• What's the command to open the Unity Dash?

  - by Scintoon

  I would like to know the command (from the Terminal) which opens the Unity dash, the reason being I want to create a desktop icon that starts the dash instead of the 'Windows Key' for keyboard-free use of the computer (I miss the old Ubuntu-Tweak effect where putting your mouse to the corner of the desktop would reveal Expo or Scale effects - by the way, is it possible to get it back?) Making a launcher (Application, Name, Command, Comment, etc) I tried the commands 'Unity', 'Dash' and other things, but I didn't manage to get it to work. I am using version 12.04

• 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?

• best command line tool to join videos

  - by user1079002

  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?

• How can I pass more than one command line argument via c#

  - by user293392

  I need to pass more than one command line argument via c# for a process called handle.exe: http://www.google.com.mt/search?sourceid=chrome&ie=UTF-8&q=handle.exe First, I need to run the executable file via ADMINISTRATOR permissions. This post has helped me achieve just that: http://stackoverflow.com/questions/667381/programatically-run-cmd-exe-as-adminstrator-in-vista-c But then comes the next problem of calling the actual line arguments such as "-p explore" How can I specify the command line arguments together, or maybe consecutively? Current code is as follows: Process p = new Process(); ProcessStartInfo processStartInfo = new ProcessStartInfo("filePath"); processStartInfo.CreateNoWindow = true; processStartInfo.UseShellExecute = false; processStartInfo.RedirectStandardOutput = true; processStartInfo.RedirectStandardInput = true; processStartInfo.Verb = "runas"; processStartInfo.Arguments = "/env /user:" + "Administrator" + " cmd"; p.StartInfo = processStartInfo; p.Start(); string output = p.StandardOutput.ReadToEnd(); p.WaitForExit(); Console.WriteLine(output); Thanks

• Default Transaction Timeout

  - by MattH

  I used to set Transaction timeouts by using TransactionOptions.Timeout, but have decided for ease of maintenance to use the config approach: <system.transactions> <defaultSettings timeout="00:01:00" /> </system.transactions> Of course, after putting this in, I wanted to test it was working, so reduced the timeout to 5 seconds, then ran a test that lasted longer than this - but the transaction does not appear to abort! If I adjust the test to set TransactionOptions.Timeout to 5 seconds, the test works as expected After Investigating I think the problem appears to relate to TransactionOptions.Timeout, even though I'm no longer using it. I still need to use TransactionOptions so I can set IsolationLevel, but I no longer set the Timeout value, if I look at this object after I create it, the timeout value is 00:00:00, which equates to infinity. Does this mean my value set in the config file is being ignored? To summarise: Is it impossible to mix the config setting, and use of TransactionOptions If not, is there any way to extract the config setting at runtime, and use this to set the Timeout property [Edit] OR Set the default isolation-level without using TransactionOptions

• 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?

• Select (loop) or command not working in shell-script

  - by user208098

  I've been tinkering with Linux and Unix for years but still a novice in my mind and recently find myself trying to be more pro with it as I work in IT. So with that notion I'm studying shell scripting. I've hit a snag in ubuntu using the latest version 13.10 Saucy. When I use the select command in a sh script it doesn't work, depending on how I format the command it will either return Unexpected "do" or Unexpected "done". See the following two examples: This section of code produces an unexpected "do" error: #/bin/bash PS3='Please enter your choice' select opt in option1 option2 option3 quit do case $opt in "option1") echo "you chose choice 1" ;; "option2") echo "you chose choice 2" ;; "option3") echo "you chose choice 3" ;; "quit") break ;; *) echo invalid option ;; esac done This section of code produces an unexpected "done" error. #/bin/bash PS3='Please enter your choice' select opt in option1 option2 option3 quit ; do case $opt in "Option1") echo "you chose choice 1" ;; "Option2") echo "you chose choice 2" ;; "Option3") echo "you chose choice 3" ;; "quit") break ;; *) echo invalid option ;; esac done When I enter these parameters into the command line interactively or manually I get the desired result which is a list of choices to choose from. However when executed from a script I get the before mentioned errors. Also a side note I have tried this in Fedora as a script and it worked perfectly so my question is why isn't it working in Ubuntu, is this a difference between RHL and Debian? Or is it a bug in the latest version of Ubuntu? Thanks in advance for any help! KG

• 4.4.1 Timeout in 10 minute intervals SMTP on batch email jobs

  - by TEEKAY

  I am running a job that uses SMTP and it can run in excess of an hour, emailing the entire time. It's not my code but a workflow based app so I just get a form to configure the mail server, subj, msg, etc and can't see it's implementation. I know it is .NET and SmtpClient. I have been seeing 4.4.1 timeouts every 10 minutes being reported by the application as the response from the server. The # of emails in those 10 minute sessions are variable, between 100 and below 150 which leads me to ask about the 10 minute timeout time specifically. I have found there are several exchange properties (though I don't know what version they are running) that set timeout limits. (http://technet.microsoft.com/en-us/library/bb232205%28v=exchg.150%29.aspx) Would those values for ConnectionInactivityTimeOut and ConnectionTimeout be the controlling the timeouts? and finally I would like to ask if exchange considers the consistent connection(s) it kept receiving from the same source as one continuous connection and cause the timeout each 10 minutes and cause the timeout? I am using a static ip of the mail server. Thanks if anyone can shed any light on my problem. EDIT - It is my belief that the library is just keeping the connections around and isn't wrapped in any cleanup code or using statement. That said, I still haven't made any progress on this issue in the last year and just requeue the failed ones as I see them.

• Using ssh for remote command

  - by user1663479

  I need to use ssh to execute a remote command such as: ssh -l jsilva xman /vol/2011/linux_x64/exe/mx201111.exe When I execute ssh I receive error message: /cmg/2011.11/linux_x64/exe/mx201111.exe: error while loading shared libraries: libmkl_intel_lp64.so: cannot open shared object file: No such file or directory This application uses the variable LD_LIBRARY_PATH. I inserted this variable into /etc/profiles in localhost and remote host. The filesystem /cmg is mounted by autofs for both hosts (local and remote). Anybody have idea how to resolve this problem? Thanks!

• SQL Server Reporting Services proxy timeout (ASP.NET)

  - by Philip

  Morning, We are using SSRS (2005) and have a ASP.NET frontend using the SSRS WebControl. I've boiled the problem down the time it takes for one particular report to be generated is greater than the timeout on the proxy server. It looks like the way the SSRS web control tries to do things is by performing an HTTP request for the report, however the problem with this is the request can timeout potentially before the report has generated. Looking at the HTTP traffic the response is a 504 (gateway timeout). Is there a way to increase the timeout or change SSRS WebControl to use more robust polling mechanism (which isn't dependant on the timeout of the HTTP request). I could be wrong but I don't think ServerReport.Timeout property would resolve the issue we are seeing? Any thoughts? Philip

• Accessibility bus warning when opening files in Eclipse from command line (Ubuntu 13.10)

  - by Reese

  Similar to closed issue Gnome Menu Broken? When opening a file from the command line for edits in Eclipse , I get this warning: ** (eclipse:nnnn): WARNING **: Couldn't register with accessibility bus: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. The 4-digit number at (eclipse:nnnn) changes each time I issue an 'eclipse some/file.ext' command. The file opens but the warning is an annoyance that shouldn't be happening, it may be indicative of some other problem. Updated Ubuntu 13.10 64-bit, updated Eclipse Luna.

• 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?

• cd command not working anymore

  - by dystroy

  I just did two things : install scm_breeze and mercurial : git clone git://github.com/ndbroadbent/scm_breeze.git ~/.scm_breeze ~/.scm_breeze/install.sh sudo apt-get install mercurial And now my cd command seems to be gone : dys@dys-tour:~/prog> cd ~ bash: /home/dys : is a folder dys@dys-tour:~/prog> cd .. .. : command not found The terminals I opened before installing scm_breeze and mercurial are fine. The terminals I open now have the problem. I uninstalled scm_breeze, with no result. What can I do to diagnose the problem and fix it ?

• How to set timeout with python-mechanize?

  - by Michal Cihar

  I'm using python-mechanize to scrape some web sites, which sometime simply don't respond to requests and these requests stay open too long, so I need to limit timeout for these requests. While using urlopen method, the timeout can be set using timeout parameter, but I have not found easy way for doing it with high level API such as submit or click methods. Ideally the timeout would be set just once for whole browser class and all calls would honor that. It would be probably possible to customize this by passing custom request_class to every click and submit call, but this would just pollute the code, so I'm looking for nicer solution for setting timeout for mechanize's browser class (and no, I don't want to change default socket timeout using socket.setdefaulttimeout).

• 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!

• 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?

• "find" command and piping its output through another program

  - by Charbel

  this is not an Ubuntu specific quesion, it applies to all unix/linux. how can I run a command like this: find . -maxdepth 1 -type d -print -exec svn info "{}" | grep URL \; the command above doesn't do what I want, I can't seem to pipe the output of the svn info to grep. This works, but the output contains much more than I need: find . -maxdepth 1 -type d -print -exec svn info "{}" \; Any ideas?

• Can I use a wildcard to denote subdirectories as opposed to just files in the Windows Command Prompt

  - by Dinosaurus

  I know I can use a wildcard to list the files in a single directory: dir *.java However, does anyone know if it is possible to denote a subdirectory with a wildcard as well? I would like to do something like dir classes/*/*.java Where, it will list all the java files in every subdirectory beneath the classes directory. So, if there is: classes/cs1100/ classes/cs1200/ classes/cs1500/ It will list all the java files within these. Note, I'm not using this specifically for the "Dir" command, but instead another command line tool that accepts a list of files. But, if it works for Dir, it shoudl work in my other program as well.

• ssh timeout when connecting to ec2 instances

  - by Johnny Wong

  After there has been a timeout on my ssh connection (e.g., left the ssh session running and closed my laptop), it is very difficult to re-login with ssh. I keep getting an ssh timeout error. I tried removing the hostname from the known_host file (per a friend's suggestion) which sometimes helps, but other times doesn't -- and I dont know why This is in connection to accessing my EC2 instance on Amazon. This is driving me nuts -- any help, much appreciated.

• Command-Line Parsing API from TestAPI library - Type-Safe Commands how to

  - by MicMit

  Library at http://testapi.codeplex.com/ Excerpt of usage from http://blogs.msdn.com/ivo_manolov/archive/2008/12/17/9230331.aspx A third common approach is forming strongly-typed commands from the command-line parameters. This is common for cases when the command-line looks as follows: some-exe COMMAND parameters-to-the-command The parsing in this case is a little bit more involved: Create one class for every supported command, which derives from the Command abstract base class and implements an expected Execute method. Pass an expected command along with the command-line arguments to CommandLineParser.ParseCommand – the method will return a strongly-typed Command instance that can be Execute()-d. // EXAMPLE #3: // Sample for parsing the following command-line: // Test.exe run /runId=10 /verbose // In this particular case we have an actual command on the command-line (“run”), which we want to effectively de-serialize and execute. public class RunCommand : Command { bool? Verbose { get; set; } int? RunId { get; set; } public override void Execute() { // Implement your "run" execution logic here. } } Command c = new RunCommand(); CommandLineParser.ParseArguments(c, args); c.Execute(); ============================ I don't get if we instantiate specific class before parsing arguments , what's the point of command line argument "run" which is very first one. I thought the idea was to instantiate and execute command/class based on a command line parameter ( "run" parameter becomes instance RunCommand class, "walk" becomes WalkCommand class and so on ). Can it be done with the latest version ?

• Determining timeout reason

  - by datatoo

  What is the best way to determine what causes a server timeout on a Plesk passworded directory in IIS6? Even if the default page is static text I can get a timeout. This has worked fine for two years and has only seemed to change after adding a new permitted user. Occasionally there is success but usually loading is very slow. Where would I look for a problem, as it doesn't seem to be page content causing the issue?

• How can I uniqely record every new command I use, and possibly timestamp it?

  - by Nirmik

  I've been on Linux for more than 6 months now but never went too much into the CLI (command-line interface or terminal or shell) Now as I ask questions here, get answers, or help from other sites, I learn new commands... How can I can store every new command in a text file? Only new/*unique* commands, not repetitions of the same command. Here's an example: In the terminal, I enter the commands like this- ubuntu@ubuntu:~$ *command1* ubuntu@ubuntu:~$ *command2* ubuntu@ubuntu:~$ *command3* ubuntu@ubuntu:~$ *command4* ubuntu@ubuntu:~$ *command1* Now, these commands should get saved in a text file say commandrec like this- *command1* *command2* *command3* *command4* NOTE:The last command in the terminal which was again command1 is not recorded/saved again in the text file. And the next time I open the terminal, and enter a new command command 5, it should get appended to the list in commandrec (but if the command was used earlier on some other date, it should still be ignored. For example, command 1 entered again along with command 5 on a new day/time but command1 not recorded as already used) The commandrec file looking something like this- 31/05/12 12:00:00 *command1* *command2* *command3* *command4* 01/06/12 13:00:00 *command 5* (the time and date thing would be great if possible, but okay even if that isn't there) This way, I can have a record of all commands used by me to date. How can this 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)
