In part 3 of the series, I am going to go through the important things that you need to do after you have got Jaunty up and running. 1) Enable the repositories Every time I do a fresh install of Ubuntu, the first thing that I do is to enable the universe, multiverse, backport and Canonical’s ‘partner’ repositories.

New cool list of Linux must-have programs. Update: A new, up-to-date collection is available. Please take a look! It's been approximately two years since I've written the first article, A (cool) list of Linux tools. The article proved quite popular with my audience, as it allowed Linux users, new converts in particular, a quick taste of some of the more useful programs available for Linux platforms, across a range of categories.
Since, a lot has changed. Two years is a long time. I have decided to write a new article, from scratch, cataloging an up-to-date collection of must-have programs. Changes from the last time Like the last time, the programs will be sorted by categories. Games I will not be listing games here. Users' recommendations Likewise, there's a users' recommendation sub-section, so you can send me your suggestions and ideas.

I won't mention that this legacy operating system did not support user quotas; that's another story. But the server kept getting full and stopping people from working. One of the software engineers in our company spent the better part of a day writing a C++ program that would look through the directories of all the users and add up the space they were using and make a listing of the results. Du -s * | sort -nr > $HOME/space_report.txt Graphical user interfaces (GUIs) are helpful for many tasks, but they are not good for all tasks. I once heard an author remark that when you are a child you use a computer by looking at the pictures. Scripting the Linux desktop, Part 1: Basics. Developing applications for the Linux desktop typically requires some type of graphical user interface (GUI) framework to build on.
Options include GTK+ for the GNOME desktop and Qt for the K Desktop Environment (KDE). Both platforms offer everything a developer needs to build a GUI application, including libraries and layout tools to create the windows users see. This article shows you how to build desktop productivity applications based on the screenlets widget toolkit (see Resources for a link). A number of existing applications would fit in the desktop productivity category, including GNOME Do and Tomboy. These applications typically allow users to interact with them directly from the desktop through either a special key combination or by dragging and dropping from another application such as Mozilla Firefox. Getting started with screenlets You need to install a few things to get started developing screenlets. Next, download the test screenlet's source from the screenlets.org site.

Remove Ubuntu Kernels You Don’t Need. Every time Ubuntu installs a new Linux kernel, the old one is left behind.
This means that if you are regularly updating an Ubuntu system the Grub boot menu becomes longer and longer with kernels you don’t need anymore. The old kernels are deliberately left installed and on the menu so you can boot a previous kernel if you have trouble with a new one. But if the new one works, you can safely uninstall the old kernel, which will also result in the Grub menu being cleaned up.
First you need to find out what your current kernel is. Open a terminal and run the following command: uname -r It will print the version of the Linux kernel you are running, this is the one you want to keep. 2.6.20-16-generic Open the Synaptic package manager from the System->Administration menu.

Features The app lets you back up and restore the following: Using Aptik. 20 Linux System Monitoring Tools Every SysAdmin Should Know. Need to monitor Linux server performance?

UnixTutorials - Tutorials and howtos for Unix based operating systems (Linux, Ubuntu, BSD and more) Linux Directory Structure (File System Structure) Explained with Examples. By Ramesh Natarajan on September 8, 2010 Have you wondered why certain programs are located under /bin, or /sbin, or /usr/bin, or /usr/sbin? For example, less command is located under /usr/bin directory.
Why not /bin, or /sbin, or /usr/sbin? What is the different between all these directories? In this article, let us review the Linux filesystem structures and understand the meaning of individual high-level directories. 1. / – Root Every single file and directory starts from the root directory.Only root user has write privilege under this directory.Please note that /root is root user’s home directory, which is not same as /. 2. Contains binary executables.Common linux commands you need to use in single-user modes are located under this directory.Commands used by all the users of the system are located here.For example: ps, ls, ping, grep, cp. 3. 4. 5. Contains device files.These include terminal devices, usb, or any device attached to the system.For example: /dev/tty1, /dev/usbmon0 6. 7. 8. 9.
