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.

Been using it (not often beyond basics for home server container administration) for years but I always get confused with searching vs search and replace vs global search
/ (n for next instances)
:%s//
:g//p (grep was named after this one IIRC, Global Regular Expression Print)
And often I just use :%s to search and highlight all instances and don't press enter because I forget the others and I often have to search and replace for docker comppse snippets.
