  • How to install gnome desktop from dvd on Centos 6 using command line?

    - by alwbtc
    I have installed Centos 6 to Virtualbox. Although I have chosen to install General Purpose Gnome Desktop, Gnome desktop does not start. All I get is a black and white text prompt. I would like to know how I can install Gnome Desktop from Centos dvd iso image? How do I mount the dvd image to virtual machine linux? How do I install Gnome desktop from command line? If I already have Gnome Desktop installed, why doesn't it start? How can I check from command line that I have Gnome installled? This virtual machine does not have internet connection, that's why I want to install the Gnome Desktop from dvd. Best Regards

  • How to open the Quota Entries list for a given drive from a shortcut or command line?

    - by Indrek
    Is it possible to open the Quota Entries list for a given drive from a shortcut or the command line in Windows? And if so, how? I'm not talking about managing quota entries from the command line (fsutil quota), I'm looking for a way to get directly to the Quota Entries GUI rather than going through My Computer → right-click on a drive → Properties → Quota tab → Show Quota Settings → Quota Entries... I managed to find out (using Process Explorer) that the backend process is dllhost.exe, and the DLL in question should be dskquoui.dll, so it should be possible to run it directly with rundll32.exe, but I'm not sure of the exact syntax. Any ideas?

  • SQL like group by and sum for text files in command line?

    - by dnkb
    I have huge text files with two fields, the first is a string the second is an integer. The files are sorted by the first field. What I'd like to get in the output is one line per unique string and the sum of the numbers for the identical strings. Some strings appear only once while other appear multiple times. E.g. Given the sample data below, for the string glehnia I'd like to get 10+22=32 in the result. Any suggestions how to do this either with gnuwin32 command line tools or in linux shell? Thanks! glehnia 10 glehnia 22 glehniae 343 glehnii 923 glei 1171 glei 2283 glei 3466 gleib 914 gleiber 652 gleiberg 495 gleiberg 709

  • How can I convert an OpenOffice document to PDF from the Linux command line?

    - by Norman Ramsey
    I have students who, when asked for PDF, sometimes hand me an OpenOffice document or spreadsheet. file(1) can identify these documents, but I've been unable to discover how to convert them to PDF using the command line. (The man page for ooffice(1) lists an option to print a document but not to convert to PDF.) Google is unhelpful, except for giving me the uneasy feeling that this can't be done without a nifty script in a language I don't know against an API whose documentation I can't find. Can anyone help me solve the problem of converting an OpenDocument to PDF using only the Unix command line?

  • In windows xp, how can I set the default browser from chrome to IE via Command Line, without admin privs

    - by Bugmage
    Situation: 1. Need to Set the defualt browser to IE via cmd(problem) 2. Need to do a citrix login via IE(amounts to loading a url) beause it wont run in google chrome 3. then set default browser to chrome Environment: Windows XP, no admin priv's no admin priv's mean I can't touch registry Basic Steps I'm Doing: In a bat file: 1.Set default browser to IE 2.run a citrix SSO login via IE (not compatible with chrome) 3.Set default browser to Chrome 4.kill IE 5.live long and prosper So i have it all running except "Set default browser to IE" I can set the default browser to chome by using portable chrome's cmd line argument --make-default-browser but I can't undo that process. If I launch IE, it pops up that 'make ie default browser' window which stops the SSO process. So If I can disable that check via bat file, that would also work for me. Things i've tried that didn't work: shmgrate.exe OCInstallReinstallIE We are using IE8 Maybe someone can find a chrome switch that undoes default browser: http://peter.sh/experiments/chromium-command-line-switches/ thanks for the help guy's

  • How to enter a bash script at the command line, but not process the script until the entire script h

    - by MHGL
    I am performing some interactive testing using HP's QuickTest Professional and Linux. I am connecting via SSH and feeding the BASH script lines directly into the command line. The problem I'm having is that the script executes as it is entered. I'm attempting to find a way that I can feed the script to the command line, but save execution until the entire script is complete. Anyone have any experience around doing this? I'll admit, it isn't the ideal way to perform this, but it's what I'm faced with at the moment. Any other suggestions are welcome. Thanks!

  • How to open a page in Chrome from the command line, in a new tab or an existing tab as appropriate?

    - by MattH
    I'm looking for a way to open a given page in Google Chrome from the command line, with the following behaviour: If the given page is already open in a tab, navigate to that tab If the given page is not already open in a tab, open the page in a new tab and show that tab Currently when I open a URL from the command line (e.g. using "open http://godzillahaiku.tumblr.com" on Mac OS X), Chrome will always open the URL in a new tab. I end up with lots of duplicate tabs as a result, which is a minor annoyance. I'm looking for a solution that works on Mac OS X, but a non-OS specific solution would be preferable. I'd consider writing a Chrome extension for this if there's no existing solution.

  • Windows command line ZIP extraction with checksum or similar ?

    - by Alan B
    What I need to do, at the command line, is: Extract the contents of a a ZIP archive. Change an arbitrary number of the extracted files. Repeat step 1, but because it is a huge archive, only extract the archived copies of the files changed in step 2 which is much faster. Ideally the extraction in step 3 would do something like a checksum on the files on disk and only extract those where the file in the archive has a different checksum. Or maybe compare the date changed stamp on the disk file. At the minute I use pkzipc.exe which is the command-line version of PkZip. I can't see a way to do it with this though. You can extract files from the archive that are newer than the disk files, but what I want is the opposite of that in a sense.

  • How do I run multiple commands on one line in Powershell?

    - by David
    In cmd prompt, you can run two commands on one line like so: ipconfig /release & ipconfig /renew When I run this command in PowerShell, I get: Ampersand not allowed. The & operator is reserved for future use Does PowerShell have an operator that allows me to quickly produce the equivalent of & in cmd prompt? Any method of running two commands in one line will do. I know that I can make a script, but I'm looking for something a little more off the cuff.

  • How to install GRUB command-line tools on OSX?

    - by beakr
    I need access to grub-mkrescue for a project I'm working on. I know that the GRUB command-line tools come builtin to Linux, but how do I get them on OSX? Is there a package? Is it built into the system somewhere? Is there an installer? CLARIFICATION: The question is not about installing GRUB as a bootloader on the Mac. The question is about installing the GRUB command line tools to do things like create bootable disk images of other operating systems.

  • Automatic Properties, Collection Initializers, and Implicit Line Continuation support with VB 2010

    - by ScottGu
    [In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu] This is the eighteenth in a series of blog posts I’m doing on the upcoming VS 2010 and .NET 4 release. A few days ago I blogged about two new language features coming with C# 4.0: optional parameters and named arguments.  Today I’m going to post about a few of my favorite new features being added to VB with VS 2010: Auto-Implemented Properties, Collection Initializers, and Implicit Line Continuation support. Auto-Implemented Properties Prior to VB 2010, implementing properties within a class using VB required you to explicitly declare the property as well as implement a backing field variable to store its value.  For example, the code below demonstrates how to implement a “Person” class using VB 2008 that exposes two public properties - “Name” and “Age”:   While explicitly declaring properties like above provides maximum flexibility, I’ve always found writing this type of boiler-plate get/set code tedious when you are simply storing/retrieving the value from a field.  You can use VS code snippets to help automate the generation of it – but it still generates a lot of code that feels redundant.  C# 2008 introduced a cool new feature called automatic properties that helps cut down the code quite a bit for the common case where properties are simply backed by a field.  VB 2010 also now supports this same feature.  Using the auto-implemented properties feature of VB 2010 we can now implement our Person class using just the code below: When you declare an auto-implemented property, the VB compiler automatically creates a private field to store the property value as well as generates the associated Get/Set methods for you.  As you can see above – the code is much more concise and easier to read. The syntax supports optionally initializing the properties with default values as well if you want to: You can learn more about VB 2010’s automatic property support from this MSDN page. Collection Initializers VB 2010 also now supports using collection initializers to easily create a collection and populate it with an initial set of values.  You identify a collection initializer by declaring a collection variable and then use the From keyword followed by braces { } that contain the list of initial values to add to the collection.  Below is a code example where I am using the new collection initializer feature to populate a “Friends” list of Person objects with two people, and then bind it to a GridView control to display on a page: You can learn more about VB 2010’s collection initializer support from this MSDN page. Implicit Line Continuation Support Traditionally, when a statement in VB has been split up across multiple lines, you had to use a line-continuation underscore character (_) to indicate that the statement wasn’t complete.  For example, with VB 2008 the below LINQ query needs to append a “_” at the end of each line to indicate that the query is not complete yet: The VB 2010 compiler and code editor now adds support for what is called “implicit line continuation support” – which means that it is smarter about auto-detecting line continuation scenarios, and as a result no longer needs you to explicitly indicate that the statement continues in many, many scenarios.  This means that with VB 2010 we can now write the above code with no “_” at all: The implicit line continuation feature also works well when editing XML Literals within VB (which is pretty cool). You can learn more about VB 2010’s Implicit Line Continuation support and many of the scenarios it supports from this MSDN page (scroll down to the “Implicit Line Continuation” section to find details). Summary The above three VB language features are but a few of the new language and code editor features coming with VB 2010.  Visit this site to learn more about some of the other VB language features coming with the release.  Also subscribe to the VB team’s blog to learn more and stay up-to-date with the posts they the team regularly publishes. Hope this helps, Scott

  • Need some advice on CLI design, I need to provide simple but powerful command line options

    - by howtechstuffworks
    I am writing a utility that runs on RHEL5 command line. I need my command line options to be simple but powerful. I looked at the various UNIX utilities to get an idea of how simple command line utilities have to be. Do you guys suggest any documents/links that talk about command line etiquette? I am modelling my utility on top of LVM (that's all the info I can give for now). I know it's a software engineering question, but I thought it would be appropriate to post here. Please advise.... PS: I am not asking for details about getopt or command line utility parsers.....

  • Drawing line from sprite with a touch

    - by Kaizer
    I am working with cocos2d for the iPhone and I have a question about how to implement the following. I have a circle shaped sprite on my layer. When I touch the sprite and move my finger a line must be drawn from the sprite to where my finger is. When I move my finger on the screen the line must follow (straight line). When I release my finger the line should disappear. In a good looking way I should be able to restyle the line into an arrow. Can anyone move me in the right direction for this ? Kind regards

  • Package management fails in update-manager with gzip problems and compilation errors. U12.04LTS

    - by HarveyP
    Similar to but not the same as Package management system corrupted. Cannot install or remove packages. U12.04LTS (an earlier problem) with package management system. Followed all of L. D. James suggestions in his answer to no avail. This time as well as the gzip error I am also getting compilation errors. The difference may be due to a lack of compilation in my earlier problem so it may be the same error. The packages concerned are enumerated in the output from update-manager below. Also included below that is the output from apt-get -f install apt-get autoremove gives same output. Tried update without SSL updates - 9 to install and got "Unhandled Error in aptdaemon". Output number 3 below. One at a time - output 4 - is for firefox, first in the list of packages. Falls over at libssl1.0.0 despite deselection of it from update ... Tried apt-get install --reinstall dpkg which succeeded, apt-get install --reinstall tar and apt-get install --reinstall gzip both of which failed at libssl1.0.0 as ever. (as suggested by Subv3rsion elsewhere in this forum) Now cannot apt-get update with complete success even after changing server and apt-get clean - output number 5 below ... 1).
