Are you a Debian/Ubuntu Administrator or a regular user, then you may use the dpkg and APT commands often. These commands are used to install, remove, update or upgrade a package or the whole system. Mostly, we use the above two tools only for our day to day operations, But believe me, there are many useful commands are exist that most users aware of.
If you want to know which packages occupy the most disk space, or which package might have broken another, or to get a most recent version of a package, or just to get a particular version of a package, then you probably need Debian-goodies.
When developing a website, a web designer needs to be able to see his webpages the same way the end user would. Sometimes simply clicking on and viewing your HTML files in the web browser is enough, but if you want to test dynamic content, you will need to set up a local web server. Doing this is quite simple and can easily be accomplished on Windows, Mac, and Linux. There are many types of web servers available, but we will be using Apache as it is the most common server around, very easy to set up, and compatible with all major operating systems.
Just a few notes that may help anyone planning on upgrading from XBMC Frodo to Gotham on a Ubuntu Linux system. Many XBMC users will likely have already done this, but if you’ve been putting it off, here are some things to know:
First, before upgrading, enable the default skin (Confluence) in Frodo. That way, if your skin doesn’t work in Gotham, you won’t get thrown into a blank or unusable screen when you bring up Gotham for the first time. If that happens you may need to go into the directory where XBMC resides and completely delete the skin, losing any custom settings you may have had.
Also before upgrading, if you are running 5.1 audio or better then you need to see this page. Note that if you are trying to follow the instructions in section 3.1 (Passthrough Mode), the screenshots shown there are NOT of the default Ubuntu sound settings control. They are instead of the PulseAudio Volume Control, which you will likely need to install from the Ubuntu Software Center. Don’t let the fact that it uses the same icon as the Ubuntu Sound Settings fool you, it is NOT the same program.
After you upgrade to Gotham you can then follow the instructions on that page to get your audio working, and they will make sense to you. The main things are to set the checkboxes as shown in the PulseAudio Volume Control (preferably BEFORE firing up Gotham for the first time), and then enable Passthrough mode in Gotham (note you will need to set the settings level to Advanced to see that setting).
If XBMC crashes when you try to play a video and your system has NVIDIA VDPAU graphics, it may be because it tries to use VAAPI (check the last lines of the crash log). Go to System – Settings – Video – Acceleration and make sure anything having to do with VAAPI is not selected. This apparently didn’t matter in Frodo but it does on Gotham, but only on some systems.
Finally, you may need to refresh your XBMC repository – we found that it didn’t start bringing in updated add-ons until we did that. Try to avoid adding any new add-ons until you see the existing ones being updated because you may still be getting them from the Frodo repository, and they will be shown as incompatible or complain of missing dependencies when you attempt to install them. Go to System – Add-Ons – Get Add-Ons and right-click on XBMC.org Add-ons. Click “Check for Updates” then “Force Refresh” and it should start bringing in the updated add-ons. Don’t be surprised if several are marked as broken – not all add-on authors have supplied Gotham-compatible versions yet.
RSync or Remote Sync is the Linux command usually used for backup of files/directories and synchronizing them locally or remotely in an efficient way. One of the reasons of why RSync is preferred over all other alternatives is the speed of operation, RSync copies the chunk of data to other location at a significantly faster rate. This is because, whenever Rsync is executed for the very first occasion, it transfers all the data from source to the destination. On the next turn, it would just copy the files/directories whose contents are changed.
The concept of app stores, though popularized by Apple, followed by Android, has been around for a long time. In fact, Linuxians know that it was in the penguinian world of software that the concept of app store basically originated. A software housing a collection of apps stored in a convenient location was something Linux users have loved and still love.
That said, if you are an Ubuntu user, you probably must have gotten tired of using Ubuntu Software Center already. It’s clean, sleek, and does what it says on the tin; however, as a FOSS enthusiast you might be looking for something different. If that’s the case, then we have for you a list of alternative app stores for Linux that will help you get the software you need instantly.
For any person, who does not have a sound knowledge of Linux Operating System and Linux File System, dealing with the files and their location, their use may be horrible, and a newbie may really mess up.
This article is aimed to provide the information about Linux File System, some of the important files, their usability and location.
