How to reveal dot files in finder?

Here’s one from my archives. To reveal dot files in macOS Finder, open your Terminal (/Applications/Utilities) application and then enter,

defaults write com.apple.finder AppleShowAllFiles YES

Then restart Finder by holding down Option and Control, or right-clicking on the Finder’s icon in your Dock and choosing “Relaunch”.

To revert this behavior, simply change the YES to NO in that defaults command.
