Command line tricks for smart geeks Everyone knows the answer to the question of life, the universe and everything is "42", but for the first time we can reveal the question. It is this: how many command-line tricks must a man memorise? You see, graphical user interfaces are all well and good, but when you want to get real work done it's time to switch to the terminal. And so, we squeezed our brain cells, dug through dusty piles of old issues of Linux Format, and sat reflecting quietly over many a pint of ale, all with the goal of bringing you this: 42 awesome new command line tricks we think you ought to commit to memory. So, strap yourself in and get ready for command-line heaven: it's time to kick ass and chew bubble gum, and we're all out of gum...

4 Strange And Disturbing Linux Distros You Probably Won’t Be Installing Linux is the operating system of choice for those who decide to go their own way. The open source model means the building blocks are there for you if you decide that you need your very own operating system. This has resulted in more Linux distros than you could ever imagine. I’ll be saving the very worst for last, so prepare yourselves… Ubuntu Satanic Edition The distro of choice for satanists the world over, Ubuntu Satanic Edition is proof that there’s an Ubuntu distro for everyone. If you’d like to try out Satan’s own OS then you’ll have to download a live CD, which the team have predictably dubbed the “undead CD”, though I can’t really see why you’d be doing that. Ubuntu Satanic Edition has received numerous complaints and messages of discouragement. Hannah Montana Linux While most people won’t find Hannah Montana Linux anywhere near as “offensive” as the previous distro, it’s still probably not going to be your OS of choice unless you watch way too much Disney channel.

40 Linux Shell Commands for Beginners | A Platform to Express Your Ideas and Thoughts | fortystones Linux has more than 650 commands and every command has its own set of options all performing different operations. Going through each and every one of these commands will be a very tedious task. However limiting yourself to only a few of them is never an option. The trick here to learning all these commands, is to categorise them according to their function. By doing this, you will know atleast the basic commands and have some measure of control over the Linux command line. When you go through these commands, you will be able to perform different function as per your need in the Linux command line.

How to check graphics card on Linux How to check graphics card on Linux The increasing popularity of Linux and Linux-native gaming platforms such as Steam is bringing mainstream gaming to Linux. If you are a hardcore gamer, you will probably pay great attention to the performance of the graphics card on your system. Many of you may be willing to shell out a couple of hundred dollars for high-end video cards to enjoy maximum gaming experience. In this tutorial, I will describe how to find information about a video card and video driver used in Linux system. Method One The first method to determine what graphics card you have is by using lspci which a command-line tool for showing all PCI devices. Before using lspci, it's a good idea to update PCI ID list with the latest version as follows. $ sudo update-pciids Then use the following command to show the vendor/model names of your video card. $ lspci | grep -E "VGA|3D" 00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09) $ sudo lspci -v -s 00:02.0 Method Two $ hardinfo
Configurer correctement son clavier Mac sous Debian 11/12/2013 DayByDay En me levant en plein milieu de la nuit, il m’es apparu évident que je devais vous parler du mappage clavier d’une VM Debian sous OS X. En avant. Le problème Lorsque vous montez une machine virtuelle Debian (ou Linux de manière générale), il y a peu de chance que votre clavier Apple soit correctement configuré. Généralement, les touches les plus fréquentes sont ok, mais dés que vous voulez taper un “@“, ça écri un “æ”. Sur le même principe, vous ne pourrez pas saisir de “|”, ce qui peut-être très contraignant si vous devez jouer à un autre niveau. La solution Il vous suffira d’éditer le fichier /etc/default/keyboard. Tapez nano /etc/default/keyboardafin d’ouvrir le fichier de configuration dans un éditeur de texte basique. Remplacez les valeurs des champs, pour qu’elles correspondent à ce qui est ci-dessous : XKBMODEL="pc105" XKBLAYOUT="fr" XKBVARIANT="mac" XKBOPTIONS="lv3:switch,compose:lwin” Enregistrez et quittez, puis redémarrez avec un petit reboot.

Articolo originale: Linux è conosciuto per il suo potente firewall chiamato iptables. Tuttavia questo firewall deve essere gestito da linea di comando, usando dei lunghi e difficoltosi comandi. Pertanto è virtualmente inaccessibile per la maggior parte degli utenti. In Ubuntu la situazione è anche peggiore in quanto il firewall è disbilitato di default e non c'è una via semplice per avviarlo. Questo tutorial vi mostrerà come potrete gestire facilmente il vostro firewall Linux usando gufw, avviando/fermando il servizio, creare regole, monitorare i logs, ecc. - tutto senz accedere alla linea di comando. Installare gufw Per quanto riguarda Ubuntu 8.10 Intrepid Ibex, gufw è incluso nella repository, quindi l'installazione è affare di circa 14 secondi. Avviare gufw gufw può essere rintracciato in Sistema > Amministrazione > Firewall configuration. Il menu principale apparirà grigio fino a che non abiliterete il firewall.

From Techotopia In Ubuntu 11.04 Firewall Basics we looked at ports and services on an Ubuntu 11.04 system. We also briefly looked at iptables firewall rules on Ubuntu including the creation of a few very simple rules from the command line. In this chapter we will look at a more user friendly approach to iptables configuration using two tools named gufw and ufw. [edit] An Overview of gufw and ufw Included with Ubuntu 11.04 is a package called ufw which is an acronym for Uncomplicated Firewall. [edit] Installing gufw on Ubuntu Whilst ufw is installed on Ubuntu 11.04 by default, the gufw package is not. sudo apt-get install gufw Enter your password when prompted to do so and wait while gufw is downloaded and installed. [edit] Running, Unlocking and Enabling gufw Once installed, launch gufw by pressing Alt-F2 and entering gufw into the Run a command text box. To unlock gufw simply click on the Unlock button and enter your password when prompted to do so.

PS3 Linux - GPU computing

Installing Ubuntu on PS3 - PSHomebrew Note: Linux support on PS3 (that does not use OtherOS) is experimental. Whilst there is very little chance of damaging your console the current implementation of Linux may be unstable or include bugs. After following this tutorial you will: Have Ubuntu installed on your PS3. Have performed a few optimizations to to improve performance. Prerequisites A PS3 (Fat or Slim) with kmeaw's 3.55 CFW installed (other firmware versions may work but have not been tested). 10GB of free space on either internal or external drive. Initial Setup Either extract the Ubuntu image files to the root of an external drive or FTP them to the root of the PS3 internal drive (dev_hdd0) (Yes, the files should extract to around 10GB. Using PS3 VRAM as SWAP This will allow you to use the PS3 vram as a swap partition. Open terminal (it is the middle icon on the bar at top of the screen). This will only work until you reboot so we must now alter the ubuntu boot files to do this automatically when it starts. ps3vram
Petitboot is a graphical bootloader for the PlayStation 3. It's based on the existing kboot project, plus the twin windowing system for the GUI. At present, petitboot is very much a work-in-progress, but works on our test PS3. Petitboot is licensed under the GPL v2. screenshots download Petitboot, version 0.2: otheros.bld (PS3 flash image, 3.4M) The installing section below has instructions on installing petitboot. I have another image, same as the above, but with a telnet server, a ssh server and a http server enabled. otheros-petitboot+network.bld (PS3 flash image, 3.5M) You will need to rename this to otheros.bld after you download it. installing Put your otheros.bld file on to a USB disk, in a file called /PS3/otheros/otheros.bld. using petitboot When petitboot starts, it will try to find existing Linux installations, by looking for /etc/kboot.conf, /etc/yaboot.conf or /boot/petitboot.conf files on any storage device connected to the system. The keys available are: console sources building authors petitboot
Debian LiveCD - PS3 Developer wiki Sometimes we need to boot Linux without HDD e.g. if you want to experiment with HDD encryption, enable/disable it without causing damage to your data. For such cases we need a LiveCD which doesn't mount HDD at boot. cd /root/livecd mksquashfs * ../root.sfs cd /root unsquashfs root.sfs cd squashfs-root # Make your changes mksquashfs * ../root-changed.sfs We need a Linux 3 kernel with overlayfs support so we could create a tmpfs over our read-only base filesystem. See my GIT repos: See my GIT repo: BusyBox[edit] We need a couple of user-space applications to mount filesystems, load kernel modules and so on. tar xvjf busybox-1.20.1.tar.bz2 cd busybox-1.20.1 make menuconfig make Creating Image[edit] USB[edit] And create kboot.conf in the root directory of your USB drive with this content: debianlive=/debianlive/vmlinux-3.6.4 initrd=/debianlive/initramfs.cpio.gz CDROM[edit] (files seem missing)
