  • Gnome-shell freezes. What to do to keep apps open, like "alt+f2 r" when GS works

    - by user94592
    This is a repost, because no one had popper solution. What to do when gnome-shell freezes? Everything works correctly (music is still playing etc.), just the gui freezes. I am able to ctrl+alt+f1. What can I do after logging in the ctrl+alt+f1 terminal, in order to restore gnome-shell? If gnome-shell worked, I'd just hit alt+f2 and run r. I usually end up sudo rebooting which I don't like, because I have to reopen apps.

  • I need to get past my permissions to recover data

    - by adsmz
    Due to some mishaps, I am unable to boot into Kubuntu at all. However, my data is still on the hard drive. I managed to get one of the other two computers to which I have access to read the disk by booting into a liveCD session of kubuntu. The only storage medium to which I have access is a 30 GB data stick. Here's where the trouble starts: In music alone, I have to back up about 60 GB. Obviously this is going to have to be split into chunks and moved over to the second spare PC until I can reinstall Kubuntu on my laptop. All of the data that needs backed up is behind a permissions wall, so while I can view it, I can't interact with it directly. I know copying and moving through the terminal can get around this with sudo cp or sudo mv, but is there a way to first compress multiple folders in a single archive, then move it? (While we're on the subject, what compression method would be best for large volumes of music in MP3, WAV, and OGG format?)

  • How to execute a "name.desktop" file? [duplicate]

    - by Pubudug
    This question already has an answer here: Running a .desktop file in the terminal 10 answers #!/usr/bin/env xdg-open [Desktop Entry] Version=1.0 Type=Link Name=ShareFolder Icon=/usr/share/icons/DPL/NetworkShare.png Name[en_US]=ShareFolder URL=smb://servername/sharefolder This is my .desktop file which has a URL. How do I execute this desktop shortcut in the terminal? If i double click it works perfectly, but I need to execute this in terminal. I tried Running a .desktop file in the terminal. That didn't work for me either but it does if its an "application" shortcut. I'm trying here to execute "link" .desktop file, where you define in the type section (Type=Link) and (URL=smb://servername/sharefolder)

  • echo difference between ubuntu and RedHat

    - by arcomber
    I have mostly been experimenting with ubuntu but recently was using a Red Hat Enterprise system and was surprised at a difference I found setting and displaying env variables. In ubuntu I might have an interaction like this: acomber@mail:~$ export MY_VAR=i686-linux acomber@mail:~$ echo $MY_VAR i686-linux acomber@mail:~$ echo "$MY_VAR" i686-linux But on RHEL: acomber@mail:~$ export MY_VAR=i686-linux acomber@mail:~$ echo $MY_VAR acomber@mail:~$ echo "$MY_VAR" i686-linux I know this is a ubuntu forum but why the difference? Why do I need to enclose in quotes on RH? There are no spaces in the variable name?

  • Silverlight doesn't prompt to increase quota

    - by Sung Meister
    I am trying out Silverlight's Isolated Storage feature. Currently running Silverlight thru ASP.NET page. I have written some code to request an additional storage but I am not being prompted to add more. private void requestButton_Click(object sender, RoutedEventArgs e) { using (IsolatedStorageFile store = IsolatedStorageFile.GetUserStoreForApplication()) { if (store.AvailableFreeSpace >= 1000*1024) return; long usedSpace = store.Quota - store.AvailableFreeSpace; if (store.IncreaseQuotaTo(usedSpace + 1000*1024)) statusTextBlock.Text = string.Format("Quota has been increased to {0}", store.Quota); else statusTextBlock.Text = "You have denied quota increase... you Inglorious Basterd..."; } } Silverlight's Application Storage tab doeslist the localhost ASP.NET page hosting Silverlight as shown below. According to the screenshot, http://localhost:54389 has 1.0MB of available storage area. Is there a restriction set on localhost websites that a prompt is ignored? What are the required steps for Silverlight to prompt users to increase quota?

  • Win C#: Run app as administrator without UAC prompt

    - by paja
    Hello, I need one of my .exe to always run as administrator without UAC prompt. My program will be installed with setup, which will have for one time admin rights, and I need to perform such step in this setup that my exe will be always executed as admin without UAC prompt. I've found 2 solutions so far: 1) Use custom service, which will elevate the program for me. 2) Use tash scheduler: http://www.howtogeek.com/howto/windows-vista/create-administrator-mode-shortcuts-without-uac-prompts-in-windows-vista/ Is there any other solution? Some manifest probably? Thanks.

  • Calling and leaving gnuplot prompt and png export

    - by ldigas
    a) I have a data file with, well ... data, and a .gnu file with gnuplot commands. If I call gnuplot like this: gnuplot -p commands_file.gnu I'll get the graph on screen and when I close it, gnuplot will be in it's own prompt (gnuplot_). How can I make it just show the graph, and put me back on cmd prompt after I close it ? b) How to "export" that graph to png or something insertable in Word ? I know there are a dozen tutorials for this on the 'net, but I'm having trouble just finding a simple example.

  • MFC resource.h command/message IDs

    - by ak
    Hi I'm working on an MFC application, that got pretty messy over years and over different teams of developers. The resource.h file, which contains all command/message mappings grew pretty big over time, and has lots of problems (like duplicate IDs). I am not proficient with MFC, so the question might sound pretty stupid... MSDN docs mention that Command IDs and Message IDs should not be less than WM_USER and WM_APP correspondingly. I saw that most of the command IDs in resource.h generated by Visual Studio begin around 100. Shouldn't this cause some interfering with MFC/Windows commands and messages, that overlap with the application defined IDs? For example, I have a command ID : #define ID_MY_ID 101 and there is a windows command that has the same ID. When MC send this command to the APP, it's handled like an application defined ID_MY_ID, and the app is taking unnecessary actions. Is it a possible scenario? Also, is there some third party tool that helps to profile the project resources?

  • Python doesn't work properly when I execute a script after using Right Click >> Command Prompt Here

    - by Dominic Bou-Samra
    This is a weird bug. I know it's something funky going on with my PATH variable, but no idea how to fix it. If I have a script C:\Test\test.py and I execute it from within IDLE, it works fine. If I open up Command Prompt using Runcmd.exe and navigate manually it works fine. But if I use Windows 7's convenient Right Click on folder Command Prompt Here then type test.py it fails with import errors. I also cannot just type "python" to reach a python shell session if I use the latter method above. Any ideas?

  • Graceful DOS Command Error-Handling w/PHP popen()

    - by Captain Obvious
    PHP 5.2.13 on Windows 2003 I am using the DOS Start /B command to launch a background application using the PHP popen() function: popen("start /B {$_SERVER['HOMEPATH']}/{$app}.exe > {$_SERVER['HOMEPATH']}/bg_output.log 2>&1 & echo $!", 'r'); The popen() function launches a cmd.exe process that runs the specified command; however, if the command fails (e.g. the {$app}.exe doesn't exist or is locked in the above example), the cmd.exe process never returns, and PHP hangs indefinitely as a result. Calling the failing DOS command directly using the Command Prompt results in an Error prompt that requires clicking the OK button. I assume this error confirmation requirement is what's preventing the cmd.exe process from returning to PHP both from the Command Prompt (using both CGI and CLI) and the web (using Apache 2.0 handler w/Apache 2.2). Is there a way to configure PHP, Apache, and/or Win 2003 to return the DOS error to the originating call rather than waiting for confirmation?

  • Javascript for a prompt which accepts simple math as a value and then returns the answer

    - by user1139403
    I have written a snippet of code in javascript, for a prompt to appear when clicked. I want to be able to enter a simple math problem (i.e. 230/2) and have it output the answer, rather than the math problem I just entered. Your help will be much appreciated. <!DOCTYPE html> <html> <body> <button onclick="myFunction()">Click me</button> <p id="demo"></p> <script type="text/javascript"> function myFunction() { var x; var mathProblem=prompt("Enter your math problem",""); if (name!=null) { x = mathProblem; document.getElementById("demo").innerHTML = x; } } </script> </body> </html>

  • Subprocess with variables & Command from different class

    - by Pastelinux
    source: http://pastebin.com/utL7Ebeq My thinking is that if i run from controller class "main" it will allow me to take the "data" from Class "model", def "filename". It doesn't seem to work. As you can see below what i mean class Controller: def __init__(self): self.model = Model() self.view = View() def main(self): data = self.model.filename() self.view.tcpdump(data) class View: def tcpdump(self, command): subprocess.call(command.split(), shell=False) When i run my code i get this error: subprocess.call(command.split(), shell=False) AttributeError: 'NoneType' object has no attribute 'split' My guess means that its not picking up command (look at source for reference) or that its not getting command with variables. But i know the error when variables are not being picked up so i don't think it is that. My question is, from what i have thus far, how do i from "class view" grab "command" for my subprocesses to run. Thanks~ John Riselvato

  • Emacs: print key binding for a command or list all key bindings

    - by Yktula
    In Emacs (GNU 23.2, *nix), how can I: list the key sequences bound to a particular command? For example, how can we list all the key sequences that execute save-buffers-kill-emacs, with the output of key sequences bound to it? Assuming we can do this, listing the key sequences bound to goto-line should print the output: M-g g on a default install. list all key-bindings? Does C-h b do this? Would it print my own bindings? I am aware that executing the command directly can print a key sequence it can be activated with, but it doesn't always do so, and a few things happen, including: (1) the output doesn't remain for long, (2) the command is executed. I want a command that lists for me (preferably all) the bindings attached to a given command, without executing the command, or something like that.

    I am trying to run a java command like this in a PHP Joomla Component. It works, however, the files generated from the command are written to /administrator and I want them to be written to the location where the Java command resides ie. /administrator/com_mycomponent/java/MyJavaApp.jar //run the command $javaCommand = "$javaCommand -jar $keyGeneratorFile $appName"; $response = exec($javaCommand); if(empty($response)) { JError::raiseError(500, "Key Generation failed for command: $javaCommand"); } What can I do?

  • Batch Script to Trim lines in text to first 30 or 50 characters only

    - by SuperUserMan
    I am now new to scripts but i find it really difficult understanding "for" command (especially with that tokens and delimiters etc) . Saying so, i think that for command can be used to do what i am doing. If its not and there is an easier way, ignore my ignorance :( Say i have multiple lines in a text file abc.txt with each line starting and ending with " (quotes) E.g. a file of 3 lines "hey what is going on @mike220. I am working on your car. Its engine is in very bad condition" "Because if you knew, you'd get shredded and do it with certainty" "@honey220 Do you know someone who has busted their ass on a diet only for results to come to a screeching halt after a few weeks" How can i trim each line, within the quotes, to a Fixed length say 30 or 50 or 100 characters (including spaces) I want to enter the number of character in batch and it can trim accordingly and produce a file def.txt with trimmed lines within quotes. Say i enter 50, results of above example should be "hey what is going on @mike220. I am working on you" "Because if you knew, you'd get shredded and do it" "@honey220 Do you know someone who has busted their" Thanks P.S. if you use For command, kindly please explain the command. EDIT: Though the answer provided worked, there is an issue with non english text. I am getting garbled text in Output file for non english text in input file . Any help @barlop here is the nonenglish text ( 1 line) "???? ?? ???? ?? ???? ???? ??? ?????? ???"

  • Does OS X support linux-like features?

    - by Xeoncross
    I have been using XP for almost a decade. Contrary to popular belief, it has served me well. In the last 4 years I don't remember ever having it crash on me. It has the most stable GUI I have ever used. However, an OS is only as good as it's GUI AND command line combined. Windows command line is awful and totally useless. So I have been using Ubuntu for a couple years and Debian on my servers. The only problem is that Gnome applications (ubuntu 6-10) constantly crash on me (Ubuntu Studio was the most unstable OS I ever used). I have high quality Gigabyte, MSI, and Asus motherboards and CPU's from old Semprons/Athlons to Celerons/Core 2 Quads. What are the odds that every PC I have ever owned can't remain stable with a linux GUI? Not to mention that Adobe CSx Suite doesn't work on linux. Anyway, I am now looking at moving to a MAC in the hope of finding a stable GUI and a feature-packed command line. Does Mac OS have an integrated command line where I can do linux-like-awesomeness like rsync, ssh, wget, crong jobs, package updates, and git without having an unstable GUI? Basically, until the linux GUI applications get a little better, is OS X what I need?

  • What is the difference between PS1 and PROMPT_COMMAND

    - by Jed Daniels
    While taking a look at this awesome thread I noticed that some examples use PS1="Blah Blah Blah" and some use PROMPT_COMMAND="Blah Blah Blah" (and some use both) when setting the prompt in a bash shell. What is the difference between the two? An SO search and even a bit of broader google searching aren't getting me results, so even a link to the right place to look for the answer would be appreciated. Thanks!

  • Conditionally create symbolic link by filesize using find exec ubuntu 10.04

    - by jmlw
    I have an interesting problem. I'm trying to create symbolic links in a single folder, for all files in a directory which are larger than a specified size. For clarification, here is an example: /Files /Large_Files /LargeFile1_symlink /LargeFile2_symlink /Folder1 /file_a /file_b /Folder2 /LargeFile1 /Folder3 /LargeFile2 /file_c What I have so far to try to accomplish this is: find -size +102400 -exec ln -s $PWD/{} Large_Files/ \; However, this find produces ./LargeFile1 So my symlink command produces ln -s /Files/Folder2/./LargeFile1 Large_Files/ My question is, would it be possible to use the basename command to separate out only the filename so this command will work? Or does anybody have a suggestion on how to do this without writing a script, or give me an example on writing a script? I've never done scripting before, but I do know Java, but don't want to take the time to do all this in Java. Thank you for any help! Edit: adding tags

  • Scripting a Windows 2008 Cluster from Windows 2003

    - by glancep
    Our current environment is all Windows 2003. When we migrate a new version of our service to the cluster, we first stop the service with a command like: cluster.exe <clusterName> resource "<serviceName>" /offline We do similarly after the migrate to bring the service back online. Now, we are upgrading our environment to new Windows 2008 servers. However, our build/migrate machine will remain Windows 2003. When issuing the same command from Windwos 2003 to Windows 2008, we get: System error 1722 has occurred (0x000006ba). The RPC server is unavailable. We need to be able to remotely administer a Windows 2008 cluster from a Windows 2003 server in an automated fashion (such as the command-line cluster.exe utility). Is this possible? Thanks, Gideon
