• how to set custom interval to horizontal axis in Flex Charts

  - by Ali Syed

  Hello folks, I am trying to set custom step (interval) to my Line Chart's horizontal axis. The chart gets its data from a grid. The grid has a lot of data and it is displayed accurately but because there are so many data points the horizontal axis is screwed up. I wanted to set a step on horizontal axis so that you get an idea when you see the graph without hovering the mouse on a data point! thanks for any help! -Ali Flexi Comment Box

• horizontal scrolling only!

  - by Crippletoe

  Hi all i have a that contains a HORIZONTAL menu. the menu consists of an unordered list. i would like the div to get a horizontal scroller whenever the menu exceeds the width of the <div>. i tried using these CSS definitions for my <div>: position: absolute; width: 380px; overflow: auto; overflow-y: hidden; height: 30px; but than realized that since the menu is LIST, the different list items break the line whenever they reach the width of the <div> and move on to the next line, thus the browser doesnt see the need for a horizontal scroller (it doesnt display a vertical one as well because of the overflow-y: hidden; line) any ideas how i can create a 1 line horizontal menu which will scroll horizontally only? thank you all so much.

• How to add GUI to command-line Ubuntu?

  - by SlimGG

  I had installed Ubuntu on a VM, with a command-line only interface, now I have had enough of command-line interface experience and plan to proceed with GUI mode. But I dont want to install a fresh copy of Ubuntu with GUI mode; I want my current [CLI] to have GUI. I have Ubuntu 12.04 LTS installed as CLI, and desired to have some light-weight (less resource consuming, slow-system friendly) GUI. What are my options and how can I accomplish this?

• How to edit pdf metadata from command line?

  - by bdr529

  I need a command line tool for editing metadata of pdf-files. I'm using a Aiptek MyNote Premium tablet for writing my notes and minutes on this device, import them later and convert them to pdf automatically with a simple script using inkscape and ghostscript. Is there any command line tool to add some categories to the pdf's metadata, so i can find the pdf later (e.g. with gnome-do) by categories?

• Newlines not being interpreted when passed to php via the command line

  - by CarbonX

  I have a PHP script that I'm invoking from another shell script that sends an automated email with a message generated from the shell script. Problem is, when I send the message all the newline characters are printed into the message. How do I get them to be interpreted? sendmail.sh: /path/to/phpscript/sendmail.php "Some Message With Newlines\nHello World.\n" sendmail.php: $message = $argv[1] . "\nNewline"; $smtp->send($to, $from, $message); The odd thing is the \n after the $argv variable is interpreted and actually prints Newline on a new line, but the newlines in the $argv variable don't, I have tried wrapping the variable in double quotes among other things but so far to no avail.

• With HTML and CSS, how to have an image that is vertically aligned with a horizontal line?

  - by sungod000

  I'd like the image on the left to be adjacent to the horizontal line on the right (bottoms lining up flush). It should be responsive so that the line can change widths as needed. Right now, the image is sitting on top of the line, not beside it. Here is the HTML <div> <img src="image.png"> <hr> </div> Here is the CSS img { float:left } hr { width:100% } How to make this happen?

• Connect to bluetooth device from command line

  - by Ilari Kajaste

  Background: I'm using my bluetooth headset as audio output. I managed to get it working by the long list of instructions on BluetoothHeadset community documentation, and I have automated the process of activating the headset as default audio output into a script, thanks to another question. However, since I use the bluetooth headset with both my phone and computer (and the headset doesn't support two input connections) in order for the phone not to "steal" the connection when handset is turned on, I force the headset into a discovery mode when connecting to the computer (phone gets to connect to it automatically). So even though the headset is paired ok and would in "normal" scenario autoconnect, I have to always use the little bluetooth icon in the notification area to actually connect to my device (see screenshot). What I want to avoid: This GUI for connecting to a known and paired bluetooth device: What I want instead: I'd want to make the bluetooth do exactly what the clicking the connect item in the GUI does, only by using command line. I want to use command line so I can make a single keypress shortcut for the action, and would't need to navigate the GUI every time I want to establish a connection to the device. The question: How can I attempt to connect to a specific, known and paired bluetooth device from command line? Further question: How do I tell if the connection was successful or not?

• Running a program in background using command-line [duplicate]

  - by user291957

  This question already has an answer here: Running programs in the background from terminal 4 answers How do I run a program in the background of a shell, with the ability to close the shell while leaving the program running which should not disturb the window i am working on? Lets say my UI is having problems or for some reason, I need to boot up a program from the terminal window. The program should not disturb my window in which i am working on but it should be opened from the command line and i should be able to get access to it using the normal shortcut ALT+TAB. Even the command line should exit after running the command I tried this .... "gedit file-name & exit" this is working fine but the gedit file is opening in the foreground (let i be working on some application like mozilla. After running the command ..... gedit file is coming upwards and i have to flip to mozilla again but the command should just open the gedit file not shifting to gedit application from the mozilla window)

• XNA 2D line-of-sight check

  - by bionicOnion

  I'm working on a top-down shooter in XNA, and I need to implement line-of-sight checking. I've come up with a solution that seems to work, but I get the nagging feeling that it won't be efficient enough to do every frame for multiple calls (the game already hiccups slightly at about 10 calls per frame). The code is below, but my general plan was to create a series of rectangles with a width and height of zero to act as points along the sight line, and then check to see if any of these rectangles intersects a ClutterObject (an interface I defined for things like walls or other obstacles) after first screening for any that can't possibly be in the line of sight (i.e. behind the viewer) or are too far away (a concession I made for efficiency). public static bool LOSCheck(Vector2 pos1, Vector2 pos2) { Vector2 currentPos = pos1; Vector2 perMove = (pos2 - pos1); perMove.Normalize(); HashSet<ClutterObject> clutter = new HashSet<ClutterObject>(); foreach (Room r in map.GetRooms()) { if (r != null) { foreach (ClutterObject c in r.GetClutter()) { if (c != null &&!(c.GetRectangle().X * perMove.X < 0) && !(c.GetRectangle().Y * perMove.Y < 0)) { Vector2 cVector = new Vector2(c.GetRectangle().X, c.GetRectangle().Y); if ((cVector - pos1).Length() < 1500) clutter.Add(c); } } } } while (currentPos != pos2 && ((currentPos - pos1).Length() < 1500)) { Rectangle position = new Rectangle((int)currentPos.X, (int)currentPos.Y, 0, 0); foreach (ClutterObject c in clutter) { if (position.Intersects(c.GetRectangle())) return false; } currentPos += perMove; } return true; } I'm sure that there's a better way to do this (or at least a way to make this method more efficient), but I'm not too used to XNA yet, so I figured it couldn't hurt to bring it here. At the very least, is there an efficient to determine which objects may be in front of the viewer with greater precision than the rather broad 90 degree window I've given myself?

• Importing PKCS#12 (.p12) files into Firefox From the Command Line

  - by user11165

  I’ve posted this question up on #Ubuntu and #Firefox Forums, and really could do with some help.. Anyone know where i could look or help with the answer. I’m hoping the power of social media will come through… I have a need to perform the following action: Firefox 3.6.x: Quote: open Edit - Preferences - Advanced - Encryption - View Certificates - Your Certificates - Import However i need the same functionality from the bash command line. So far I’ve established that the following command is supposed to be used: Quote: certutil -A -t “u,u,u” -d /home/df001/.mozilla/firefox/qe5y5lht.tc.default/ -n “mycert” -i client.p12 This executes with no isses, however, doesn’t show up in any Firefox Certificate store. However, I have noted that prior to running this command, i have a cert8.db key3.db and secmod.db file in the above folder. After running the command the certutil seems to have created a cert9.db, key4.db and pkcs12.txt file Listing the contents using the command: Quote: certutil -L -d sql:/home/df001/.mozilla/firefox/qe5y5lht.tc.default/ does seem to confirm my attempts of importing files into a certificate folder of some kind have worked. because i get Quote: Certificate Nickname Trust Attributes SSL,S/MIME,JAR/XPI Thawte SSL CA „ Go Daddy Secure Certification Authority „ Thawte SGC CA „ Entrust Certification Authority - L1C „ My Nero CT,C,c mynero P„ davidfield - Internet Widgits Pty Ltd u,u,u So, having tried this, and heading back over to the www, i cam across this command: Quote: pk12util -d /home/df001/.mozilla/firefox/qe5y5lht.tc.default/ -i client.p12 -n “David Field” -P “cert8.db” this again, appears to be importing something somewhere, however, again, Viewing certs from the Firefox interface doesn’t show the imported Cert. I’m surmising here on reading that the certutil and pk12util are creating a new NSS database, which firefox isn’t reading. So my question is, how can i get the p12 cert from the command line so it displays in the firefox Certificate manager interface? Why have i posted this here? Why not post on the firefox forum? Well i will copy and post the same question there as well, however the ability to use the command line to do this is important, as I have potentially 2000 machines which will need a user cert imported into firefox via a p12 file. I need to do this in the form of a script, i thought the hard part was going to be making the p12 file from the microsoft 2003 CA, turns out thats easy. I can’t just import via the GUI and copy over cert8.db x 2000, i can’t ask users to use the CA webinterface as its for VPN access, the users are off site, and they need the VPN to get to the cert server.. Is there any person out there who can help? By the way, i don't have the tor buttun installed.

• Bluetooth from the command line in 12.04?

  - by azzid

  I've been trying to pair up my bluetooth keyboard with my computer after reinstalling from a standard ubuntu 12.04 to a minimal install. In the minimal install I have no gui, so I've been trying to use the various command line tools available, but I can't figure out how the pairing is supposed to go. Pairing when I had a gui worked flawlessly. I've asked for help here: http://ubuntuforums.org/showthread.php?p=12234695 No one has replied but a lot of details of my situation is available there. How is one supposed to pair bluetooth devices from the command line?

• Changing in pavucontrols tab "Recording" via command line

  - by Mojo

  I'm using pavucontrol to make changes in the "Recording". I'm changing the source (??) of a Loopback to Null-Output from "Internes Audio Analog Stereo" to "Monitor of Internes Audio Analog Stereo" see the screenshot http://picpaste.de/Bildschirmfoto_vom_2013-10-26_11_32_03-z0KwnFDE.png I'm now looking for a possibility to do this via command line. So far I've done the following: pactl load-module module-null-sink ? creates a new sink pactl load-module module-loopback ? creates a new sink input pactl load-module module-loopback ? creates another sink input pacmd move-sink-input 0 1 ? changes the sink of the sink-input (to Null-Output); this is like changing manually in the pacucontrol tab "Playback". It's just the last part (making the change like shown in the screenshot) via command line that I'm not able to do. I'd be very happy for any advice or suggestions. Thanks already!

• using ubuntu command line to replace text in huge file

  - by user299331

  hi i have a huge xml file that i must work with. right now the file is only 1 line that contains about 2 million characters which represent 30,000 records. there are no carriage returns or linefeeds whatsoever. what i need to do is make each record on its own line. new records begin with "" and end with "". i've been looking around here and it seems the tools to use are: sed, tr or awk but i'm not sure which is most appropriate. i've tried this to no avail: tr '<ROW' '\012 <ROW' <source.xml |tee destination.xml above seems to output some pretty weird stuff so i must be way off here. maybe its that "<" character that is the problem?

They are displayed with the following code: JPanel myPanel = new JPanel(); myPanel.setLayout(new BoxLayout(myPanel, BoxLayout.Y_AXIS)); JButton button = new JButton("My Button"); JLabel label = new JLabel("My label!!!!!!!!!!!"); myPanel.add(button); myPanel.add(label); I would like to put a horizontal line between my elements (something like <hr> in html). Does anybody know how it can be done?

• Use Network-Manager to Connect to a wifi Access Point on the command-line

  - by Stefano Palazzo

  I'd like to connect to a wireless access point from the command-line. ideally, I'd only need the name of the AP. But the hardware-address would work as well. I know I can use nmcli to connect to a managed network connection, but in my case, the access point may not be configured for Network-Manager yet (See the difference between the output of nm-tool and nmcli con). Example output of nmcli: Auto pwln 3a3d62b1-bbdf-4f76-b4d2-c211fd5cfb03 802-11-wireless [...] Wired Network aa586921-accf-4932-98c4-c873c310f08e 802-3-ethernet [...] Cisco-UDP Uni 7f94847b-04dc-40b7-9955-5246fb77cc65 vpn [...] T-mobile (D1) 867f345a-cbbf-4bd4-b883-a5e5ae0932f0 gsm [...] Example output of nm-tool: State: connected - Device: eth1 [Auto pwln] ---------------------------------------------------- [...] Wireless Access Points (* = current AP) *pwln: Infra, [...], Freq 2472 MHz, Rate 54 Mb/s, Strength 80 WPA WPA2 WLAN: Infra, [...], Freq 2422 MHz, Rate 54 Mb/s, Strength 20 WPA WPA2 [...] How do I connect to an access point that may or may not be known to NM? Extra: Finding out if the connection needs a pass-phrase, and submitting it on the command-line as well would be great too (that is to say It'd be nice if network-manager wouldn't pop open any keyring dialogues or errors on the gui)

• Launching php script through comman line - keeping terminal window open after execution

  - by somethis

  Oh, my girlfriend really likes it when I launch php scripts! There's something special about them, she says ... Thus, I coded this script to run throught the CLI (Command Line Interface) - so it's running locally, not on a web server. It launches just fine through right click open run in terminal but closes right after execution. **Is there a way to keep the terminal window open? Of course I can launch it through a terminal window - which would stay open - but I'm looking for a one click action. With bash scripts I use $SHELL but that didn't work (see code below). So far, the only thing I came up with is sleep(10); which gives me 10 seconds for my girl to check the output. I'd rather close the terminal window manually, though. #!/usr/bin/php -q <?php echo "Hello World \n"; # wait before closing terminal window sleep(10); # the following line doesn't work $SHELL; ?> (PHP 5.4.6-1ubuntu1.2 (cli) (built: Mar 11 2013 14:57:54) Copyright (c) 1997-2012 The PHP Group Zend Engine v2.4.0, Copyright (c) 1998-2012 Zend Technologies )

• Connecting to wireless networks from command line

  - by Balaji

  I need to write a shell script which connects to one of the two available wi-fi connections. One is a un secure connection and the other is secure connection. My question has 2 parts- 1.How to connect to the un-secure (un-encrypted and no password required) connection from command line (or by executing a shell script) when I'm connected to the secure connection? I followed the steps in http://www.ubuntugeek.com/how-to-troubleshoot-wireless-network-connection-in-ubuntu.html for in-secure connection. I put all the commands in a script and executed it (I made sure that interface name and essid are correct) - sudo dhclient -r wlan0 - sudo ifconfig wlan0 up - sudo iwconfig wlan0 essid "UAPublic" - sudo iwconfig wlan0 mode Managed - sudo dhclient wlan0 But nothing happens - I'm not disconnected from the current network and connected to the new one 2.When I want to connect to the secure wi-fi network, I understand from http://askubuntu.com/a/138476/70665 that I need to use wpa_supplicant. But I enter a lot of details in the interface when I connect via UI security : wpa and wpa2 enterprise Authentication : PEAP CA certificate : Equifax... PEAP version : automatic inner authentication : MSCHAPv2 username : password : How to use wpa_supplicant to mention all these details in the command line? The conf file network={ ssid="ssid_name" psk="password" } doesn't work for me.

• How to Print or Save a Directory Listing to a File

  - by Lori Kaufman

  Printing a directory listing is something you may not do often, but when you need to print a listing of a directory with a lot of files in it, you would rather not manually type the filenames. You may want to print a directory listing of your videos, music, ebooks, or other media. Or, someone at work may ask you for a list of test case files you have created for the software you’re developing, or a list of chapter files for the user guide, etc. If the list of files is small, writing it down or manually typing it out is not a problem. However, if you have a lot of files, automatically creating a directory listing would get the task done quickly and easily. This article shows you how to write a directory listing to a file using the command line and how to use a free tool to print or save a directory listing in Windows Explorer.

• Create USB installer from the command line?

  - by j-g-faustus

  I'm trying to create a bootable USB image to install Ubuntu on a new computer. I have done this before following the "create USB drive" instructions for Ubuntu desktop, but I don't have an Ubuntu desktop available. How can I do the same using only the command line? Things I've tried: Create bootable USB on Mac OS X following the ubuntu.com "create USB drive" instructions for Mac: Doesn't boot. usb-creator: According to apt-cache search usb-creator and Wikipedia usb-creator only exists as a graphical tool. "Create manually" instructions at help.ubuntu.com: None of the files and directories described (e.g. casper, filesystem.manifest, menu.lst) exist in the ISO image, and I don't know what has replaced them. unetbootin scripting: Requires X server (graphics support) to run, even when fully scripted. (The command sudo unetbootin lang=en method=diskimage isofile=~/ubuntu-10.10-server-amd64.iso installtype=USB targetdrive=/dev/sdg1 autoinstall=yes gives an error message unetbootin: cannot connect to X server.) Update Also tried GRUB fiddling: Merging information from pendrivelinux.com a related question on the Linux Stackexchange and a grub configuration example I was able to get halfway there - it booted from USB, displayed the grub menu and started the installation, but installation did not complete. For reference, this is the closest I got: sudo su # mount USB pen mount /dev/sd[X]1 /media/usb # install GRUB grub-install --force --no-floppy --root-directory=/media/usb /dev/sd[X] # copy ISO image to USB cp ~/ubuntu-10.10-server-amd64.iso /media/usb # mount ISO image, copy existing grub.cfg mount ~/ubuntu-10.10-server-amd64.iso /media/iso/ -o loop cp /media/iso/boot/grub/grub.cfg /media/usb/boot/grub/ I then edited /media/usb/boot/grub.cfg to add an .iso loopback, example grub entry: menuentry "Install Ubuntu Server" { set gfxpayload=keep loopback loop /ubuntu-10.10-server-amd64.iso linux (loop)/install/vmlinuz file=(loop)/preseed/ubuntu-server.seed iso-scan/filename=/ubuntu-10.10-server-amd64.iso quiet -- initrd (loop)/install/initrd.gz } When booting from USB, this would give me the Grub boot menu and start the installer, but the installer gave up after a couple of screens complaining that it couldn't find the CD-ROM drive. (Naturally, as the box I'm installing on doesn't have an optical drive.) I resolved this particular issue by giving up and doing the "create USB drive" routine using the Ubuntu Live desktop CD (on a computer that does have an optical drive), then the USB install works. But I expect that there is some way to do this from the command line of an Ubuntu system without X server and without an optical drive, so the question still stands. Does anyone know how?

• best command line tool to join videos

  I have used ffmpeg, but with it you have to first make mpg videos then do cat video1.mpg video2.mpg > joined.mpg and then convert to joined.mpg to joined.mp4 with ffmpeg to be able to upload on youtube. I heard there's mencoder which can join avi files without converting to mpg and using cat command. I'm making videos to upload on youtube so it needs to be avi mp4 or flv format. Which tool is the best to join videos from command line?

• Websites with horizontal accordion effect

  - by peterdp

  Hi Folks, I was delighted with the responses folks offered to the question about horizontal sliding panels that I thought I would try again. In subsequent discussions with my colleagues, it became clearer that we would also like to consider horizontal accordion effects, so I am looking for some concrete, real world examples. Soo... I would once again be most grateful to the stalwart StackOverflowians who could take a moment to paste links to their favorite website(s) that use a horizontal accordion effect well. Extra kudos if you can promote your own site! Thanks so very much if you can help!
