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.

I understand the mindset you have, but trust me, you'll learn (sooner or later) a habit to pause and check your command before hitting enter. For some it takes a bit longer and it'll bite you in the butt for few times (so have backups), but everyone has gone down that path and everyone has fixed their mistakes now and then. If you want hard (and fast) way to learn to confirm your commands, use dd a lot ;)
One way to make it a bit less scary is to 'mv /tmp' and when you confirmed that nothing extra got removed you can 'cd /tmp; rm -rf ', but that still includes the 'rm -rf' part.
