I recently upgraded my Mac from 10.13 to 10.14 and I can't seem to find my Homebrew. /usr/local is practically empty; just MySQL remains. Does brew get removed after an OS upgrade? Should I install it from scratch? What about the packages I installed using homebrew on the older version?

You should run brew update and see what happens. If Homebrew refuses to run, reinstall it using the command at https://brew.sh.

You should then run brew upgrade to make sure you're running the latest packages. If brew list shows no packages, then it looks like you'll have to re-install these packages.

Tried. "brew update" threw a "command not found" error. I've reinstalled Homebrew and ended up reinstalling some other packages. What I'm not able to understand is how/why brew got removed on an OS upgrade when all my other installations and files are fine... :(

@PrateekDewan I do not know specifically why, but some parts of the system are reset by the system update
