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.

Depends on the delimiter too! For anyone else reading this, sed accepts many kinds of delimiters.
sed "s@thing@thing2@g" file.txtis valid. I use this sometimes when parsing/replacing text with lots of slashes (like directory lists) so I can avoid escaping a ton of stuff.I know, but it is not the case I was talking about. I meant widely used commands like
awk '{print $2}'that can be replaced withcut -f2.I know you know, as you already demonstrated your higher understanding. I just wanted to add a little bonus trick for anyone reading that doesn't know, and is learning from your examples.
the two are valid and no one is more correct than the other sooo...
