    linux Author: Aaron PetersTags: , Comments: 4Published: Nov 30, 2016

    Shell scripts are incredibly useful things. They allow you to do something as basic as creating an easy command to replace a more difficult one with lots of flags, to batching up many complex commands to run from a cron job. They’re great because you can quickly fire them off in your favorite terminal, but in some cases they require you to remember specific combinations of flags or options.

Linux - free and open source operating system

Linux is a unix-like operating system kernel initially released by Linus Torvalds in 1991. The kernel was released under the GPL license in order to be used with the operating system of the GNU Project as GNU Hurd that was the project's kernel wasn't available at the time. That led to the creation of the GNU/Linux OS and shortly after the word Linux alone was used to indicate the operating system and not only the kernel. Linux as a kernel project, enjoyed a constant rise of contributions from a growing number of developers since the very early days of its low functionality, mostly thanks to its open source nature and the rise of the internet. Linux nowadays powers personal computers, mobile devices, embedded devices, servers and supercomputers.


What are the reasons to choose Linux?

First and foremost, Linux is free software and as such it allows its users the freedom to utilize it in any way that they see fit, without legislative limitations. Free software belongs to its users while proprietary software belongs to its creators who only sell or grant the permission to use their software and only for certain predefined purposes. Thanks to its nature and financial support from patreons and supporters, Linux as a kernel is distributed free of charge which is also the case for the vast majority of Linux distributions and free software applications.

Apart from the cost and legal benefits, Linux offers more choices to its users. There are literally numerous desktop environments, window managers, applications that serve the same or similar purposes, distributions and even themes to choose from. While this plethora of different options can become overwhelming for some new users, choice is what allows for high levels of customization that can transform an operating system to fit exactly the needs of a user, or a group of users.

Linux is also one of the most hardware friendly operating systems in the sense that it can run in most devices out there. Although closed source hardware was difficult to support during the first years of Linux, the tables have now turned mostly thanks to the support from large hardware and software vendors such as IBM, Google and Intel. Linux can even revive old hardware that would otherwise sit uselessly in a dusty corner.

Last but not least, Linux boasts high levels of security and performance as an operating system, making it ideal for use in servers, scientific supercomputers, aerospace applications, governmental and military networks, and enterprise environments.
