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.

Thinking about it some more I am not sure that we would have to go that far. Well not in the longer term - short term we might for experimenting with ideas. I think one of the bigger problems ATM is the terminal does not understand what a shell is or its component parts. Terminals just display characters and move the cursor around the screen and send keyboard and now mouse input back to the command they run. They are also aware of alternative buffers and raw input mode and know about echoing characters back the the screen.
If we extended the terminals to also understand some shell concepts like the prompt, commands being typed and output from the commands and gave the shell some markers it could send along with these (like we do with color information ATM) the terminal would be able to use these to change how it displays each part and would open up a lot of new an interesting features. Could even add things like tooltip support or actions on clicking some bits of the text.
I am starting to see these terminals as experimenting on what we features could be enabled if we were not stuck on the current VT100 protocals. Though if we ever get wider adoption and generalisation of these ideas backed back into the protocals will be another question to consider.
