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.

Studying and awk came up.

Spent about an hour and I see some useful commands that extend past what "cut" can do. But really when dealing with printf() format statements is anyone using awk scripts for this?

Or is everyone just using their familiar scripting language. I'd reach for Python for the problems being presented as useful for awk.

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.
