For example, I want to follow this guide on how to disable Brew analytics (under warning) but I have no idea how to find my environmental variables.
Most of the guides out there I found, such as this one, are all outdated; ~/.bash_profile
doesn't exist according to how the answer described it. Can some please explain to a new MacOS user how all this now works?
Please note my understanding of Unix-based filesystems are limited. Treat me as a noob.
