Using different paths for M1 or Intel processor

[robertobermejo]

As you can see in the Brew.sh documentation, there are different paths depending on the Mac's processor.

This script installs Homebrew to its preferred prefix (/usr/local for macOS Intel, /opt/homebrew for Apple Silicon and /home/linuxbrew/.linuxbrew for Linux) so that you don’t need sudo when you brew install. It is a careful script; it can be run even if you have stuff installed in the preferred prefix already. It tells you exactly what it will do before it does it too. You have to confirm everything it will do before it starts.

The best approach is to use HOBREW_PREFIX env or get the brew prefix by executing brew --prefix. You can see an example in this url where I have it fixed:

ZSH_BIN_PATH="$(brew --prefix zsh)"

You can get the prefix of installed packages with brew with brew --prefix <package>

But could happen that the command is being executed in a system without brew or installed in other way or with brew prefix not added but installed.
