By default, Homebrew will install all packages in the directory /usr/local/Cellar/, and also creates symbolic links at /usr/local/opt/ and /usr/local/bin/ (for executable files).

Terminal


/usr/local/Cellar/
/usr/local/opt/
/usr/local/bin/

Terminal


% brew -v
Homebrew 2.7.2
Homebrew/homebrew-core (git revision 3c379; last commit 2021-01-11)
Homebrew/homebrew-cask (git revision 40d45; last commit 2021-01-11)

P.S Tested with Homebrew 2.7.2 and macOS Big Sur 11.1

4. brew info [package]

We can use brew info [package] to show detail about a specified installed package.

brew info nginx
For example, the below command shows the detail about the brew install nginx package.

Terminal


% brew info nginx      

nginx: stable 1.19.6 (bottled), HEAD
HTTP(S) server and reverse proxy, and IMAP/POP3 proxy server
https://nginx.org/
/usr/local/Cellar/nginx/1.17.9 (28 files, 2.1MB) *
  Poured from bottle on 2020-04-11 at 19:59:27
From: https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/nginx.rb
License: BSD-2-Clause
==> Dependencies
Required: [email protected] ✘, pcre ✔
==> Options
--HEAD
	Install HEAD version
==> Caveats
Docroot is: /usr/local/var/www

The default port has been set in /usr/local/etc/nginx/nginx.conf to 8080 so that
nginx can run without sudo.

nginx will load all files in /usr/local/etc/nginx/servers/.

To have launchd start nginx now and restart at login:
  brew services start nginx
Or, if you don't want/need a background service you can just run:
  nginx

brew info maven
Below is another example to show the detail about the brew install maven package.

Terminal


% brew info maven

maven: stable 3.6.3
Java-based project management
https://maven.apache.org/
Conflicts with:
  mvnvm (because also installs a 'mvn' executable)
/usr/local/Cellar/maven/3.6.3_1 (87 files, 10.7MB) *

This is not correct for macOS Monterey 12.6. There is no /usr/local/Cellar after a brew installation.

Are you using an M1/M2 mac?

Ventura and I presume Monterey have /opt/homebrew/Cellar

Agreed – this works on macOS Ventura – instead of what you have in (1) above:

ls -lsa /opt/homebrew/Cellar

I’m using macOS Ventura, the path is still on /usr/local/Cellar.
