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.

If you have any suggestions or criticisms, feel free to comment them.

Being plain text, it's much easier to read on a wide screen, or on something without line wrapping.

At the end, in redirection, <<: that's not how here-documents work. The example gives the impression it will read the given file up until "STOP", but in reality the shell expects you to keep writing your here-doc until you write "STOP" and then feeds it to the program as if it were all on stdin. I don't think wc even does anything with the stdin if you give it a filename... Note that variable expansion will happen in here-docs, so it's a bit different than a simple cat. Also look into here-strings. And process substitution, I find that quite handy.
