From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

My tip would be to try a few distros before you settle on one. Ubuntu was it for me about seven years ago, but I used mint for a few years and am using MX with xfce now.
Also,
sudo !!
is pretty useful when you forget tosudo
the previous command. It means "super user do the last command I just boneheadedly forgot to do that to"Also can use
!!
and do a space at any place to bring in last command. Not used much as you could just do an up arrow but helps if you edit around a lot and experimenting with a cli tool or command.Also,
!!
is a shortcut for!-1
so if you want the 2nd latest command you could do!-2
and so on.
