Breaking the SHELL

Post date: May 29, 2005, 01:05 Category: Programming Views: 3264 Comments
Tutorial quote: Shell scripts are a part and parcel of almost all software applications running on UNIX, and the use simply spans from a trivial script, managing automatic database backup to bunch of scripts collaboratively doing complex operation on regular expressions.

Though it's a mere design decision to partition modules between scripts and programming language, but I personally feel that they sometimes come very handy saving lot of time and lines of code, when compared to implementing the same functionality in the programming language in context.And in fact with some exceptions, complexity of a shell script can scale to that of codes in C language. Add to this the power of all those numerous UNIX commands, and just think through, what can be achieved by shell scripts.
Here I will discuss few topics mainly relevant to intermediate shell programmers

Writing Shell Scripts

Post date: April 13, 2005, 02:04 Category: Programming Views: 3806 Comments
Tutorial quote: With the thousands of commands available for the command line user, how can you remember them all? The answer is, you don't. The real power of the computer is its ability to do the work for you. To get it to do that, we use the power of the shell to automate things. We write scripts.

An Easy Way To Install Gnome Shell

Post date: September 21, 2009, 16:09 Category: Benchmarks Views: 3757 Comments
Tutorial quote: Gnome Shell consists of two big parts: the panel and overlay. The panel part is pretty much obvious - system tray, user name, and clock stuff and the activities button which activates the overlay -, and about the "overlay", well, take a look at this screenshot:


Basically, it allows the user to concentrate on switching to a new activity by opening new applications, documents, or both. It displays all the current user workspaces and open windows and facilitates organizing them.

So far, the Gnome Shell installation was quite time-consuming, so most people didn't try it until now. With time, however, this has changed, and you can install it by running a script. Here is how:

Managing Xen With Xen-Tools, Xen-Shell, And Argo

Post date: November 5, 2006, 21:11 Category: System Views: 4312 Comments
Tutorial quote: This guide describes how to install and use xen-tools, xen-shell, and Argo on a Debian system. All three packages provide useful tools for the administration of virtual Xen machines. Xen-tools is a collection of Perl scripts that allow you to easily create, update, and delete Xen guest domains. The xen-shell provides a command-line interface to owners of Xen domains so that they can manage their Xen domains without the help of the server administrator. And with Argo, you can control Xen domains through a web interface or through a menu on the command line.

Automating the Login Script

Post date: April 17, 2005, 10:04 Category: Miscellaneous Views: 2522 Comments
Tutorial quote: In a perfect world, you could spend a few weeks creating a system and the result would be a system that never required manual maintenance or modifications. Whether this ideal will ever be achieved is debatable, but it definitely won't happen in the near future. In the meantime, we still have to do things manually, even if only once in a while. When I must do things manually, I'm not usually happy about it. In fact, it usually means that there has been an emergency, so other people aren't happy about it either. In times like this, it is nice to have a consistent and efficient user interface on every machine. The information and examples presented in this article assume that you are using the bash shell. However, you can modify all of the scripts so that they work in other shells. In some cases, they might even work unmodified (like in the standard Bourne Shell [sh]). Other shells will also work, but they might have different methods for changing the prompt and creating command aliases. The principles in this article should be relatively easy to adapt to the shell of your choice.

Tutorial quote: Have you ever wished you had another computer handy? Maybe you want to try a new operating system out. Maybe you want to test something experimental without potentially breaking your own system. Maybe you need to run some software that only runs in a different operating system. Mandriva Linux 2007 Spring comes with a range of virtualization options that can help.

Have a Bash With This Linux Shell

Post date: April 15, 2005, 05:04 Category: Programming Views: 3150 Comments
Tutorial quote: Any Linux administrator who wishes to remain sane relies heavily on scripting to automate routine tasks, customize jobs, and build the plumbing that connects the different utilities that make a Linux system run smoothly. The Linux world is chock-full of scripting languages: Perl, Python, PHP, Scheme, Tcl, Tk, Ruby, Forth, Smalltalk, Eiffel, and doubtless many more. To get the column started, we'll look at shell scripting with Bash, and scripting with Python and Perl.
