macOS command line tools

macOS comes with a Terminal and can run UNIX command-line tools directly.

When you see $ in this tutorial, you should type into your shell the command that comes after the $.

Open terminal

Open the Terminal application which comes with macOS.

Install compiler

Install a compiler.

$ xcode-select --install

Notice that this compiler is really Apple LLVM pretending to be g++. Your version might be different.

$ g++ --version
Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 9.0.0 (clang-900.0.38)
Target: x86_64-apple-darwin16.7.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

Homebrew package manager

Install the Homebrew package manager.

$ /bin/bash -c "$(curl -fsSL"

Apple Silicon users (“M1”, “M2”, etc.) only - Homebrew installs to a non-standard location, /opt/homebrew/. You’ll need to run the following to add Homebrew to your path:

$ echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.zprofile

Close your terminal and reopen your terminal.

Check your install. Your version might be different.

$ brew --version
Homebrew 3.6.14

Install CLI tools

Use the Homebrew package manager to install a few command line programs.

$ brew install wget git tree

Use CLI tools

Now would be a great time to take a look at our CLI Tutorial.


CLI open file

Opens a file or directory with the default application, like a double click. See the open command in the CLI tutorial.
