Homebrew builds and packages software using a Ruby- and CLI-based system, which is known as Homebrew/brew. Homebrew builds can occur locally at the user’s computer using Homebrew/brew directly, or remotely using a downloadable build server (Heroku).
When a Homebrew build is completed, the user can package and install the individual software packages and programs created in the build. Homebrew/brew is installed and run on Mac, Linux, and BSD systems, so the environment of Homebrew build depends on the user’s choice of operating system.
Generally, builds are written in Ruby, which can run on a wide range of systems. The user’s system and the build kits provided by Homebrew are used to provide the environment for home brew builds. This allows Homebrew to package and install large software solutions such as databases and web servers.
Additionally, the homebrew install instructions provide guidance to download compatible build kits, depending on the user’s operating system.
Where does Homebrew install packages on Mac?
Homebrew installs packages on Mac in the /usr/local/Cellar directory. Packages can be symlinked into the appropriate Library/Homebrew folder, which is Homebrew’s default behaviour. You can customize these locations by setting the appropriate environment variables (e. g.
HOMEBREW_CELLAR, HOMEBREW_PREFIX, HOMEBREW_REPOSITORY, etc. ) in your bash profile. Additionally, packages are installed via symbolic links from the /usr/local/bin directory under the prefix of the formula name.
For example, if you installed the mysql package, then the symbolic link will be at /usr/local/bin/mysql pointing to /usr/local/Cellar/mysql/[version]/bin/mysql.

For example, if you wanted to access the Homebrew Cellar from the command line, you could use the following command:
cd /usr/local/Cellar/
From here you can explore the contents of the Cellar and also view any installed binaries that have been placed there. If you wanted to access one of the binaries, you can use the ‘. /’ command. In order to access the binary with the name “example_binary”, you would use the following command:
