The Development of the Linux OS - The Linux Kernel "Project" - Linux OS Training

Linus Torvalds and the Development the Linux OS in the Linux Kernel "Project"

As fortune would have it, Finland had excellent Internet access in 1991 and Linus was able to use the Internet to enlist the assistance of other programmers from all over the world to help him with his project - the development of Linux (the Linux "kernel"). Linus let these software developers know that he was working on Linux and the ones that were interested in the project joined in! The first complete version of

Linux (which is the Linux kernel) became available in 1994.

Linus continues to work with other software developers to improve the Linux OS. The developers that have expertise in certain areas of kernel programming work on those areas of the Linux project. Thousands of developers have contributed to the over four million lines of text in the Linux kernel source code.

Once the kernel reaches a point where the developers believe that it has reached another level of maturity and should be released again, it becomes available for download - for Free - over the Internet. Thousands of people have downloaded the source code of the Linux kernel.

Once downloaded, they use a program called a compiler to “compile” (convert) the source code text into "executable" form, so that the OS will run on their systems.

Linux Training Tips: The source code of a program is the text of a program. It's the programming logic of the program, such as "if a = b then do step c" and this text is saved in a text file.

The text in the text file is just "plain text" and does not include any formatting, like bold or underline, or left and right margin settings. The source code of a program is "compiled" (processed) by a compiler program to create an executable program file that can be run on a computer system. So, the text of the Linux source code is compiled to create the Linux OS.

Many of the people that download the OS report back to Linus and the other kernel developers. They describe how well the software works, what they would like to see added, and they also identify any bugs that they have encountered. The developers are continuously revising the source code of the OS to fix bugs and create enhancements for it.

The source code for the Linux kernel is available via “ftp” (file transfer protocol) at ftp://ftp.funet.fi. The .fi at the end of this address stands for Finland.

One of the easiest and best methods of getting Linux training (online or on CD) is to actually see the Linux commands you need to know being run "live". And you can do this by watching Linux video tutorials. Where you get see and hear how a Linux command is run and then pause the video and do the steps to run the command yourself!
