  • When using gt5 in my home directory I get a blank page.

    - by MT
    When using gt5 in various directories on my system (including my home directory) I get blank results. If I limit the max-depth enough, I get results. For example, in my home directory 'gt5 --max-depth 2' produces a listing, while 'gt5 --max-depth 3' produces a blank page. I've noticed that the temporary html file that gets created in tmp (such as '/tmp/gt5.9035.kJVM08Y9/gt5.html' is a zero-byte file. I can successfully do a du in the same directory (which is what I thought gt5 was using), so I'm not sure what to check?

  • Kill program after it outputs a given line, from a shell script

    - by Paul
    Background: I am writing a test script for a piece of computational biology software. The software I am testing can take days or even weeks to run, so it has a recover functionality built in, in the case of system crashes or power failures. I am trying to figure out how to test the recovery system. Specifically, I can't figure out a way to "crash" the program in a controlled manner. I was thinking of somehow timing a SIGKILL instruction to run after some amount of time. This is probably not ideal, as the test case isn't guaranteed to run the same speed every time (it runs in a shared environment), so comparing the logs to desired output would be difficult. This software DOES print a line for each section of analysis it completes. Question: I was wondering if there was a good/elegant way (in a shell script) to capture output from a program and then kill the program when a given line/# of lines is output by the program?

  • Sound plays on headphones and speakers with Lenovo ThinkPad L512 + Ubuntu 10

    - by Oscar Godson
    The only thing really missing from this install is this issue with the sound. I've searched all over the forums and i found one thing where you get the model and codecs and write them to a file, however, I can't seem to find what my "model" is because none of the postings have anything about Lenovo laptops. Here is the command they all asked for: Code: cat /proc/asound/card0/codec#* | grep Codec Codec: Realtek ALC269 Codec: Intel G45 DEVIBX With that info, how do I get the model, and how do I get my speakers to stop playing when headphones are plugged in. Also, I don't have any software installed like pulse audio either, so it's not that. Thanks so much to whoever can answer this... The Ubuntu forums are nearly useless... ive never gotten a correct answer back on that site.

  • how to properly edit hosts, hostname and resolf.conf?

    - by Firewall
    i,v been searching the internet for a real noop tutorial on the subject but could not found any direct info. on how to edit these files the proper way. i,v got a debian internet server that i use to host some personal domains and runs squid and rTorrent. the server is up and running with no problems but i am confused about a few things. lets say that i named my server (foo), my domain is (example.com) and my public IP is 95.211.133.200 now: should /etc/hostname contains: tango.example.com or tango <----- just the server name should /etc/hosts contains: 127.0.0.1 localhost.localdomain localhost 95.211.133.200 foo.example.com foo should /etc/resolf.conf contains (along with the nameservers) both: domain example.com search example.com or just the first one. are there any other files that i should edit in order to make things right? last thing, the command: domainname returns: (none) i believe it should return (example.com). what should i do to correct that?

  • grub2 error: out of disk

    - by Carl Smotricz
    I'm trying to make a 250G USB hard disk Ubuntu-bootable on a Compaq nc6220 laptop. I've removed all other disks, so /dev/sda (the USB disk) is the only disk other than CDROM. I installed Ubuntu 9.10 to this disk from the live CD, putting the bootloader on /dev/sda . The default system couldn't be booted, and nothing I did in the Grub menu/cmdline helped. So I chrooted onto the disk and did grub-install /dev/sda. That seemed to work fine, but Grub (1.97 beta 4) keeps coming up with error: out of disk Even when I drop to the command line to do something simple like ls or help, it's always the same error message. Any hints for resolving this, please?

  • How do you enable webcam support in facebook for ubuntu 10.04?

    - by Jonathan
    I think I have finally arrived at an insolvable equation: Chromium v.7 + Ubuntu 10.04 + Sun Java 6 + Webcam + Facebook + Flash 10 = non-functional All of those items listed above are potential points of failure in this situation, and any help narrowing them down would be fantastic. I am simply trying to enable webcame support directly through Facebooks website. Forum searches and the usual googling turn up few posts related to this specific equation. Two of the major suggestions include: 1) Installing the Sun (I refuse to say oracle sob)-provided Java implementation instead of the OpenJDK normally installed in ubuntu. And yes, after installing it, I did update all my default supports to use the sun commands over the openjdk. 2) Somehow enabling Facebook as a permitted site to access my webcam using Flash settings. I have not been able to explore option 2 because I cannot find a way to adjust the Flash settings in chromium 7. Other factors that do not help include the fact that I am pretty sure facebook changes its webcam interface every 10 seconds just to keep troubleshooters and support personnel on their toes. If anyone has a OTP that informs us of the next shift in the app, a leak would be greatly appreciated! Cheers!

  • Gnome, open with, custom command, filename reference

    - by Tergiver
    I want to execute this custom command on a file from the Gnome File Browser: hexdump -C $f > $f.dump That would create a hexdump of the file with the file's name + .dump in the directory that the file exists in. When I say $f above I mean something that would substitute the name of the file that was opened. So I've tried "Open with", "Use a custom command". I can't get it to work. I've tried a number of symbols in place of $f. Is it even possible? Before you suggest getting a GUI hexdump program, this is just one example. I have the need to do this sort of thing for many terminal-type programs. Am I the only person on Earth who wishes for a hybrid File-Browser-slash-Command-Terminal? That would be a file browser which contained a terminal pane who's current directory always matched that of the file browser. One could execute shell commands in the context of what they were viewing in the browser.

  • Cloning to a smaller hard drive with DDRescue

    - by krebshack
    I am currently working with a 700 GB Seagate hard drive that's beginning to fail. I'll call this "SDB" from now on. I'd like to clone it while I'm still able to. However, the only hard drive that I have available is a 500 GB WD hard drive. I'll call this "SDC" from now on. The partition scheme on SDB is as follows: 9.77 GB is allocated to a recovery partition and the remaining 688.87 GB is allocated to a Windows partition. Both are formatted using NTFS. There is no partition scheme on SDC. I know how to clone one hard drive to another using DDRescue but I've only done it using hard drives that are the same size. For your reference, I'll normally use the command "ddrescue -v -r 3 /dev/sdb /dev/sdc example.log". I'd like to know if it's possible to do this with DDRescue. I've read the manual from GNU (http://www.gnu.org/software/ddrescue/manual/ddrescue_manual.html) and I haven't seen anything indicating that it is possible. I'm just looking for some confirmation that this is a correct impression. If it's not possible, then it would be helpful if any of y'all would be able to make some work around suggestions. But please don't feel obligated to do that. I don't want to have my one thread bogged down with two many questions.

  • rsync per-site configuration file?

    - by Scott
    I know how to configure a per-site entry for ssh, but is there any kind of a client configuration for rsync that allows per-site configuration options and aliases or similar shortcuts like the .ssh/config? I'm curious because I have a minimal ssh server installed on my android phone and I also have a minimal rsync tool on it as well. I'm getting tired of having to root login onto the phone and sym-link both tools to standard places the android OS looks for executables as the ssh server is bare bones and has a typical *bear multi-link binary for the basic unix commands (that does not include rsync) I end up having to include --rsync-path=/path/to/rsync/android/files/rsync every time I want to do any rsyncing of the files on my phone, but this path is always the same. I've gotten around it in the meantime with a glob approach in a shell script wrapper, but this sometimes limits the customization I can do with the rsync call. I'm just wondering if there is anything similar to the .ssh/config file where I can create an alias for my phone (e.g. 'android') where specifying rsync android:/mnt/sdcard will automatically assume --rsync-path=/blah/blah/blah --no-g --no-p --no-t etc. Tre`

  • Package temperature above threshold, cpu clock throttled

    - by drN
    I am running 64 bit Ubuntu 11.10 on an i7 with 8gigs of ram. I thought of putting this on askubuntu.com but decided that maybe the question has a much broader appeal. I have the following error message popping up when I run math simulations. CPUn: Core temperature above threshold, cpu clock throttled (total events = xxxxxxx) CPUn: Package temperature above threshold, cpu clock throttled (total events = xxxxxxx) I realize that this is a hardware warning message (machine check exception, correct me if I am wrong). How do I turn these messages off? Since it doesn't seem to have a detrimental effect of my calculations or my computer (presumably), I don't like it cluttering up my virtual console screen with hundreds of these messages.

  • Batch converting video from avc1 to xvid

    - by Tommy Brunn
    I need a way to batch convert 720p video files from avc1 to xvid in Ubuntu 10.04. I'm not terribly concerned about file size, but I do wish to retain the picture quality as much as possible. I believe the audio is encoded as aac, which is fine for my purposes. What would be the best and easiest way to do this? I've tried using Handbrake. During my first attempt, I had it using ffmpeg to convert to MPEG-4, but that just gave me a super-low quality video at twice the file size. Trying h.264 now, so we'll see how that works out. But just in case it doesn't pan out so well, what other ways do you recommend? I was thinking I'd write a bash script to reencode the files one by one, but the problem is that I have very little knowledge about codecs and containers and whatnot - so I wouldn't know what parameters I would pass ffmpeg/mencoder.

  • Wireless performance on Ubuntu 9.10

    - by Brian
    Is there something I should do to my networking configuration in Ubuntu to better the performance of my wireless connection? I'm on a netbook dual-booting Windows 7 and Ubuntu 9.10. I pick up much stronger wifi signal when in Windows than Ubuntu. As soon as I boot Ubuntu, it will connect to the network with a stronger signal, and then loses signal very quickly. After it dies, I can't reconnect. I've tested this on a couple of different networks with the same outcome.

  • Is there any way I can add alternative key binding to a feature in compiz?

    - by vava
    I was wondering is there any way to add additional, alternative key binding to a particular feature in compiz? I am using Wall plugin and on my ThinkPad it is convenient to switch between horizontal workspaces with media buttons for browser navigation. But there just two of them, so I have to use completely different combinations to switch between workspaces vertically and that would very helpful if I can also use similar kind of combination to switch horizontally as well in addition to those media buttons. Is there a way maybe to send a message to the compiz to execute particular command? That would solve the issue.

  • lucid lynx runaway process

    - by Jerome
    I am runnning lucid lynx with a gnome desktop. After uninstalling the klipper program there is a new and unwelcome process that begins at startup and takes around 66% of my cpu time. According to "top", the process number is 10 and the name of the process is "events/1". I am unable to kill the process using "top" or "kill". I have no extra startup applications except for gnome-do and tomboy. Eliminating these has no effect. Can anyone help?

  • is there a way to prevent network manager from storing the password for a wireless network

    - by tolomea
    Our corporate wireless network uses continuously changing passwords with RSA tokens. So every time we need to connect to the wireless we need to enter a new password off the RSA token. For extra fun using the wrong password a couple of times in a row causes the users account to be locked. Network manager automatically stores and reuses the password, with the net result that it is constant getting my account locked. Is there some way to prevent it from storing my password for that network? Or perhaps someway to get the gnome keyring to not store it?

  • Gentoo+urxvt+terminus: How do I change font version?

    - by gaidal
    In my Debian installation I can type extended ASCII characters such as åäö by default using the terminus font, however in Gentoo I can't get it to work so far. Nothing happens when I hit those keys, like in this thread: Missing glyphs in Terminus font, how to setup a fallback font ? But in this case I know terminus supports those characters in at least some of its versions, since it's works in Debian. So what I want is to find out how to see and choose which of the many different terminus font files is being used. I set the font in the same way on both Debian and Gentoo, using URxvt*font: xft:terminus:size=xx in .Xdefaults. Both systems use en_US.UTF-8 as default locale.

  • Shell script to read value from a file and compare it to another one

    - by maneeshshetty
    I have a C program which puts one unique value inside a test file (it would be a two digit number). Now I want to run a shell script to read that number and then compare with my required number (e.g. 40). The comparison should deliver "equal to" or "greater". For example: The output of the C program is written into the file called c.txt with the value 36, and I want to compare it with the number 40. So I want that comparison to be "equal to" or "greater" and then echo the value "equal" or "greater".

  • Software RAID 1 broken, how do I fix this?

    - by Edward
    I'm running CentOS 6 x86_64. There is a software RAID 1 being used on the two internal 80GB drives. I got the following e-mail sent to me: A DegradedArray event had been detected on md device /dev/md1. Faithfully yours, etc. P.S. The /proc/mdstat file currently contains the following: Personalities : [raid1] md0 : active raid1 sda1[0] 511988 blocks super 1.0 [2/1] [U_] md1 : active raid1 sda2[0] 8190968 blocks super 1.1 [2/1] [U_] bitmap: 1/1 pages [4KB], 65536KB chunk md4 : active raid1 sdc1[0] sdb1[1] 1953512400 blocks super 1.2 [2/2] [UU] md3 : active raid1 sdd5[1] sda5[0] 61224892 blocks super 1.1 [2/2] [UU] bitmap: 1/1 pages [4KB], 65536KB chunk md2 : active raid1 sdd3[1] sda3[0] 8190968 blocks super 1.1 [2/2] [UU] unused devices: <none> The system appears to have booted fine and is working. The two drives' content did not change at all. I only removed and reinstalled them while I was booted on the CentOS Live DVD. How do I get the array working again?

  • crontab still sending emails even with > /dev/null

    - by user2344668
    I have a crontab (root) that runs a script and output is set to /dev/null but I always get the emails whenever it runs. I only want to receive error emails. # Rackspace driveclient update (12pm MST) 0 12 * * * /root/scripts/driveclient-update > /dev/null The only way I can get it to turn off is to use /dev/null 2&1 but then I won't get error emails. This is happening on three different CentOS servers, two are 6.3 and one is 6.4. NOTE: I have read over and over that /dev/null is supposed to send stdout there and prevent the email if there is nothing but stdout from the script, so at works for at least some people; I cannot figure out why it is not working on these servers. Here's an example of where /dev/null is supposed to work: http://www.alphadevx.com/a/384-Suppressing-Cron-Job-Email-Notifications

  • Accidental Extract Location - How to Clean Up?

    - by Gordon
    Sometimes I will do a command such as unzip tons_of_files.zip And I will forget to put a -d to point to a subdirectory. This causes the current folder to get filled with tons of files that are intermixed with the existing files. What is the best way to remove all these new files and/or move them to a new directory? I want to avoid having to manually examine the directory and determine if the file was part of the archive or was already present.
