If you are a Mac or a Linux user then homebrew (or simply called brew) is the most popular package manager that you will use on a day-to-day basis for installing tools and software that you will need for software development.
In this article I have tried to cover a list of commands that you should be aware of to make the best out of the brew.
1. --version Command
% brew --version
% brew -v
You can use either --version or -v to print out the version number of homebrew as well as homebrew-core and cask on the console.Example Output:
Homebrew 3.5.10 Homebrew/homebrew-core (git revision eb53464deb8; last commit 2022-09-04) Homebrew/homebrew-cask (git revision 40c8fdd23d; last commit 2022-09-04)
2. Brew Update Command
% brew update
This command should be used to update your installed brew version to the latest version from GitHub as well as to keep your formulae list up to date.
You may use the update command with a few useful options,
- -f, --force
- -q, --quiet
- -v, --verbose
- -d, --debug
3. Brew Doctor Command
% brew doctor
% brew dr
The doctor command is quite a useful one to know of any potential problems.Example:
% brew doctor Please note that these warnings are just used to help the Homebrew maintainers with debugging if you file an issue. If everything you use Homebrew for is working fine: please don't worry or file an issue; just ignore this. Thanks! Warning: You are using macOS 13. We do not provide support for this pre-release version. You will encounter build failures with some formulae. Please create pull requests instead of asking for help on Homebrew's GitHub, Twitter or any other official channels. You are responsible for resolving any issues you experience while you are running this pre-release version. Warning: Ruby version 2.6.10 is unsupported on macOS 13. Homebrew is developed and tested on Ruby 2.6.9, and may not work correctly on other Rubies. Patches are accepted as long as they don't cause breakage on supported Rubies. Warning: /usr/bin occurs before /opt/homebrew/bin in your PATH. This means that system-provided programs will be used instead of those provided by Homebrew. Consider setting your PATH so that /opt/homebrew/bin occurs before /usr/bin. Here is a one-liner: echo 'export PATH="/opt/homebrew/bin:$PATH"' >> ~/.zshrc The following tools exist at both paths: python3 pip3
4. Brew Help Command
The help command is the one that can help you quickly learn and understand brew commands and options.
% brew help Example usage: brew search TEXT|/REGEX/ brew info [FORMULA|CASK...] brew install FORMULA|CASK... brew update brew upgrade [FORMULA|CASK...] brew uninstall FORMULA|CASK... brew list [FORMULA|CASK...] Troubleshooting: brew config brew doctor brew install --verbose --debug FORMULA|CASK Contributing: brew create URL [--no-fetch] brew edit [FORMULA|CASK...] Further help: brew commands brew help [COMMAND] man brew https://docs.brew.s
% brew help --version Usage: brew --version, -v Print the version numbers of Homebrew, Homebrew/homebrew-core and Homebrew/homebrew-cask (if tapped) to standard output.
5. Search for formula
% brew search &l;formula-name>
6. List all Installed Formulae
% brew list
7. Install a formula
% brew install &l;formula-name>
8. Uninstall a formula
% brew uninstall &l;formula-name>
9. Find Outdated Formulae Command
10. Update Formulae Command
% brew upgrade <formula>
This command will upgrade outdated casks and formulae
% brew outdated
This command will list out outdated casks and formulae.
11. Pin and Unpin Formulae Command
% brew pin <formula>
% brew unpin <formula>
Pin to prevent the formula from being upgraded.
12. Get Information about a formula
% brew info <formula-name>
% brew cleanup --dry-run
The cleanup command with dry-run option will show what all outdated formulas will be cleaned up if you run the cleanup command if you do not want to clean a specific formula then you can pin it.Example:
% brew cleanup --dry-run Would remove (empty directory): /firstname.lastname@example.org/private Would remove (empty directory): /email@example.com/certs % brew cleanup Pruned 0 symbolic links and 2 directories from /opt/homebrew
