what is ~ linux
Linux is an operating system, a large piece of software that manages a computer. It is similar to Microsoft Windows, but it is entirely free. The accurate name is GNU/Linux but Linux is used more often. Linux is not one company's product, but a number of companies and groups of people contribute to it. In fact, the GNU/Linux system is a core component, which is branched off into many different products. They are called distributions. Distributions change the appearance and function of Linux completely.
