brew(1) – The Missing Package Manager for macOS (or Linux)

SYNOPSIS

brew --version
brew command [--verbose|-v] [options] [formula] …

DESCRIPTION

Homebrew is the easiest and most flexible way to install the UNIX tools Apple didn’t include with macOS. It can also install software not packaged for your Linux distribution to your home directory without requiring sudo.

ESSENTIAL COMMANDS

For the full command list, see the COMMANDS section.

With --verbose or --debug, many commands print extra debugging information. Note that these options should only appear after a command.

install formula

Install formula.

formula is usually the name of the formula to install, but it has other syntaxes which are listed in the SPECIFYING FORMULAE section.

uninstall formula

Uninstall formula.

list

List all installed formulae.

search [text|/text/]

Perform a substring search of cask tokens and formula names for text. If text is flanked by slashes, it is interpreted as a regular expression. The search for text is extended online to homebrew/core and homebrew/cask. If no search term is provided, all locally available formulae are listed.

commands [options]

Show lists of built-in and external commands.

• -q, --quiet: List only the names of commands without category headers.

shellenv

Print export statements. When run in a shell, this installation of Homebrew will be added to your PATH, MANPATH, and INFOPATH.

The variables HOMEBREW_PREFIX, HOMEBREW_CELLAR and HOMEBREW_REPOSITORY are also exported to avoid querying them multiple times. Consider adding evaluation of this command’s output to your dotfiles (e.g. ~/.profile, ~/.bash_profile, or ~/.zprofile) with: eval $(brew shellenv)

tap [options] [user/repo] [URL]

Tap a formula repository.

If no arguments are provided, list all installed taps.

With URL unspecified, tap a formula repository from GitHub using HTTPS. Since so many taps are hosted on GitHub, this command is a shortcut for brew tap user/repo https://github.com/user/homebrew-repo.

With URL specified, tap a formula repository from anywhere, using any transport protocol that git(1) handles. The one-argument form of tap simplifies but also limits. This two-argument command makes no assumptions, so taps can be cloned from places other than GitHub and using protocols other than HTTPS, e.g. SSH, git, HTTP, FTP(S), rsync.

• --full: Convert a shallow clone to a full clone without untapping. Taps are only cloned as shallow clones if --shallow was originally passed.
• --shallow: Fetch tap as a shallow clone rather than a full clone. Useful for continuous integration.

• --formula: Treat all named arguments as formulae.
• --cask: Treat all named arguments as casks.

unlink [options] formula

Remove symlinks for formula from Homebrew’s prefix. This can be useful for temporarily disabling a formula: brew unlink formula && commands && brew link formula

• -n, --dry-run: List files which would be unlinked without actually unlinking or deleting any files.

unpin formula

Unpin formula, allowing them to be upgraded by brew upgrade formula. See also pin.

untap tap

Remove a tapped formula repository.

update [options]

Fetch the newest version of Homebrew and all formulae from GitHub using git(1) and perform any necessary migrations.

Fetch and reset Homebrew and all tap repositories (or any specified repository) using git(1) to their latest origin/master.

Note: this will destroy all your uncommitted or committed changes.

upgrade [options] [formula|cask]

Upgrade outdated casks and outdated, unpinned formulae using the same options they were originally installed with, plus any appended brew formula options. If cask or formula are specified, upgrade only the given cask or formula kegs (unless they are pinned; see pin, unpin).

If a version is specified, a best effort to determine the URL and SHA-256 or the tag and revision will be made if both values are not supplied by the user.

Note: this command cannot be used to transition a formula from a URL-and-SHA-256 style specification into a tag-and-revision style specification, nor vice versa. It must use whichever style specification the formula already uses.

• -n, --dry-run: Print what would be done rather than doing it.

• --no-fork: Don’t try to fork the repository.
• --mirror: Use the specified URL as a mirror URL. If URL is a comma-separated list of URLs, multiple mirrors will be added.
• --version: Use the specified version to override the value parsed from the URL or tag. Note that --version=0 can be used to delete an existing version override from a formula if it has become redundant.
• --message: Append message to the default pull request message.
• --url: Specify the URL for the new download. If a URL is specified, the SHA-256 checksum of the new download should also be specified.
• --sha256: Specify the SHA-256 checksum of the new download.
• --tag: Specify the new git commit tag for the formula.
• --revision: Specify the new git commit revision corresponding to the specified tag.
• -f, --force: Ignore duplicate open PRs. Remove all mirrors if --mirror was not specified.

OFFICIAL EXTERNAL COMMANDS

bundle [subcommand]

Bundler for non-Ruby dependencies from Homebrew, Homebrew Cask, Mac App Store and Whalebrew.

brew bundle [install]
Install and upgrade (by default) all dependencies from the Brewfile.

You can specify the Brewfile location using --file or by setting the HOMEBREW_BUNDLE_FILE environment variable.

You can skip the installation of dependencies by adding space-separated values to one or more of the following environment variables: HOMEBREW_BUNDLE_BREW_SKIP, HOMEBREW_BUNDLE_CASK_SKIP, HOMEBREW_BUNDLE_MAS_SKIP, HOMEBREW_BUNDLE_WHALEBREW_SKIP, HOMEBREW_BUNDLE_TAP_SKIP.

brew bundle will output a Brewfile.lock.json in the same directory as the Brewfile if all dependencies are installed successfully. This contains dependency and system status information which can be useful in debugging brew bundle failures and replicating a “last known good build” state. You can opt-out of this behaviour by setting the HOMEBREW_BUNDLE_NO_LOCK environment variable or passing the --no-lock option. You may wish to check this file into the same version control system as your Brewfile (or ensure your version control system ignores it if you’d prefer to rely on debugging information from a local machine).

brew bundle dump
Write all installed casks/formulae/images/taps into a Brewfile in the current directory.

brew bundle cleanup
Uninstall all dependencies not listed from the Brewfile.

This workflow is useful for maintainers or testers who regularly install lots of formulae.

brew bundle check
Check if all dependencies are installed from the Brewfile.

This provides a successful exit code if everything is up-to-date, making it useful for scripting.

brew bundle list
List all dependencies present in the Brewfile.

By default, only Homebrew dependencies are listed.

brew bundle exec command
Run an external command in an isolated build environment based on the Brewfile dependencies.

This sanitized build environment ignores unrequested dependencies, which makes sure that things you didn’t specify in your Brewfile won’t get picked up by commands like bundle install, npm install, etc. It will also add compiler flags which will help find keg-only dependencies like openssl, icu4c, etc.

• --file: Read the Brewfile from this location. Use --file=- to pipe to stdin/stdout.
• --global: Read the Brewfile from ~/.Brewfile.
• -v, --verbose: install prints output from commands as they are run. check lists all missing dependencies.
• --no-upgrade: install won’t run brew upgrade on outdated dependencies. Note they may still be upgraded by brew install if needed.
• -f, --force: dump overwrites an existing Brewfile. cleanup actually performs its cleanup operations.
• --cleanup: install performs cleanup operation, same as running cleanup --force.
• --no-lock: install won’t output a Brewfile.lock.json.
• --all: list all dependencies.
• --formula: list Homebrew dependencies.
• --cask: list Homebrew Cask dependencies.
• --tap: list tap dependencies.
• --mas: list Mac App Store dependencies.
• --whalebrew: list Whalebrew dependencies.
• --describe: dump adds a description comment above each line, unless the dependency does not have a description.
• --no-restart: dump does not add restart_service to formula lines.
• --zap: cleanup casks using the zap command instead of uninstall.

services [subcommand]

Manage background services with macOS’ launchctl(1) daemon manager.

If sudo is passed, operate on /Library/LaunchDaemons (started at boot). Otherwise, operate on ~/Library/LaunchAgents (started at login).

[sudo] brew services [list]
List all managed services for the current user (or root).

[sudo] brew services run (formula|--all)
Run the service formula without registering to launch at login (or boot).

[sudo] brew services start (formula|--all)

Stop the service formula immediately and unregister it from launching at login (or boot).

[sudo] brew services restart (formula|--all)
Stop (if necessary) and start the service formula immediately and register it to launch at login (or boot).

[sudo] brew services cleanup
Remove all unused services.

• --all: Run subcommand on all services.

test-bot [options] [formula]

Tests the full lifecycle of a Homebrew change to a tap (Git repository). For example, for a GitHub Actions pull request that changes a formula brew test-bot will ensure the system is cleaned and set up to test the formula, install the formula, run various tests and checks on it, bottle (package) the binaries and test formulae that depend on it to ensure they aren’t broken by these changes.

Only supports GitHub Actions as a CI provider. This is because Homebrew uses GitHub Actions and it’s freely available for public and private use with macOS and Linux workers.

• --dry-run: Print what would be done rather than doing it.
• --cleanup: Clean all state from the Homebrew directory. Use with care!
• --skip-setup: Don’t check if the local system is set up correctly.

• --tap: Use the Git repository of the given tap. Defaults to the core tap for syntax checking.
• --fail-fast: Immediately exit on a failing step.
• -v, --verbose: Print test step output in real time. Has the side effect of passing output as raw bytes instead of re-encoding in UTF-8.
• --test-default-formula: Use a default testing formula when not building a tap and no other formulae are specified.
• --bintray-org: Upload bottles to the given Bintray organisation.

• --only-tap-syntax: Only run the tap syntax check step.
• --only-formulae: Only run the formulae steps.
• --only-cleanup-after: Only run the post-cleanup step. Needs --cleanup.

CUSTOM EXTERNAL COMMANDS

Homebrew, like git(1), supports external commands. These are executable scripts that reside somewhere in the PATH, named brew-cmdname or brew-cmdname.rb, which can be invoked like brew cmdname. This allows you to create your own commands without modifying Homebrew’s internals.

Instructions for creating your own commands can be found in the docs: https://docs.brew.sh/External-Commands

SPECIFYING FORMULAE

Many Homebrew commands accept one or more formula arguments. These arguments can take several different forms:

• The name of a formula: e.g. git, node, wget.

• The fully-qualified name of a tapped formula: Sometimes a formula from a tapped repository may conflict with one in homebrew/core. You can still access these formulae by using a special syntax, e.g. homebrew/dupes/vim or homebrew/versions/node4.

• An arbitrary file: Homebrew can install formulae from a local path. It can point to either a formula file or a bottle.

SPECIFYING CASKS

Many Homebrew Cask commands accept one or more cask arguments. These can be specified the same way as the formula arguments described in SPECIFYING FORMULAE above.

ENVIRONMENT

Note that environment variables must have a value set to be detected. For example, run export HOMEBREW_NO_INSECURE_REDIRECT=1 rather than just export HOMEBREW_NO_INSECURE_REDIRECT.

• HOMEBREW_ARCH
  Linux only: Pass this value to a type name representing the compiler’s -march option.

  Default: native.

• HOMEBREW_ARTIFACT_DOMAIN
  Prefix all download URLs, including those for bottles, with this variable. For example, HOMEBREW_ARTIFACT_DOMAIN=http://localhost:8080 will cause a formula with the URL https://example.com/foo.tar.gz to instead download from http://localhost:8080/example.com/foo.tar.gz.

• HOMEBREW_AUTO_UPDATE_SECS
  Automatically check for updates once per this seconds interval.

  Default: 300.

  Use this URL as the download mirror for bottles. For example, HOMEBREW_BOTTLE_DOMAIN=http://localhost:8080 will cause all bottles to download from the prefix http://localhost:8080/.

  Default: macOS: https://homebrew.bintray.com/, Linux: https://linuxbrew.bintray.com/.

• HOMEBREW_BREW_GIT_REMOTE
  Use this URL as the Homebrew/brew git(1) remote.

  Default: https://github.com/Homebrew/brew.

• HOMEBREW_BROWSER
  Use this as the browser when opening project homepages.

  Default: $BROWSER or the OS’s default browser.

  export HOMEBREW_CASK_OPTS="--appdir=~/Applications --fontdir=/Library/Fonts"

• HOMEBREW_CLEANUP_MAX_AGE_DAYS
  Cleanup all cached files older than this many days.

  Default: 120.

• HOMEBREW_DISPLAY_INSTALL_TIMES
  If set, print install times for each formula at the end of the run.

• HOMEBREW_EDITOR
  Use this editor when editing a single formula, or several formulae in the same directory.

• HOMEBREW_FAIL_LOG_LINES
  Output this many lines of output on formula system failures.

  Default: 15.

• HOMEBREW_FORBIDDEN_LICENSES

• HOMEBREW_GITHUB_API_TOKEN
  Use this personal access token for the GitHub API, for features such as brew search. You can create one at https://github.com/settings/tokens. If set, GitHub will allow you a greater number of API requests. For more information, see: https://docs.github.com/en/rest/overview/resources-in-the-rest-api#rate-limiting

  Note: Homebrew doesn’t require permissions for any of the scopes, but some developer commands may require additional permissions.

• HOMEBREW_GITHUB_API_USERNAME
  Use this username for authentication with the GitHub API, for features such as brew search. This is deprecated in favour of using HOMEBREW_GITHUB_API_TOKEN.

• HOMEBREW_GIT_EMAIL
  Set the Git author and committer email to this value.

• HOMEBREW_GIT_NAME
  Set the Git author and committer name to this value.

• HOMEBREW_INSTALL_BADGE
  Print this text before the installation summary of each successful build.

  Default: The “Beer Mug” emoji.

• HOMEBREW_LIVECHECK_WATCHLIST
  Consult this file for the list of formulae to check by default when no formula argument is passed to brew livecheck.

  Default: $HOME/.brew_livecheck_watchlist.

• HOMEBREW_LOGS
  Use this directory to store log files.

  Default: macOS: $HOME/Library/Logs/Homebrew, Linux: $XDG_CACHE_HOME/Homebrew/Logs or $HOME/.cache/Homebrew/Logs.

• HOMEBREW_MAKE_JOBS
  Use this value as the number of parallel jobs to run when building with make(1).

  Default: The number of available CPU cores.

• HOMEBREW_NO_ANALYTICS
  If set, do not send analytics. For more information, see: https://docs.brew.sh/Analytics

• HOMEBREW_NO_AUTO_UPDATE
  If set, do not automatically update before running brew install, brew upgrade or brew tap.

• HOMEBREW_NO_BOTTLE_SOURCE_FALLBACK
  If set, fail on the failure of installation from a bottle rather than falling back to building from source.

• HOMEBREW_NO_INSTALLED_DEPENDENTS_CHECK
  If set, do not check for broken dependents after installing, upgrading or reinstalling formulae.

• HOMEBREW_NO_COLOR
  If set, do not print text with colour added.

  Default: $NO_COLOR.

• HOMEBREW_NO_COMPAT
  If set, disable all use of legacy compatibility code.

• HOMEBREW_NO_EMOJI
  If set, do not print HOMEBREW_INSTALL_BADGE on a successful build.

  Note: Will only try to print emoji on OS X Lion or newer.

• HOMEBREW_NO_GITHUB_API
  If set, do not use the GitHub API, e.g. for searches or fetching relevant issues after a failed install.

• HOMEBREW_NO_INSECURE_REDIRECT
  If set, forbid redirects from secure HTTPS to insecure HTTP.

  Note: While ensuring your downloads are fully secure, this is likely to cause from-source SourceForge, some GNU & GNOME-hosted formulae to fail to download.

• HOMEBREW_NO_INSTALL_CLEANUP
  If set, brew install, brew upgrade and brew reinstall will never automatically cleanup installed/upgraded/reinstalled formulae or all formulae every 30 days.

• HOMEBREW_PRY
  If set, use Pry for the brew irb command.

• HOMEBREW_SKIP_OR_LATER_BOTTLES
  If set along with HOMEBREW_DEVELOPER, do not use bottles from older versions of macOS. This is useful in development on new macOS versions.

• HOMEBREW_SORBET_RUNTIME
  If set, enable runtime typechecking using Sorbet.

• HOMEBREW_SVN
  Use this as the svn(1) binary.

  Default: A Homebrew-built Subversion (if installed), or the system-provided binary.

• HOMEBREW_TEMP
  Use this path as the temporary directory for building packages. Changing this may be needed if your system temporary directory and Homebrew prefix are on different volumes, as macOS has trouble moving symlinks across volumes when the target does not yet exist. This issue typically occurs when using FileVault or custom SSD configurations.

  Default: macOS: /private/tmp, Linux: /tmp.

• HOMEBREW_UPDATE_REPORT_ONLY_INSTALLED
  If set, brew update only lists updates to installed software.

• HOMEBREW_UPDATE_TO_TAG
  If set, always use the latest stable tag (even if developer commands have been run).

• HOMEBREW_VERBOSE
  If set, always assume --verbose when running commands.

• HOMEBREW_DEBUG
  If set, always assume --debug when running commands.

• HOMEBREW_VERBOSE_USING_DOTS
  If set, verbose output will print a . no more than once a minute. This can be useful to avoid long-running Homebrew commands being killed due to no output.

• all_proxy
  Use this SOCKS5 proxy for curl(1), git(1) and svn(1) when downloading through Homebrew.

• ftp_proxy
  Use this FTP proxy for curl(1), git(1) and svn(1) when downloading through Homebrew.

• http_proxy
  Use this HTTP proxy for curl(1), git(1) and svn(1) when downloading through Homebrew.

• https_proxy
  Use this HTTPS proxy for curl(1), git(1) and svn(1) when downloading through Homebrew.

• no_proxy
  A comma-separated list of hostnames and domain names excluded from proxying by curl(1), git(1) and svn(1) when downloading through Homebrew.

• SUDO_ASKPASS
  If set, pass the -A option when calling sudo(8).

USING HOMEBREW BEHIND A PROXY

Set the http_proxy, https_proxy, all_proxy, ftp_proxy and/or no_proxy environment variables documented above.

For example, to use an unauthenticated HTTP or SOCKS5 proxy:

export http_proxy=http://$HOST:$PORT

export all_proxy=socks5://$HOST:$PORT

And for an authenticated HTTP proxy:

export http_proxy=http://$USER:$PASSWORD@$HOST:$PORT
