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.

Just to add a bit more to this for the newbies who are using Arch (god help you).
Will write this list to a file, run without the '> packages.txt' if you just want to see the output and;
Will install all of the needed (i.e. not installed) packages from that list.
If you use
-Qeq, you should be able to skip the ask part of the command.TIL
Looks like I gave up on RTFM and turned to awk too early.
Just remember that you can easily generate a list of all explicitly installed packages. You'll figure out how exactly when you end up needing it.
This is how I do it. I'll see something and think 'hmm, interesting' and completely forget any of the details but I'll remember vaguely that something exists then I can search for it.
Language models are pretty good at solving the 'I think I remember something that does this specific thing but don't know where to look' kinds of problems (don't just blindly run LLM generated commands kids). Then once you have a lead, traditional searching is much easier.
