How can you find the version of Linux you are using on your computer?
The best solution is this command (actually two in one): uname -a && cat /etc/*release The first part of the command tells you the version of the Linux kernel that is running. The second part of the command tells you the name of the distribution, like "Red Hat Enterprise Linux X.X". When asked this same question, most people only answer the first part, which is not always what the user needs to know.

What do you see when you first turn on a Linux system?
That depends on the hardware, the distribution, and what you are referring to by "first turn on." Most computers do not display anything at all for a brief period of time while the display is initialized. Depending on the system and how long it takes to initialize the hardware, you may also see a BIOS POST screen or a splash screen. Then, depending on how the bootloader is configured, the system may either load directly into Linux, or present a menu for a choice of operating systems. There are several bootloaders that can boot Linux, with a variety of appearances. Finally, when Linux itself begins loading, the appearance can vary tremendously, from a splash screen to a framebuffer console to a simple system console to no display at all.
