BASH can be a difficult shell to use and many commands may be too long to type. Some users may find some commands to hard to remember, and then other users want to customize BASH and make it more interesting. This article will help to solve some of these issues and show readers how to make BASH better.

Linux, like other operating systems, has a desktop with a wallpaper. This wallpaper can be customized in many ways. Users can use one wallpaper, or they can make the wallpaper change to one of many wallpapers after a set time. Applications that change the wallpaper after a set time without the user's help is called a wallpaper changer. Three of the most popular wallpaper changers are Wallch, Cortina, and Wally. However, there are others, but they may not be stable.

In this article I would try to explain iscsi storage configuration on linux distro. We will first need iscsi initiator installed , that will use iscsi commands to communicate with the iscsi storage. What I would care more on this article , is to understand usage is iscsi commands to access / manage storage. First requirement is to install iscsi package and you can use open iscsi from open iscsi or you try installing using yum.

I recently purchased some KVMs from a good provider of mine and decided to migrate from VPS to KVM. In doing this, I set up some LXC containers, installed Apache on them and copied over my data. That, was the easy part. Now I had to find a way to let the world view my websites. From a previous time not too long ago (which I'll write an article up for here), I proxied web requests via Nginx to the containers' web servers. I could do this easily with HTTP, but as I also needed HTTPS this posed an issue. What better way to learn though than diving right into it in a production environment, right?! Lets go!

On Linux, Cairo Clock is a very popular clock that many users love. Numerous developers have made a variety of looks for this clock called themes or skins. This article will provide information on making, downloading, installing, activating, deleting, and sharing Cairo Clock themes.

Gedit is a popular text editor that many users use to write notes, create BASH and Python scripts, view configuration files, etc. Sometimes, users may want to change the way Gedit displays text. This is very useful to programmers. Gedit gives specific colors to the variables and another color for the commands. Many parts of the programming syntax has a special color. This programmer can immediately identify parts of the code by seeing the color. However, what if the programmer is color-blind or does not like the way some of the colors look? Thankfully, a simple XML file can instruct Gedit how to display programming syntaxes and plain text. This single XML file, that averages around 10kB, is called a Style Scheme or a Syntax File.

Many Linux applications allow users to customize a program’s appearance. These alternate looks are skins (themes for individual applications); themes are another term (for example, themes used in Firefox). Below are three common media players that users may want to customize.

Shell script writers may write a script that runs slowly, but the programmer cannot figure out what code is causing the issue. Even if they find the problem, they may have difficulties finding a better way to write the code. This article will show inefficient code and how to write efficient script. This article will also show methods of writing code to make the code execute quickly.

Bash is a commonly used scripting language for shell scripts. A script is a small list of instructions for the computer to follow. A scripting language is a programming language used in a script. Shell scripts are scripts written in a shell language, and a shell language is a programming language used within a terminal. In BASH scripts (shell scripts written in BASH) users can use more than just BASH to write the script. There are commands that allow users to embed other scripting languages into a BASH script. This article will explain how to embed several languages into one script.

With Linux, it is easy to customize many settings and features including appearance. Unity (one of many desktop interfaces) is no exception. Unity is the desktop interface that is maintained and developed by Canonical. Canonical uses Unity as the default interface for their popular operating system - Ubuntu. Users can easily change the theme, cursor, icons, and fonts used in Unity.

IPv6 has begun to pick up a bit of steam. What was once just fancy talk of the new Internet has now started to take shape and really become a focal point of the Internet. There are VPS (virtual private server) companies out there now that offer IPv6 only. One of the greatest (and possibly worst) aspects about this is that those with IPv4 only are not able to access such servers.

Any gamer or fan of distributed computing would tell you that a powerful graphics card is key to a high performing computer. That same gamer would also tell you that a sign of a good graphics card is the ability to overclock it. After all, overclocking means greater performance and greater value.

If you use Linux for ethical reasons then that may be a reason to be consious of our limited and dwindling resources, if you are interested in saving the environment you can refrain from burning a CD or DVD to install your favorite linux distribution.

In this day and age, you really want to make sure your data is safe on your server. One popular tool to help do this is the CSF/LFD package (ConfigServer Firewall and Login Failure Daemon).

I felt this was needed for all the many people here who may wish to develop their site without the need for a control panel such as cPanel (just dos prompt / command prompt). Typically those of you seeking to use a VPS, Semi-Dedicated, or Dedicated Server for the first time or who are generally new to Linux.

Insync announced late last night that their desktop application is now available for Linux users. This means you can have dropbox-like functionality on your Google Drive! It is in beta, but most users that have installed it already are raving about it so far.

This article will show you some of the top Android apps available out there so that you can see what's going on all the time right from your phone. These apps are optimized for your phone's screen so it makes it a lot easier to get around and get all of the info you need.

I originally planned on writing an article over Common Table Expressions (CTEs) but since MySQL does not currently support CTEs, and there has been much debate as to why they should implement it, I decided not to write an article about it. MySQLs answer to CTEs is Temporary Tables. A temporary table is a base table that is not stored in the databse, but instead exists only while the database session in which it was created is active. In this article we will look further at what a Temporary Table is, how to use them and when it is appropriate to use them.

Nagios, one of the most popular network monitoring software out there. While the software itself is pretty intensive very robust, the web UI leaves a bit to be desired. For starters, it does not graph trends regarding to hosts and services. This isn't a big missing feature, but it would still be nice to have. However, there is one feature that I really wish was implemented, especially with the general concept being easy to handle, and that is ACL (access control list). With Nagios, you can have multiple accounts to login to the web UI, but everyone could see every server. As I wanted my clients to view just theirs, this was not acceptable.

In this tutorial we are going to review indexes. I never cease to be amazed at how many people do not know what indexes are or how to use them. An index is simply a data structure that provides a fast access path to rows in a table based on the values in one or more columns (the index key). This allows for fast search techniques to be used to find the values ,rather than having to scan the entire table row by row, which results in much faster data retrieval. This can be a big performance booster in your environment, lowering the amount of time it takes to run a SELECT query and get data back.
