Data Movement in Linux – Often No More than Renaming

Strictly speaking the file still has not moved.  The data bits are still on the same part of the disk where they were in the first place originally.  The file specification ( the-directory-path plus the filename) that you use to talk about the file is different so that it appears to have moved , whereas it has not in actuality.

In early versions of Unix , the users were not allowed to use mv to move a file from one disk partition to another , you could only copy it ny using the  cp(1) command.  Linux allows you to use the mv command to move a file anyplace.  Normally , mv leaves the data in place and just changes the file name or the directory where the name is placed.  But when the file is moved across the disk partitions ( for example form /usr to /home in a lot of Linux systems) , the data is copied to the new disk partition, the new name is put in place.  In that partition’s directory structure, and the name and file data are removed from the old disk partition.

Moving and Copying Files and Directories

The command for moving and opying directories and files are mv for moving and cp for copy.  If you want to rename a file,  you can use the move command .  No you are not really moving the file, but in both Linux and Unix , the developers realized that renaming something was a lot like moving it .

Hence the format of the move command is    my < source>  <destination>

With the example files, you could move the file named stupidkirk to a file named  evenmorestupid  by executing the following command

mv  stupidkirk evenmorestupid

This leaves the file in the same directory, but changes its name to  evenmorestupid .

Hence the file is not moved – it is just simply renamed .

Next you can try moving the evenmorestupid  file to the top of the stupidpeople directory.  To do this you first have to move the file up and then move it to the stupidpeople  directory.

This can be done with one simple command :

mv evenmorestupid ../ stupidpeople

Lastly note that the destination file uses the ..( or parent) directory designation.  This tells Linux to go up one directory level and look for a directory called stupidpeople . and then put the file into that directory with the name stupidpeople,  as you did not specify any other name.

Linux Foundations for a Complete Customer Orientated Solution

The basis of the planning was to lay the foundation for a Linux that could deliver complete customer orientated solutions – across a range of vendors and suppliers. In essence many of these same vendors were competitors either for product software applications or services. That was both a challenge and a bonus. It was all in their best interests – both from a software flexibility , development and customer satisfaction viewpoint to provide the most stable , flexible and modifiable Linux base platform.

This is the situation that a United Linux framework came into play. The aim of the United Linux project was to address all of these crucial areas of software and customer satisfaction areas of concerns as well as to provide base flexibility and stability of the Linux operating system , systems and applications. Linux had to be all thing to all people and customers as well as provide a most stable , and secure application level standards.

The aim was to provide a mechanism of a single point contact by which IHV’s and ISV’s could get dependent drivers , utilities into a commercial LSB compliant OS implementation.

United Linux Specs as well as Coordination Blueprints

On top of this the United Linux participants were to include supplementary media which would of provided easy opportunities which would allow easy configuration and even branding of the distributions look feel install applications and value added services.  The obvious point in this was – apart from the branding is that each of partners could produce task or region or regions specific offerings that still adhered to the United Linux overall specifications and specs .

Common U.I. United Linux Development History

The first part of the plan was for the four partners to pool their development resources to create the U.I. ( United Linux) core. This was a single CD containing the basics of the operating system drivers and at that time a state of the art linux installation program. The whole distro was meant to be an enterprise grade solution , which as a start was based around SUSE’s enterprise Linux Server product of the time. The core application itself was based on work already completed by the Linux Standard Base of that time and was to be compliant of the then current standards for things like web services. authentication and file system hierarchy , it was intended in the first instance on x86-32 , IA64 , and X86-64 platforms and was aimed predominantly at business users and useage

Colloborative Linux Distro

These individual distros and their partners hoped that other distros of Linux would be marked under their respective brands, but would be powered by a consistent United Linux which mean that the user could be confident that the user would be published with a United Linux and thus a measure of consistency and user functionally would easily exist across a customer and user base – for the first time in the Linux unix user base and communities.

Thus the UI ( United Linux) brand would thus of reduced the amount of mainstream Linux distros to the well managed group of five (5) – that at the time being Red Hat, Mandrake , United ,Debian and Slackware. The bets were on that time that in the enterprise sector tht Re Hat and United Linux would come to dominate. Well at the time those were the predictions of the Linux market share dominant distros.

Linux History – June 2002 – 4 Major Vendors Join Forces

In June 2002 four of the largest Linux distribution vendors joined forces to break down what they had identified as the main barriers to the widespread adoption of Linux in an enterprise- Caldera , SuSE, Conectiva and TurboLinux announced that they would collaborate on a common Linux fore to create the next generation of a Linux Distribution ( distro) to make deploying and supporting software easier and resolve the common problem of binary incompatibility between Linux distributions.

History of the Open Source Linux Computer Operating System

Some called it a bold move securing the future of the operating systems of computers at the time , from the evil empires. Some saw it as a way to gain their fellowships , other saw it as the cost saving way of being able to finish their studies on a limited budget , yet others saw Linux as a means of both being able to publish their doctoral thesis, ( in a less competitive arena) , and being able to defend their dissertation and thesis against a topic area that few of their professors and detractors were familiar with.

The interesting point is that now in the year of 2007 many of these former students are now in positions of importance and control in both many of the university computer programs and as well in important positions of responsibility and authority in I.T. departments of many leading and upcoming companies and institutions that often sets the computer and technology usage trends.

These now pioneers and adopters of the Linux Open Source computer operating system both are familiar and knowledgeable of the Linux O.S. . They both know the capabilities of Linux , how to modify for their computer needs and the situations and know the inherent advantages of Linux and the Open Source concepts.

Indeed given a choice they are more familiar with Linux than the mainstay Microsoft Windows or Microsoft Vista products.. Given their choices and druthers . Linux is both easier and preferable for them to work with for their client base.

Desktop Linux Users Numbers Continue to Grow

desktop linux users doubled

Some great news from desktop linux.com! They recently revealed the desktop survey results. The facts are there, the number of desktop linux users has doubled the last year!

And what is the desktop linux users distribution of choice? The Ubuntu family (Xubuntu, Kubuntu, Ubuntu, Ubuntu Studio, Edubuntu) leads on, and SuSe is the second runner up.

The survey shows us that more and more people are trying out a GNU/Linux distro, more and more people are getting aware that they can choose their OS. Up until Dell started to cooperate with Ubuntu, we had to accept that a PC you ordered came with a MS OS install (unless you bought parts and built your own pc).
