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'm not expert in sed or awk. I always have to Google. For me though, it's generally that you can do a great deal in just one line of awk or sed. They're standard on any Linux distribution I've ever used. When building out pipelines, scripts that you want run from an installer you built post install and when removing, sed and awk rather than needing python.
All really nice when you have strict configuration management and versioning and there's something deployed but it doesn't have the python packages installed that would make it easy in python and you can't just pip install it on hundreds+ of computers without going through a process of approval and building a new tagged version release but sed/awk/etc can do the job. If it's hard enough, python and whatever packages you can install. If simple enough to do in a small bash script, no python just what's standard in your Linux distro
