  • modify the way files get opened from finder by shift-clicking (etc) as in windows

    - by stib
    In the windows shell it is possible to modify the default action for opening any document type when holding down a modifier key such as shift or option when double clicking. So for example I can open a jpeg in irfanview if I just double click it, in firefox if I shift-double click it or in potatoshop if I option-double click it. However on a mac I have to right click, and choose "open with..", which can be annoying when there are a lot of possible candidates (such as with jpegs) or if I want to open the file with somehting like an applescript, which won't show up on the list and will have to be found in the file system and specified manually, every.. single.. time. Is there a way of making the mac open files differently by holding down modifier keys when double clicking?

  • Adding a trigger command to autocomplete function in zsh

    - by mkaito
    When you define an alias like alias g=git, the shell will pick it up and run the corresponding autocomplete function. Now, there's a program out there called hub, which is basically a supserset of git, with some added, github-specific functionality. The recommended way to use hub is to alias git=hub. Of course, this won't trigger the autocomplete function for git, which makes sense. Now, if I wanted to have git's autocomplete trigger for hub, the only way I know of is editing /usr/share/zsh/functions/Completion/Unix/_git and adding hub in the first line as trigger. While this works, it isn't practical, since this file will get overwritten with the next zsh release. Assuming hub won't provide a zsh completion function any time soon, is there another way of adding hub to the trigger commands for git's autocomplete function?

  • Can I make ssh tell me which control file it would use for multiplexing?

    - by Ryan Thompson
    I am using the following options in my ~/.ssh/config in order to enable connection multiplexing: ControlMaster auto ControlPath ~/.ssh/control/master-%r@%h:%p However, this has the annoying problem that the first shell to connect to a particular server must be the last to disconnect, because it is the master connection that all the other connections are using. So if you log out of the master, it appears to just hang. To solve this, I would like to wrap ssh with a script that checks if the control master file exists, and if not, starts a master ssh process in the background. Then it would start a slave ssh session. In order to accomplish this, my script would have to determine the path to the control file that ssh would use. This would entail parsing the ssh command line options and config files and implementing the logic for determining the ControlPath. Is there any way to just ask ssh what path it would use, so I can check it?

  • Using physical disk with VMware Workstation

    - by chx
    I am using VMware Workstation 9.0 under Windows 7 and trying to load my Linux from Physicaldisk0. And it boots, grub sees the two partitions on the disk (I checked in command line) and the kernel and the initrd loads and then it stops saying "device not found"and drops me into an emergency shell. Indeed there is absolutely nothing in /dev not the /sda device it expects not /hda nothing that looks like a disk. Edit: I can boot the Linux disk just fine if I boot it from BIOS and not as a VM. Edit2: The question is, how can I make this setup work?

  • chmod -R 777 /. - RHEL 5.5

    - by user1263746
    A shell script testing went bad and it issued chmod -R 777 /. to the system, instead of chmod -R 777 ./ and as expected it wiped the critical meta data. We have turned off the system and it will not function properly the next time it is turned on. I am told that rpm --setperms -a rpm --setugids -a should atleast fix the permission of the packages maintained by rpm. Is it worth doing? And is there any script available which will copy the permission from an identical system? To atleast get the box working. The Box is running RHEL5.5 Thanks!

  • Showing protocol specific mini icons for Jabber/XMPP gateway contacts

    - by aef
    Since a short while I'm using Ubuntu Oneiric Ocelot (11.10) with gnome-shell (Gnome 3) and I'm trying to get accustomed to the default Empathy Instant Messaging client. I'm using a gateway service on the side of my Jabber/XMPP server to communicate with lots of contacts over proprietary networks like ICQ or MSN. So I don't use Empathy's native support for ICQ and MSN, and I don't want to change back to using such a thing for various reasons. One thing that annoys me is that Empathy does not make it clear to me that these contacts are from another instant messaging network. If I enable the View Show Protocols option they are all recognized as Jabber/XMPP contacts. Although I perfectly understand why that happens, I would like to be able to change this behavior to make Empathy mark these contacts correctly. Is there a configuration option or a plugin for this? Or may this feature still be in development and will be available later?

  • On Windows, what filename extensions denote an executable?

    - by Ken
    On Windows, *.exe, *.bat, *.cmd, and *.com all represent programs or shell scripts that can be run, simply by double-clicking them. Are there any other filename extensions that indicate a file is executable? EDIT: When I jump into a new project (or back into an old project!), one of the common things I want to do when looking around is to find out what tools there are. On Unix (which I've used for decades), there's an execute bit, so this is as simple as: find . -executable -type f I figured that on Windows, which seems to have a much more complex mechanism for "is this executable (and how do I execute it)", there would be a relatively small number of file name extensions which would serve roughly the same purpose. For my current project, *.exe *.bat *.cmd is almost certainly sufficient, but I figured I'd ask if there was an authoritative list.

  • Linux file permissions not being preserved

    - by yellavon
    I am deploying some custom software as root (a necessity for this situation). I set the owner/group to user1:user1 and set all the files to 644 beforehand in shell, then copy and deploy with ant. However, when files get copied over from the deployment directory, the ownership changes back to root and all the files install with 666 permissions. This seems to occur whether the file is overwritten or newly created. I believe there is a way to set an option in cp, mv commands to preserve permissions, but that would be a lot of commands to change. How can I fix this? Is there some setting I can change temporarily for root so the install always preserves the file permissions?

  • How to get rid of diacritics on my keyboard?

    - by stevenvh
    I searched Google and SU for my problem, but everybody seems to want to add diacritics, while I don't want them. I'm using Windows 7 and have a US keyboard installed, not the international version. Despite that some keys, like ", ^ and ~ are used for diacritics, which means that I have to type "SPACE to get a double quote. How do I get rid of this? My other PC, with the same settings, doesn't show this behavior. edit re Stefan's answer I don't see the icon Stefan refers to in my taskbar, probably because I have Classic Shell installed. But this is a screenshot of the Input Languages dialog, there are no other keyboards installed:

  • Why is it bad to map network drives in Windows?

    - by Beeblebrox
    There has been some spirited discussion within our IT department about mapping network drives. In particular, it has been said that mapping network drives is A Bad Thing and that adding DFS paths or network shares to your (Windows Explorer/Libraries) Favourites is a far better solution. Why is this the case? Personally I find the convenience of z:\folder to be better than \\server\path\folder', particularly with cmd line and scripting (of course I'm not talking about hard-coded links, naturally!). I have tried searching for pros and cons of mapped network drives, but I haven't seen anything other than 'should the network go down, the drive will be unavailable'. But this is a limitation of any network-accessed storage... I have also been told that mapped network drives poll the network when the network resource is unavailable, however I haven't found more information on this. Wouldn't this still be an issue with other network access mechanisms (that is, mapped Favourites) whenever Windows tries to enumerate the file system (for example, when a file/folder picker dialog is opened)? -- Do network drives poll the network any more than a Windows Explorer library/favourite?

  • Is there a difference between starting a WebLogic Admin Server through the command-line or through t

    - by lindelof
    I have WebLogic 11g installed on my machine under /srv/wls, and I start Node manager on it with /srv/wls/wlserver_10.3/server/bin/startNodeManager.sh. I create my domain with config.sh, and then I want to start the Admin Server of that domain with Node Manager. So I open a WLST session and do the following: > nmConnect(...) > nmStart('AdminServer') But when I then visit localhost:7001/console, and login, the screen on the browser remains blank and the server logs tell me the server has run out of PermGen space. I don't encounter this problem when starting the Admin Server through the shell script under $DOMAIN/startWebLogic.sh. Then it works fine. Any idea what I am doing wrong? I couldn't find anything in Google nor on the Oracle forums...

  • How to troubleshoot a remote wmi query/access failure?

    - by Roman
    I'm using Powershell to query a remote computer in a domain for a wmi object, eg: "gwmi -computer test -class win32_bios". I get this error message: Value does not fall within the expected range Executing the query local under the same user works fine. It seems to happen on both windows 2003 and also 2008 systems. The user that runs the shell has admin rights on the local and remote server. I checked wmi and dcom permissions as far as I know how to do this, they seem to be the same on a server where it works, and another where it does not. I think it is not a network issue, all ports are open that are needed, and it also happens within the same subnet. When sniffing the traffic we see the following errors: RPC: c/o Alter Cont Resp: Call=0x2 Assoc Grp=0x4E4E Xmit=0x16D0 Recv=0x16D0 Warning: GssAPIMechanism is not found, either caused by not reassembled, conversation off or filtering. And an errormessage from Kerberos: Kerberos: KRB_ERROR - KDC_ERR_BADOPTION (13) The option code in the packet is 0x40830000 Any idea what I should look into?

  • Determine if the "yes" is necessary when doing an SCP

    - by glowcoder
    I'm writing a Groovy script to do an SCP. Note that I haven't ran it yet, because the rest of it isn't finished. Now, if you're doing an scp for the first time, have to authenticate the fingerprint. Future times, you don't. My current solution is, because I get 3 tries for the password, and I really only need 1 (it's not like the script will mistype the password... if it's wrong, it's wrong!) is to pipe in "yes" as the first password attempt. This way, it will accept the fingerprint if necessary, and use the correct password as the first attempt. If it didn't need it, it puts yes as the first attempt and the correct as the second. However, I feel this is not a very robust solution, and I know if I were a customer I would not like seeing "incorrect password" in my output. Especially if it fails for another reason, it would be an incredibly annoying misnomer. What follows is the appropriate section of the script in question. I am open to any tactics that involve using scp (or accomplishing the file transfer) in a different way. I just want to get the job done. I'm even open to shell scripting, although I'm not the best at it. def command = [] command.add('scp') command.add(srcusername + '@' + srcrepo + ':' + srcpath) command.add(tarusername + '@' + tarrepo + ':' + tarpath) def process = command.execute() process.consumeOutput(out) process << "yes" << LS << tarpassword << LS process << "yes" << LS << srcpassword << LS process.waitfor() Thanks so much, glowcoder

  • How to organise storage for media content such as video and music?

    - by thor
    Currently, we have a single server hosting all content: music, video and software. This content is downloaded by users through HTTP. Now free space is coming to an end and we are exploring different ways of extending our storage capacity. We want to do it cheap, simple and reliable (protected from disk/ server faults). Currenly, we see two ways: Add a couple of cheap servers with 4 disks (RAID1 ?), run some distributed file-system on top, like GlusterFS. Pros: hopefully, we will see all our disks as single flat file system, just dump content into it and be done. Cons: could be tricky in configuration and handling of faults. Add a couple of cheap servers, all running HTTP servers. Each piece of content (be it a music file or video) is placed on randomly selected two servers. Pros: don't have to deal with RAID, as content is duplicated; single server failure does not bring down any part of content; doubled distribution capacity (as any signle file could be downloaded from any of two servers hosting it). Cons: requires some scripting on part of distribution of content, adding/ removing servers. Do we miss any other ways? Which of the aforementioned options seems to be the best?

    So, this Ubuntu software center comes with 100s of applications of all types. In this version they have disabled rating, making it hard to find how good it is. I found gnome-shell today, that seemed awesome. There are other ones, less well known, For eg, Abiword is far better than Open Office Org Word processor in many ways. (Altho' I dont like word processors themselves.) What are the other less well known applications that you use and like. One application per answer.

  • Is it possible to use SELinux MCS permissions with Samba?

  • How do I open a pdf file with PDF X-Change Viewer so that I can still modify the pdf source?

    - by ltcomdata
    Whenever I open a pdf file with PDF X-Change Viewer it locks up the source pdf file to edits. Is there a way to open the pdf (with PDF X-Change Viewer) so that it doesn't lock-up the source file --- perhaps as a shell command with an option? The background: I use LaTeX to edit my pdf files, and preview the result with PDF X-Change Viewer. I must first close PDF X-Change Viewer before I can preview any changes I make in the LaTeX source. It would be nice if PDF X-Change Viewer did not lock-up the pdf source so that I could modify it without first closing PDF X-Change Viewer.

  • pip install very slow through virtual box

    - by AJP
    pip install --exists-action=w -r requirements.txt is very very slow through virtual box. Any suggests of how to diagnose and fix? Would seeing the VagrantFile be useful? VirtualBox 4.2.12 (can't upgrade to .14 as it doesn't work.) Vagrant 1.0.7 Host machine: ProductName: Mac OS X ProductVersion: 10.7.5 BuildVersion: 11G63b VagrantFile contains: Vagrant::Config.run do |config| config.vm.box = "precise64" config.vm.customize ["modifyvm", :id, "--memory", 2048] config.vm.box_url = "http://files.vagrantup.com/precise64.box" config.vm.network :hostonly, "33.33.33.21" config.vm.forward_port 5000, 5000 config.vm.forward_port 5555, 5555 config.vm.share_folder "v-root", "/vagrant", "./" Vagrant::Config.run do |config| config.vm.provision :shell, :inline => "VENV=/usr/local/venv bash /vagrant/setup_env.sh" end end Normal download speed is only about 5 times slower at 0.8 Mb per second versus 4 MB per second (as judged by curling a 50 Mb file from S3). But pip install is taking about 20 times longer from Mac (i.e. about 40 minutes) versus 2.

  • Secure Apache Virtual Hosts?

    - by Dr Hydralisk
    I am going to host a few small sites on VPS, and each of them are going to run my own custom PHP scripts. I am fairly certain that they are secure (did everything in the book, plus some of which is not in the book) to make sure they can't be exploited. But just to be safe I want to know how I could secure each of the virtual hosts so that they can't escape from there virtual host (if a hacker uploaded a shell they could not go above the www folder a legitimate user can't do in ftp no matter how many times they click ..) folder on Debian and Apache.

  • Ctrl W s not splitting windows in vim

    - by rajan sthapit
    I am trying to use Ctrl+ws to split a window in vim. However it is not working in my case. I opened a file using vim filename. Then I pressed Ctrl+ws. But as soon as I press just Ctrl+w it clears the viewport and I could see my shell display before vim opened the file. I mean the view port is replaced by the content just before the file was opened. However, I am still editing the file with vim. Suggestions?

  • IRC "proxy" for persistent connection between several computers

    - by Zeta Two
    I'm looking for a program that enables me to stay connected to one or more IRC networks and be able to view the log even though I connect from several different computers. I'm thinking about something like a proxy running on a server who always is connected to the servers/channels I want and to which I connect from whichever client I want to use. Does anyone know of a program like this? Edit: Apparently I could be running a IRC session in a shell on a server and connect to this but I would like something more GUI:ish.

  • How to repair unbootable Fedora install

    - by Cerin
    How do you repair/reinstall Fedora without deleting any existing partitions or data? I was attempting to upgrade some old Fedora 13 servers to 17, following the instructions in the wiki. After the 14-15 upgrade, rebooting resulted in the output: Dropping to debug shell. sh: can't access tty; job control turned off dracut:/# Running dmesg also shows: dracut Warning: No root device "block:/dev/mapper/VolGroup-lv_root" found Googling shows this error is typically related to some weird RAID issues, but my server is a virtual machine not using any RAID. Using a rescue CD, I can chroot /mnt/sysimage, and all packages and data still seems to be there. How do I make the system bootable again?

  • How do I reattach to Ubuntu Server's 'do-release-upgrade' process?

    - by Alex Leach
    I accidentally pressed Ctrl+C during Ubuntu Server's do-release-upgrade process. I'd dropped to a shell to compare a .conf file in /etc/. When I pressed Ctrl-C, it asked whether I wanted to try to reattach to the upgrade process, but it failed to do so. So I quit, and now there's a hanging dpkg process which is holding onto the apt lock. This is a virtualised server with no GUI frontend... Is it possible to recover the upgrade process, or do I have to kill the dpkg process and start again? UPDATE:- AFAICT, there was no way to reattach to the upgrade process. However, it wasn't a disaster at all. I killed the hanging dpkg process, and then ran dpkg --configure -a. This walks you through reconfiguring all packages already installed on the system, tidying up any problems whilst it does so. After that, I used aptitude to upgrade the remaining packages, which had already been downloaded, but hadn't been installed or configured.
