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 use awk all the time, nothing too fancy, but when you need to pull out elements of text it's usually way easier than using cut.
awk {' print $3 '} will pull the third element based on your IFS variable (internal field separater, default is whitespace)
awk {' print $NF '} gets you the last element, and awk {' print $(NF-1) '} gets you one element from the last, and so on.
Basic usage but so fast and easy for so many everyday command line things.
You can also add to the output. I use it frequently to pull a list of files, etc, from another file, and then do something like generate another script from that output. This is a weak example, but one I can think of off my head. Not firing up my work laptop to search for better examples until after the holidays. LOL.
awk {'print "ls -l "$1'}
And then send that to a file that I can then execute.
