Efficiently Using the Launcher. Learning some basic methods to navigate and customize the launcher can make it an efficient tool that is used to complete daily tasks. With several icons located in the launcher, reordering the applications may reduce your time searching for your desired program to execute. The images above show the steps involved in changing the order of the icons in the launcher.
First, click and drag the icon you would like to move off of the launcher. In the example above, Banshee is being moved from below the System Monitor to below the Calculator application. If there are many icons in the launcher, it may not be possible to display them all at the same time due to space constraints. The image to the far left shows that there are too many icons in the launcher to display full size.
In the next image, the launcher is in the process of scrolling down. In order to reduce the number of icons present in the launcher, it is straightforward to add icons to the desktop that will launch applications. Re/Instalar Ubuntu desde cero sin perder los programas ya instalados en una versión anterior. « HATTERAS'S BLOG LINUX (sobre Ubuntu y derivadas ) Ubuntu 12.04 – How to Completely Uninstall/Remove a Package/Software/Program | Complete, Concrete, Concise. This tutorial shows how to completely remove or uninstall a package in Ubuntu 12.04. These instructions should work for other versions of Ubuntu, it’s derivatives (Edubuntu, Kubuntu, Lubuntu, Xubuntu, Ubuntu Studio) and other Debian based Linux distributions – but no guarantee is made.
This tutorial is definitely on the advanced rather than basic side of things, but if you are careful, it shouldn’t be a problem. There is a small but real risk of data loss or making other programs or Ubuntu unusable. It is advisable to ensure you have a backup before proceeding. I am somewhat over emphasizing the risk, but anything can happen – there might be a power failure in the middle of uninstalling and this might leave your system in a funky state, or you might select a critical system file for deletion and this leaves your system unusable.
I don’t expect anything bad to happen, but I make no guarantees. You can jump directly to the How To part here. My best guess is because it is a low priority: HTG Explains: Which Linux File System Should You Choose? File systems are one of the layers beneath your operating system that you don’t think about—unless you’re faced with the plethora of options in Linux. Here’s how to make an educated decision on which file system to use. The landscape of the Linux file system support is drastically different from Windows and OS X. In Windows and OS X you can find software that will add support for non-standard file systems, but both operating systems can only be installed on their native file system and third party support is added after the fact. Linux on the other hand has a vast array of supported file systems built into the kernel.
What is Journaling? Before we go to far down the rabbit hole talking about options, we need to first take a quick look at journaling. Journaling is only used when writing to a disk and it acts as a sort of punch clock for all writes. With a journal the file is first written to the journal, punch-in, and then the journal writes the file to disk when ready. File System Options. [Ubuntu Tip] Change Ownership of Files / Folders. This quick tip shows you how to change the ownership of files and folders in Ubuntu.
This will work in all versions of Ubuntu, including Ubuntu 11.10 (Oneiric Ocelot). When you use the sudo command to install packages or create folders, the root account automatically assumes ownership. And if a regular user wants to edit or modify the file of which the root is the owner, he or she will be denied. In this case, you’ll have to give ownership of the file to the user who will be modifying it, and this is why this tutorial is here. Without wasting anymore of your time, let’s continue below to learn how. Objectives: Change ownership of files and folders in Ubuntu Enjoy! To get started, press Ctrl – Alt – T on your keyboard to open Terminal.
The first thing you might want to do is list the content of the current directory. Ls The ls command lists the content of the current directory. To change the ownership of a single file, run the command below. sudo chown <username>:<groupname> filename That’s it! How to Use 7zip in Ubuntu Linux Without Knowing Commands. As of version 4.43 beta, 7-Zip doesn’t yet provide a graphical user interface (GUI) for Linux.
Ubuntu’s Archive Manager (file-roller) provides some help, but it doesn’t support multi-volume archives. If you haven’t yet installed 7-zip, go here. Below, I’ve created a simple form that you can fill out to generate 7z commands. You can copy these commands directly into your terminal at the command prompt. Unfortunately, I only had time to support the features I commonly use, which is certainly a limited set of what you can do with 7-Zip. However, I hope you’ll find this to be a useful bookmark. Where is the folder or file you want to archive? (example: /home/user/Desktop/FolderName) In which folder, do you want the output file(s) to be placed? (example: /home/user/Desktop) What would you like to name the output file(s)?
(example: fileName) What level of compression do you want? Would you like the output to be divided into multiple volumes? Click the button above to generate your command below. Baobab: A Tree To Discover Your Disks' Usage [Linux] Keeping an eye on your disk is always very important, especially today when dealing with huge quantity of data. Take a look at your personal files and programs, and you will be surprised by how much disk space you consume. Baobab is a Graphical User Interface software to analyze a disk usage. Hopefully, Baobab can help you manage that, straight out of the box, and with very little installation required. At the risk of repeating myself, the installation is very simple. For other distribution, check your repositories (here for Archlinux users). Now that Baobab is on your computer, you can launch it and use it without any further configurations. You can choose between two ways of representing the disk distribution: the ring chart or the tree map.
The GUI is composed of three panes: at the top you can choose what to analyze, on the left is the directory tree, and on the right is the graphical representation. About the analyze functions, their usage is fairly simple. [How to] Remove Multiple Players from Ubuntu Sound Menu. With several media players installed the Ubuntu Sound Menu can quickly become over populated – so how do you go about removing entries? The quickest way to remove music app entries from the Sound Menu is to uninstall the media players themselves. After all, you are likely to only use one at a time. But if you don’t want to remove them (and there are legitimate reasons for keeping more than one installed, see below) but also don’t want them appearing in the Ubuntu Sound Menu, the option to remove them does exist. My use case, for example: I use Beatbox to play my local tunes, but keep Spotify for Linux and Nuvola handy for any cloud-based streaming. But I keep Rhythmbox installed for one purpose: to buy music through the Ubuntu One Music Store, so I find the Sound Menu entry for it surplus to my requirements.
How to Remove Media Players from the Sound Menu But when in doubt, just keep out! On to the tutorial. Click to install Dconf-Tools Next, open Dconf-Editor in the Dash. ['rhythmbox'] Or. Everything You Need to Know About Mount [Linux] Until Windows 8, a PC had no native support for ISO files. A little piece of software could help you cope with that very easily, but you still had to install it by yourself.
On Linux, you can mount any ISO or file systems immediately with a simple command. However, it can be a little tricky to manipulate devices, especially if you were used to Windows before. You have to think using Linux’ philosophy: everything is a file. Therefore, a device can be considered as a folder, which is a file in itself. First of all, you will need the super-user rights in order to mount anything on your computer. After the parameter “t”, you should provide the type of the file system that you are trying to mount.
Auto/noauto for automatic mounting or notexec/noexec to specify if the binaries on the file system can be executed or notuser/nouser to determine if any user or just the root can mount the devicero/rw which stands for “read-only” and “read and write” With the option “v” standing for verbose mode.

There are a great number of Linux users who dual boot their computer with Windows. And in situation like this, one has to make different partitions to separate Windows and Linux partition. Windows usually (not always) uses NTFS file format while Linux is usually (again, not always) installed in Ext3 or Ext4 file format.
While using Linux, one has to manually mount the drives. It doesn’t take time in mounting but in some situation you might prefer to have it automatically mounted at each start-up for e.g., if your Music files are on the NTFS partition and you want to use the same directory in Linux it is advisable to auto mount that drive. In this tutorial I will show you the easiest way to mount Windows NTFS partition at each start-up. One way to automount NTFS drive is by editing fstab, but that might not be simple for beginner Linux users.
An alternative way is to use a GUI tool named ntfs-config. Open the terminal ( Ctrl+Alt+T ) and use the following command to install the tool: How to mount a windows partition on Linux automatically on each start up. Knowing Your Linux System Via the Command Line. Every Linux user will tell you the same thing: know your computer. Mine always works not because there are no bugs, but because I know enough to identify their sources every time and correct them. And one of the best ways to monitor your system is through the command line. There are some great GUI for this, but the command line has the advantage of working on every computer, and it can easily be put into a script. I propose to you five great commands for: Knowing your kernelFinding hidden processesListing running modulesChecking disk usageLocating binaries and configuration files The kernel is the core of your Linux system.
To know exactly what kernel you are using, its version, and your computer architecture, use the command: With this example, we can clearly see that I am using the official kernel, version 3.0.0. To know what processes are currently running on your machine, most people would recommend the command “top“.

In earlier Ubuntu versions, these files were simply used so as to launch a specific application, but in Unity they are also used so as to create right-click menus for each application, which you can access from the Unity Launcher.
This article describes how to create a working .desktop file for general use, but also how to add it to the Unity Launcher and/or how to edit a Unity Launcher itself, by editing its fields or by adding a right-click menu to it. There are currently 2 ways of creating a desktop file. The 1st one is using a text editor, like Gedit, and the 2nd one is installing a program (gnome-panel) or using 'alacarte' that both do the job for you. The former lets you "control" your launcher more than the latter, but the latter way is easier. Please note that this section will cover only the basics, not how to add shortcuts to your launcher.
