  • Django shell command to change a value in json data

    - by crozzfire
    I am a django newbie and i was playing around in django's manage.py shell. Here is something i am trying in the shell: >>> data [{'primary_program': False, 'id': 3684}, {'primary_program': True, 'id': 3685}] >>> data[0] {'primary_program': False, 'id': 3684} >>> data[1] {'primary_program': True, 'id': 3685} >>> data[0].values() [False, 3684] >>> data[1].values() [True, 3685] >>> How should i give a command here to update the value of primary_program in data[1] to False and keep the rest of the json the same?

  • Linux servers going into Halt when pressing Control-D in putty or exit in the shell

    - by Itai Ganot
    Since today at noon, there's a number of Linux CentOS servers which are going to Halt whenever i type exit or use Control-D to close the putty window. Did anyone encounter this weird behavior before? I've checked the aliases list on the servers and there is no alias regarding halt command. After the server came online i've checked the history and saw a "logout" command there but nothing which is related to Halt. At first, i thought it happens only from my computer but later i realized that it happens to everyone which types exit, logout or control+d. 2 of these server are our main iptables firewalls and so it's super critical, your assistance is much appreciated. It looks like that, and it only happens on servers with active IPTables: [root@srv1 bin]# ssh srv2 root@srv2's password: Last login: Sun Nov 11 17:19:41 2012 from 192.168.12.98 [root@srv2 ~]# vim /etc/crontab [root@srv2 ~]# exit logout Broadcast message from root (pts/1) (Tue Nov 13 10:44:04 2012): The system is going down for system halt NOW! Connection to srv2 closed. [root@srv1 bin]# In my troubleshooting steps i came across the command strace, and so i've opened two bash windows to one of the problematic server and i used strace -p PID_of_bash. When i typed in exit in the first shell it did go to halt, attached is the strace output, if you can check it out and tell me if you see anything suspicious i'd be more than thankful.

  • How do I execute a shell-command in background?

    - by Adobe
    Here's a simple defun to run a shell script: (defun bk-konsoles () "Calls: bk-konsoles.bash" (interactive) (shell-command (concat (expand-file-name "~/its/plts/goodies/bk-konsoles.bash ") (if (buffer-file-name) (file-name-directory (buffer-file-name))) " &") nil nil)) If I start a program with no ampersand - it start the script, but blocks emacs until I close the program, if I don't put ampersand it gives error: /home/boris/its/plts/goodies/bk-konsoles.bash /home/boris/scl/geekgeek/: exited abnormally with code 1. Edit: So now I'm using: (defun bk-konsoles () "Calls: bk-konsoles.bash" (interactive) (shell-command (concat (expand-file-name "~/its/plts/goodies/bk-konsoles.bash ") (if (buffer-file-name) (file-name-directory (buffer-file-name))) " & disown") nil nil) (kill-buffer "*Shell Command Output*")) Edit 2: Nope - doesn't work: (defun bk-konsoles () "Calls: bk-konsoles.bash" (interactive) (let ((curDir default-directory)) ;; (shell-command (concat "nohup " (expand-file-name "~/its/plts/goodies/bk-konsoles.bash ") curDir) nil nil) (shell-command (concat (expand-file-name "~/its/plts/goodies/bk-konsoles.bash ") curDir "& disown") nil nil) (kill-buffer "*Shell Command Output*"))) keeps emacs busy - either with disown, or nohup. Here's a script I'm running if it might be of help: bk-konsoles.bash

  • How can invoke a shell to make a new environment to run a make inside another make?

    - by WilliamKF
    I would like in my GNUmakefile to have a target rule that invokes a new shell and then with the clean slate of the new shell invokes a new make. What is the syntax to do this? I tried this but it didn't work: .PHONY: setup setup: shell cd myDir; make; cd .. It gets infinite repeat of the following error: make[1]: Entering directory `/disk4/home/user/parent' shell cd myDir; make; cd .. /bin/sh: shell: command not found make[1]: Entering directory `/disk4/home/user/parent' shell cd myDir; make; cd .. /bin/sh: shell: command not found [...]

  • How to transform multiple line into one line in bash stdout ?

    Hello, I sometimes do this in my shell : sam@sam-laptop:~/shell$ ps aux | grep firefox | awk '{print $2}' 2681 2685 2689 4645 $ kill -9 2681 2685 2689 4645 Is there a way I can transform the multiple lines containing the PIDs into one line separated by spaces ? (It's a little bit annoying to type the PIDs every time and I really would like to learn :) ) Thanks a lot.

  • How to force emacs to use \n instead of \r\n

    - by User1
    I have to use windows to write some shell scripts. I decided to use emacs, but I get a weird error when running the script: /bin/bash^M: bad interpreter: No such file or directory Correct me if I'm wrong, but that looks like the shebang ends in \r\n instead of just \n. How can I tell emacs to only write \n? I'm in Shell-script major mode. It's quite surprising this isn't fixed by default.

  • pass commands to an running R-Runtime

    - by tiny81
    Hi, is there a way to pass commands (from a shell) to an all ready running R-runtime/R-Gui, without copy&past. So far I only know how to call R via shell with the -f or -e option, but in both cases a new R-Runtime will process the R-Script or R-Command I passed to it. I rather would like to have an open R-Runtime waiting for commands passed to it (via what ever connection is possible). regrads, Tiny

    Hi there, I'm trying to run the following line: Directions.loadFromWaypoints((Waypoint[])waypoints.toArray(), opts); But I'm getting: 23:41:44.595 [ERROR] [carathome] Uncaught exception escaped java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to [Lcom.google.gwt.maps.client.geocode.Waypoint; at com.presasystems.gwt.carathome.client.widgets.MostrarLinhasPanel$1$1.onSuccess(MostrarLinhasPanel.java:72) at com.presasystems.gwt.carathome.client.widgets.MostrarLinhasPanel$1$1.onSuccess(MostrarLinhasPanel.java:1) at com.google.gwt.user.client.rpc.impl.RequestCallbackAdapter.onResponseReceived(RequestCallbackAdapter.java:216) at com.google.gwt.http.client.Request.fireOnResponseReceived(Request.java:287) at com.google.gwt.http.client.RequestBuilder$1.onReadyStateChange(RequestBuilder.java:393) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at com.google.gwt.dev.shell.MethodAdaptor.invoke(MethodAdaptor.java:103) at com.google.gwt.dev.shell.MethodDispatch.invoke(MethodDispatch.java:71) at com.google.gwt.dev.shell.OophmSessionHandler.invoke(OophmSessionHandler.java:157) at com.google.gwt.dev.shell.BrowserChannel.reactToMessagesWhileWaitingForReturn(BrowserChannel.java:1713) at com.google.gwt.dev.shell.BrowserChannelServer.invokeJavascript(BrowserChannelServer.java:165) at com.google.gwt.dev.shell.ModuleSpaceOOPHM.doInvoke(ModuleSpaceOOPHM.java:120) at com.google.gwt.dev.shell.ModuleSpace.invokeNative(ModuleSpace.java:507) at com.google.gwt.dev.shell.ModuleSpace.invokeNativeObject(ModuleSpace.java:264) at com.google.gwt.dev.shell.JavaScriptHost.invokeNativeObject(JavaScriptHost.java:91) at com.google.gwt.core.client.impl.Impl.apply(Impl.java) at com.google.gwt.core.client.impl.Impl.entry0(Impl.java:188) at sun.reflect.GeneratedMethodAccessor9.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at com.google.gwt.dev.shell.MethodAdaptor.invoke(MethodAdaptor.java:103) at com.google.gwt.dev.shell.MethodDispatch.invoke(MethodDispatch.java:71) at com.google.gwt.dev.shell.OophmSessionHandler.invoke(OophmSessionHandler.java:157) at com.google.gwt.dev.shell.BrowserChannel.reactToMessages(BrowserChannel.java:1668) at com.google.gwt.dev.shell.BrowserChannelServer.processConnection(BrowserChannelServer.java:401) at com.google.gwt.dev.shell.BrowserChannelServer.run(BrowserChannelServer.java:222) at java.lang.Thread.run(Unknown Source) Why?

  • Java SWT - placing image buttons on the image background

    - by foma
    I am trying to put buttons with images(gif) on the background which has already been set as an image (shell.setBackgroundImage(image)) and I can't figure out how to remove transparent border around buttons with images. I would be grateful if somebody could give me some tip about this issue. Here is my code: import org.eclipse.swt.widgets.*; import org.eclipse.swt.layout.*; import org.eclipse.swt.*; import org.eclipse.swt.graphics.*; public class Main_page { public static void main(String[] args) { Display display = new Display(); Shell shell = new Shell(display); Image image = new Image(display, "bg.gif"); shell.setBackgroundImage(image); shell.setBackgroundMode(SWT.INHERIT_DEFAULT); shell.setFullScreen(true); Button button = new Button(shell, SWT.PUSH); button.setImage(new Image(display, "button.gif")); RowLayout Layout = new RowLayout(); shell.setLayout(Layout); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } display.dispose(); } } Sorceror, thanks for your answer I will definitely look into this article. Maybe I will find my way. So far I have improved my code a little bit. Firstly, I managed to get rid of the gray background noise. Secondly, I finally succeeded in creating the button as I had seen it in the first place. Yet, another obstacle has arisen. When I removed image(button) transparent border it turned out that the button change its mode(from push button to check box). The problem is that I came so close to the thing I was looking for and now I am a little puzzled. If you have some time please give a glance at my code. Here is the code, if you launch it you will see what the problem is(hope you didn't have problems downloading images): import org.eclipse.swt.widgets.*; import org.eclipse.swt.layout.*; import org.eclipse.swt.*; import org.eclipse.swt.graphics.*; public class Main_page { public static void main(String[] args) { Display display = new Display(); Shell shell = new Shell(display); Image image = new Image(display, "bg.gif"); // Launch on a screen 1280x1024 shell.setBackgroundImage(image); shell.setBackgroundMode(SWT.TRANSPARENT); shell.setFullScreen(true); GridLayout gridLayout = new GridLayout(); gridLayout.marginTop = 200; gridLayout.marginLeft = 20; shell.setLayout(gridLayout); // If you replace SWT.PUSH with SWT.COLOR_TITLE_INACTIVE_BACKGROUND // you will see what I am looking for, despite nasty check box Button button = new Button(shell, SWT.PUSH); button.setImage(new Image(display, "moneyfast.gif")); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } display.dispose(); }

  • Migrating users and mailboxes from postfix / Maildir to Postfix with Mysql backend

    - by Chrispy
    So I've got 60 or so users on a hand rolled postfix installation on openbsd and I'd like to move their mailboxes to our new mail server running iRedMail (postfix, vmail/mysql back end) Does anyone know of a good way to do this? Preferably a script I can run to keep syncing the users mailboxes as MX records get updated? I presume one way (though I don't have all their passwords!) would be to have a command line imap client that simulated the users copying their mail themselves but I'm sure there must be a shell / php script to migrate users? Anyone got any bright ideas? Chris.

  • windows 7 start menu's search "see more results" broken

    - by fluxtendu
    After searching in my start menu and clicking to "see more results", I got an error dialog: It "seems" that it should be search-ms:query=document an not search:query=document but where can I fix this? Additional info: New user account don't have the problem. Windows 7 Ultimate - RTM Disabling/Enabling again "Windows Search" (in Start Control Panel Programs Turn Windows Features on or off) doesn't fix it. (There's a HKEY_CLASSES_ROOT\Search in my registry that's not there normally.) - outdated see comments... Update: It could help me to diagnose, if someone send me any (hidden) files in %userprofile%\searches and some others pieces of registry: HKEY_CLASSES_ROOT\.search-ms HKEY_CLASSES_ROOT\.searchConnector-ms HKEY_CLASSES_ROOT\SearchFolder HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\SEARCH HKEY_CURRENT_USER\Software\Microsoft\Windows Search Any other related key that I don't have seen... Final Update: Resolved by the rastamanx answer (I can't accept the answer, because I have offer a bounty without accepted answer, vote for him please)

  • rename file names from lower case to upper case

    - by Adnan
    Hello, I have about 2k of file that are currently in lower case like: file_one.cfr file_two.cfr .... I am searching for a fast way to rename them to upper case so they would be like; FILE_ONE.cfr FILE_TWO.cfr .... If I use from my shell; for i in *; do mv $i `echo $i | tr [:lower:] [:upper:]`; done I can get all file and the file extensions to upper case. But the extension should remain in lowercase, so my approach does not work. Any programming language is welcome.

  • Crontab script on Mac OS X Lion does not work anymore

    - by Nopster
    I have a problem with cron tasks. Previously this script worked fine on Mac OS X 10.6 server, but when I initialize it on Lion (client), this script stopped working. Basically, this .bat file calls a jar file (that invokes a loop of mysqldump commands) to backup several databases on several servers, and runs perfectly if launched by the shell. cd /Users/nameoftheuser/Desktop/backupper /usr/bin/java -cp .:Backupper.jar:lib/mail.jar backupper.Main "/Users/nameoftheuser/Desktop/backupper/listasiti.txt" "/Users/nameofthe/Desktop/backupper/config.properties But if the cron launches the same .bat file, the generated database backups are 0 bytes. The cron entry is: 0 0 sh /Users/path/to/file.bat I believe that the problem is that cron doesn't run as root. Or what else?

  • Create restricted user on Debian server

    - by James Willson
    I want to create a user account for each of the key programs installed on my debian server. For example, for the following programs: Tomcat Nginx Supervisor PostgreSQL This seems to be recommended based on my reading online. However, I want to restrict these user accounts as much as possible, so that they dont have a shell login, dont have access to the other programs and are as limited as possible but still functional. Would anyone mind telling me how this could be achieved? My reading so far suggests this: echo "/usr/sbin/nologin" >> /etc/shells useradd -s /usr/sbin/nologin tomcat But I think there may be a more complete way of doing it. EDIT: I'm using debian squeeze

  • Load website and fill form from the command line

    - by Martin Scharrer
    Using the Linux command line (Bash shell) I like to load a specific website in my browser (normally Firefox, but other one would be ok as well as long it runs under Linux) and fill a pre-defined form with some data. Actually, this should run from a Makefile. Most of the form data is static and will be stored as variables in the Makefile, just some fields are to be filled manually before manually sending the form. I know how to load the website in question from the command line using: firefox <URL> But there seems no possibility to fill the form automatically with variables given on the command line. Is there a plugin, executable or JavaScript which allows me to do this? Any suggestions and hints are welcome. I don't mind coding some JavaScript.

  • Changing location of the Links folder

    - by Dany Khalife
    I am setting up a small network and i am stuck at rerouting the Links folder on Windows 7. What i am trying to accomplish is to keep some particular directories stored on a server and all client computers will actually link to those folders, one of which is the Links folder. I took a look at the registry and found most of the things in : HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders But the Links folder isn't there so im wondering if it's possible to sync that folder over several PCs too without moving all the user directories to the server Any hint is appreciated!

  • run or send a command to a tmux pane in a running tmux session

    - by cjroebuck
    I want to write a shell script which will attach to a named tmux session, select a window (or pane) in that session and run a command in that selected window (or pane). How do I do this from a bash script? I know tmux new-window -n:mywindow 'exec something' allows you to send commands to a freshly created window. But I need something like tmux select-window -t:0 'my command' I suppose I could use send-keys but seems like their should be something that takes a command or list of commands that get run.

  • Automated git push attempt does not work - authentication issue

    - by at least three characters
    I'm trying to automate a very periodic git add/commit/push cycle using a shell script and cron under OS X 10.8.5. The script is as basic as one would expect it to be: cd /my/directory git add . git commit -m "a commit message with the date" git push -u origin master I've tried running it both as root as well as a non-root user. When I do this manually, I get a dialog box from OS X requesting that I authenticate the operation. Running the script (either using cron or just using sh) ends up sending a message (via mail) to whichever user's cron executed the script saying that it was unable to write a file in the .git directory because of a permissions issue (which is most likely manual execution requires authentication). Is there any way to circumvent this issue, or give the script permission to perform this operation without having me intervene each time?

  • VIM zsh, bash and colors in command line on Ubuntu

    - by Jacek Wysocki
    I have problem with VIM command line when calling system commands. e.g. !ls, all command output colors aren't parsed by VIM. My system is Ubuntu 12.04 LTS with VIM 7.3.429 from Ubuntu repositories. Is there any workaround for this problem? EDIT: My vimrc file :!echo $TERM in VIM returns : dumb EDIT2: I found a simple workaround but it's not perfect if [ "$VIM" ] && [ "$TERM" = "dumb" ] then # For gvim's monochromatic :shell PS1='\n\u@\h \w\n\$ ' unalias ls unalias grep fi (It's working on bash)

  • How can I auto-connect to a WPA2 Enterprise network?

    - by Demetri
    I would like my computer to automatically connect to a WPA2-Enterprise network as soon as it boots whenever the network is available, without any action needed by me. The computer already offers to connect, and even remembers the password, but I must still hit 'Enter' to connect. Also, connection does not occur if my login is at the terminal. I would like to automatically connect every time I login, no matter how I do so, unless a more preferred network is available. What is the best way to do this? I am running Fedora 19. A shell script that can be invoked at the terminal would be preferred. Connecting even if the Gnome-desktop has not launched is a must.
