trace output? This is not primarily for debugging purposes. This is more to track trace output from all the various scheduled applications by collecting it into one place as much as possible. The scheduler app is still in the early design stages, but will be .NET, and I'm trying to clear up potential design issues before I get into it too far.

  • Running applictions via ruby and multi-core support? (OSX)

    - by Nick Faraday
    Hi All, I'm looking for some tutorials/resources/tips that will show me how to run applications via a ruby script. I have several small tools that we use in our day to day operations that I want to manage their tasks in one ruby script. Basically what I'm trying to do is: run app via ruby script. (wait for result) get result code (success, or error msg) if ok, start the app on its next task. Also each of the tasks are independent so I'd like to take advantage of the 8 cores on my MacPro and run 8 instances at a time. Any resources you could point me towards would be greatly appreciated!

  • Is it possible to use maven only for running selenium plugin?

    - by tputkonen
    Our pom.xml currently contains both the build settings, as well as execution of selenium using selenium-maven-plugin. I would like to split it in to two pom files, one for the build and unit tests and the second one for executing selenium tests. (This way I could first build the project in Hudson, and after successful build execute Selenium tests using another project). Is it possible to configure maven to only execute the selenium-maven-plugin?

  • Java ME Application running fine in Emulator but crashing when deployed to N70. Any way to identify

    - by sana
    I have developed a Java ME application for CLDC platform. It works fine when executed in an emulator. But when i deploy it to my N70 phone the application doesn't start at all in the phone. In my application there are some 14 classes and am creating an instance of each and putting them in the vector on application start. The classes just have one variable and 2 methods. Can this creating of lot of instances be the reason for its crashing? Is there any way I can find out the reason why the application is not able to start in the phone?

  • How can I prepare a cake graph in excel with a result based on 100%?

    - by Pitto
    Hello my friends... I need to distribute correctly a little data in an excel graph. I have the total I've earned last year which should represent the 100% of the cake. Then I have my insurance expenses and I want to understand, graphically, how much of my total income went away to pay insurance... I know that a basic proportion like: total expenses : total insurance costs = 100 : x do the correct math but I can't find a way to display this in a cake graph... Any hints?

  • Trying to get codeblocks working on Mac, running Lion. Can't get the compiler set up properly

    - by tjtoml
    First off, sorry if this is a stupid question. I installed code::blocks to try and get to know the program and start working on teaching myself c++. I have a MacBook Pro with OS 10.7.3. I ave code::blocks 10.05. When I try to build a "Hello world" nothing happens. Based on some googling I've figured out that it's because code::blocks doesn't know where to find the debugger/compiler. Further googling yielded me this page which tells me to install Xcode and to fix some things in the code::blocks settings. However, this wiki obviously has not been updated since Apple went to the App store, because the file paths it gives for the compiler do not exist (there is no /Developer/* even after installing Xcode). Xcode 4.3.2 was already installed when I installed code::blocks and code::blocks "auto-detected" several compilers. They did not work. If anyone knows where Xcode hides its compilers now that Apple has moved to the app store, I would be much obliged.

  • Why would I see PHP NOTICE and ERRORs when running a script as a regular user, but not as root?

    - by Shawn
    As far as I can tell, there's no difference between the error reporting or message redirection between users. They both use the same PHP ini. However, when I run a script as a regular user, I get tons of NOTICES, when run as root, I get none. When starting PHP interactive mode as a regular user, I get two PHP Warnings that 'memcache' and 'xmlwriter' are already loaded; when starting as the root user, I get no warnings. I know that I should be fixing the warnings, not "making the warnings go away;" that's on the ticket. The question is, Why are the users treated differently? Why does a regular user get notices and warnings, but root does not, even if their error reporting are the same?

  • shell_exec syntax error. running in terminal directly is ok

    - by Alex
    Having this command: $command = "diff -bBdH --ignore-all-space <(echo 'hi') <(echo 'hi1')"; echo $command; $result = shell_exec($command); On the screen I see: sh: 1: Syntax error: "(" unexpected diff -bBdH --ignore-all-space <(echo 'hi') <(echo 'hi1') If I copy-paste the second line from the console output into the terminal, the result would be correct. (Reproduced on another machine too). I'm missing something dead simple here and can't see what it is. besides, why is my output reversed? I'm clearly echoing the command before executing it, thus the syntax error of the shell should appear after the shell_exec

  • Grails: GGTS not running on Amazon AWS EC2 anyone else successful?

    - by Anonymous Human
    Im just curious if anyone has had success trying to run the Groovy Grails tool suite on an Amazon AWS EC2 instance with its display exported into your windows machine. If so, I wanted to know which flavor of linux was used on the EC2. I am not having much success with it on the Amazon Linux but haven't tried their Ubuntu instances yet. I got all the way to getting GGTS installed and getting the display exported but when I launch GGTS I get log errors about libraries missing. This is most likely because I didn't use yum to install it so I am probably missing dependencies but I didn't have a choice its not offered as a yum package. Here are my log file errors when I try to launch GGTS: !SESSION 2014-06-08 03:08:04.873 ----------------------------------------------- eclipse.buildId=3.5.1.201405030657-RELEASE-e43 java.version=1.7.0_55 java.vendor=Oracle Corporation Framework arguments: -product org.springsource.ggts.ide Command-line arguments: -os linux -ws gtk -arch x86_64 -product org.springsourc e.ggts.ide !ENTRY org.eclipse.osgi 4 0 2014-06-08 03:08:12.116 !MESSAGE Application error !STACK 1 java.lang.UnsatisfiedLinkError: Could not load SWT library.
