brew(1) -- The Missing Package Manager for macOS

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.

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

analytics [subcommand]

Control Homebrew's anonymous aggregate user behaviour analytics. Read more at https://docs.brew.sh/Analytics.

brew analytics [state]: Display the current state of Homebrew's analytics.

brew analytics [on|off]: Turn Homebrew's analytics on or off respectively.

brew analytics regenerate-uuid: Regenerate the UUID used for Homebrew's analytics.

cleanup [options] [formula|cask]

Remove stale lock files and outdated downloads for all formulae and casks, and remove old versions of installed formulae. If arguments are specified, only do this for the given formulae and casks. Removes all downloads more than 120 days old. This can be adjusted with HOMEBREW_CLEANUP_MAX_AGE_DAYS.

• --prune: Remove all cache files older than specified days.
• -n, --dry-run: Show what would be removed, but do not actually remove anything.
• -s: Scrub the cache, including downloads for even the latest versions. Note downloads for any installed formulae or casks will still not be deleted. If you want to delete those too: rm -rf "$(brew --cache)"
• --prune-prefix: Only prune the symlinks and directories from the prefix and remove no other files.

commands [options]

Show lists of built-in and external commands.

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

config

Show Homebrew and system configuration info useful for debugging. If you file a bug report, you will be required to provide this information.

deps [options] [formula]

Show dependencies for formula. Additional options specific to formula may be appended to the command. When given multiple formula arguments, show the intersection of dependencies for each formula.

• -n: Sort dependencies in topological order.
• --1: Only show dependencies one level down, instead of recursing.
• --union: Show the union of dependencies for multiple formula, instead of the intersection.
• --full-name: List dependencies by their full name.
• --include-build: Include :build dependencies for formula.
• --include-optional: Include :optional dependencies for formula.
• --include-test: Include :test dependencies for formula (non-recursive).
• --skip-recommended: Skip :recommended dependencies for formula.
• --include-requirements: Include requirements in addition to dependencies for formula.
• --tree: Show dependencies as a tree. When given multiple formula arguments, show individual trees for each formula.
• --annotate: Mark any build, test, optional, or recommended dependencies as such in the output.
• --installed: List dependencies for formulae that are currently installed. If formula is specified, list only its dependencies that are currently installed.
• --all: List dependencies for all available formulae.
• --for-each: Switch into the mode used by the --all option, but only list dependencies for each provided formula, one formula per line. This is used for debugging the --installed/--all display mode.

desc [options] (text|/text/|formula)

Display formula's name and one-line description. Formula descriptions are cached; the cache is created on the first search, making that search slower than subsequent ones.

• -s, --search: Search both names and descriptions for text. If text is flanked by slashes, it is interpreted as a regular expression.
• -n, --name: Search just names for text. If text is flanked by slashes, it is interpreted as a regular expression.
• -d, --description: Search just descriptions for text. If text is flanked by slashes, it is interpreted as a regular expression.

doctor [options]

Check your system for potential problems. Will exit with a non-zero status if any potential problems are found. 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.

• --list-checks: List all audit methods, which can be run individually if provided as arguments.
• -D, --audit-debug: Enable debugging and profiling of audit methods.

fetch [options] formula

Download a bottle (if available) or source packages for formula. For tarballs, also print SHA-256 checksums.

• --deps: Also download dependencies for any listed formula.
• -s, --build-from-source: Download source packages rather than a bottle.
• --build-bottle: Download source packages (for eventual bottling) rather than a bottle.
• --force-bottle: Download a bottle if it exists for the current or newest version of macOS, even if it would not be used during installation.

• --with-hostname: Include the hostname in the Gist.
• -n, --new-issue: Automatically create a new issue in the appropriate GitHub repository after creating the Gist.
• -p, --private: The Gist will be marked private and will not appear in listings but will be accessible with its link.

• -d, --debug: If brewing fails, open an interactive debugging session with access to IRB or a shell inside the temporary build directory.
• --env: If std is passed, use the standard build environment instead of superenv. If super is passed, use superenv even if the formula specifies the standard build environment.
• --ignore-dependencies: An unsupported Homebrew development flag to skip installing any dependencies of any kind. If the dependencies are not already present, the formula will have issues. If you're not developing Homebrew, consider adjusting your PATH rather than using this flag.

• --devel: If formula defines it, install the development version.
• --HEAD: If formula defines it, install the HEAD version, aka. master, trunk, unstable.
• --fetch-HEAD: Fetch the upstream repository to detect if the HEAD installation of the formula is outdated. Otherwise, the repository's HEAD will only be checked for updates when a new stable or development version has been released.
• --keep-tmp: Retain the temporary files created during installation.
• --build-bottle: Prepare the formula for eventual bottling during installation, skipping any post-install steps.
• --bottle-arch: Optimise bottles for the specified architecture rather than the oldest architecture supported by the version of macOS the bottles are built on.
• -f, --force: Install without checking for previously installed keg-only or non-migrated versions.
• -v, --verbose: Print the verification and postinstall steps.
• --display-times: Print install times for each formula at the end of the run.
• -i, --interactive: Download and patch formula, then open a shell. This allows the user to run ./configure --help and otherwise determine how to turn the software package into a Homebrew package.
• -g, --git: Create a Git repository, useful for creating patches to the software.

leaves

List installed formulae that are not dependencies of another installed formula.

• --overwrite: Delete files that already exist in the prefix while linking.
• -n, --dry-run: List files which would be linked or deleted by brew link --overwrite without actually linking or deleting any files.
• -f, --force: Allow keg-only formulae to be linked.

list, ls [options] [formula]

List all installed formulae.

If formula is provided, summarise the paths within its current keg.

• --aliases: Verify any alias symlinks in each tap.
• --syntax: Syntax-check all of Homebrew's Ruby files (if no *tap* is passed).

reinstall [options] formula

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)

switch formula version

Symlink all of the specified version of formula's installation into Homebrew's prefix.

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 on continuous integration, or if --shallow was originally passed.
• --shallow: Fetch tap as a shallow clone rather than a full clone. Useful for continuous integration.
• --force-auto-update: Auto-update tap even if it is not hosted on GitHub. By default, only taps hosted on GitHub are auto-updated (for performance reasons).
• --repair: Migrate tapped formulae from symlink-based to directory-based structure.
• --list-pinned: List all pinned taps.

tap-info [options] [tap]

Show detailed information about one or more *tap*s.

If no tap names are provided, display brief statistics for all installed taps.

• --installed: Show information on each installed tap.
• --json: Print a JSON representation of tap. Currently the default and only accepted value for version is v1. See the docs for examples of using the JSON output: https://docs.brew.sh/Querying-Brew

uninstall, rm, remove [options] formula

Uninstall formula.

• -f, --force: Delete all installed versions of formula.
• --ignore-dependencies: Don't fail uninstall, even if formula is a dependency of any installed formulae.

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.

• --merge: Use git merge to apply updates (rather than git rebase).
• --preinstall: Run on auto-updates (e.g. before brew install). Skips some slower steps.

update-reset [repository]

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]

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

Unless HOMEBREW_NO_INSTALL_CLEANUP is set, brew cleanup will then be run for the upgraded formulae or, every 30 days, for all formulae.

• -d, --debug: If brewing fails, open an interactive debugging session with access to IRB or a shell inside the temporary build directory.
• -s, --build-from-source: Compile formula from source even if a bottle is available.

• --force-bottle: Install from a bottle if it exists for the current or newest version of macOS, even if it would not normally be used for installation.
• --fetch-HEAD: Fetch the upstream repository to detect if the HEAD installation of the formula is outdated. Otherwise, the repository's HEAD will only be checked for updates when a new stable or development version has been released.
• --ignore-pinned: Set a successful exit status even if pinned formulae are not upgraded.
• --keep-tmp: Retain the temporary files created during installation.
• -f, --force: Install without checking for previously installed keg-only or non-migrated versions.
• -v, --verbose: Print the verification and postinstall steps.
• --display-times: Print install times for each formula at the end of the run.
• -n, --dry-run: Show what would be upgraded, but do not actually upgrade anything.
• --greedy: Upgrade casks with auto_updates or version :latest

bump-formula-pr [options] [formula]

Create a pull request to update formula with a new URL or a new tag.

If a URL is specified, the SHA-256 checksum of the new download should also be specified. A best effort to determine the SHA-256 and formula name will be made if either or both values are not supplied by the user.

If a tag is specified, the Git commit revision corresponding to that tag should also be specified. A best effort to determine the revision will be made if the value is not supplied by the user.

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.
• --write: When passed along with --dry-run, perform a not-so-dry run by making the expected file modifications but not taking any Git actions.

• --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.

Create a commit to increment the revision of formula. If no revision is present, "revision 1" will be added.

• -n, --dry-run: Print what would be done rather than doing it.
• --message: Append message to the default commit message.

cat formula

Display the source of formula.

command cmd

Display the path to the file being used when invoking brew cmd.

create [options] URL

Generate a formula for the downloadable file at URL and open it in the editor. Homebrew will attempt to automatically derive the formula name and version, but if it fails, you'll have to make your own template. The wget formula serves as a simple example. For the complete API, see: https://rubydoc.brew.sh/Formula

• --fail-if-changed: Return a failing status code if changes are detected in the manpage outputs. This can be used to notify CI when the manpages are out of date. Additionally, the date used in new manpages will match those in the existing manpages (to allow comparison without factoring in the date).
• --link: This is now done automatically by brew update.

pr-automerge [options]

Find pull requests that can be automatically merged using brew pr-publish.

ruby (-e text|file)

Run a Ruby instance with Homebrew's libraries loaded, e.g. brew ruby -e "puts :gcc.f.deps" or brew ruby script.rb.

• -r: Load a library using require.
• -e: Execute the given text string as a script.

sh [options]

Start a Homebrew build environment shell. Uses our years-battle-hardened Homebrew build logic to help your ./configure && make && make install or even your gem install succeed.

OFFICIAL EXTERNAL COMMANDS

cask subcommand

Install macOS applications distributed as binaries. See brew-cask(1).

Homebrew/homebrew-cask: https://github.com/Homebrew/homebrew-cask

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 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.

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 a 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.
• --no-lock: install won't output a Brewfile.lock.json.
• --all: list all dependencies.
• --brews: list Homebrew dependencies.
• --casks: list Homebrew Cask dependencies.
• --taps: 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): Start the service formula immediately and register it to launch at login (or boot).

[sudo] brew services stop (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 setup 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.
• --keep-old: run brew bottle --keep-old to build new bottles for a single platform.
• --skip-relocation: run brew bottle --skip-relocation to build new bottles that don't require relocation.
• --local: ask Homebrew to write verbose logs under ./logs/ and set $HOME to ./home/
• --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 to the given Bintray organisation.
• --root-url: use the specified URL as the root of the bottle's URL instead of Homebrew's default.
• --git-name: set the Git author/committer names to the given name.
• --git-email: set the Git author/committer email to the given email.
• --ci-upload: use the Homebrew CI bottle upload options.
• --publish: publish the uploaded bottles.
• --skip-recursive-dependents: only test the direct dependents.
• --only-cleanup-before: Only run the pre-cleanup step. Needs --cleanup.
• --only-setup: Only run the local system setup check step.
• --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.

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 the set 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.

• HOMEBREW_BAT: If set, use bat for the brew cat command.

• HOMEBREW_BAT_CONFIG_PATH: Use the bat configuration file. For example, HOMEBREW_BAT=$HOME/.bat/config.

  Default: $HOME/.bat/config

• HOMEBREW_BINTRAY_KEY: Use this API key when accessing the Bintray API (where bottles are stored).

• HOMEBREW_BINTRAY_USER: Use this username when accessing the Bintray API (where bottles are stored).

• HOMEBREW_BOTTLE_DOMAIN: Use the specified 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 the specified URL as the Homebrew/brew git(1) remote.

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

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

• HOMEBREW_CACHE: Use the specified directory as the download cache.

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

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

  Default: 120.

• HOMEBREW_COLOR: If set, force colour output on non-TTY outputs.

• HOMEBREW_CORE_GIT_REMOTE: Use the specified URL as the Homebrew/homebrew-core git(1) remote.

  Default: macOS: https://github.com/Homebrew/homebrew-core, Linux: https://github.com/Homebrew/linuxbrew-core.

• HOMEBREW_CURLRC: If set, do not pass --disable when invoking curl(1), which disables the use of curlrc.

• HOMEBREW_CURL_RETRIES: Pass the given retry count to --retry when invoking curl(1).

  Default: 3.

• HOMEBREW_CURL_VERBOSE: If set, pass --verbose when invoking curl(1).

• HOMEBREW_DEVELOPER: If set, tweak behaviour to be more relevant for Homebrew developers (active or budding) by e.g. turning warnings into errors.

• HOMEBREW_DISABLE_LOAD_FORMULA: If set, refuse to load formulae. This is useful when formulae are not trusted (such as in pull requests).

• HOMEBREW_DISPLAY: Use this X11 display when opening a page in a browser, for example with brew home. Primarily useful on Linux.

  Default: $DISPLAY.

• 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.

  Note: brew edit will open all of Homebrew as discontinuous files and directories. Visual Studio Code can handle this correctly in project mode, but many editors will do strange things in this case.

  Default: $EDITOR or $VISUAL.

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

  Default: 15.

• HOMEBREW_FORBIDDEN_LICENSES: A space-separated list of licenses. Homebrew will refuse to install a formula if that formula or any of its dependencies has a license on this list.

• HOMEBREW_FORCE_BREWED_CURL: If set, always use a Homebrew-installed curl(1) rather than the system version. Automatically set if the system version of curl is too old.

• HOMEBREW_FORCE_HOMEBREW_ON_LINUX: If set, running Homebrew on Linux will use URLs for macOS. This is useful when merging pull requests for macOS while on Linux.

• HOMEBREW_FORCE_VENDOR_RUBY: If set, always use Homebrew's vendored, relocatable Ruby version even if the system version of Ruby is new enough.

• HOMEBREW_GITHUB_API_PASSWORD: Use this password for authentication with the GitHub API, for features such as brew search. We strongly recommend using HOMEBREW_GITHUB_API_TOKEN instead.

• 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://developer.github.com/v3/#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. We strongly recommend using HOMEBREW_GITHUB_API_TOKEN instead.

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

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

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

  Default: The "Beer Mug" emoji.

• 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_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: Only tries 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 on 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 based 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 with HOMEBREW_DEVELOPER, do not use bottles from older versions of macOS. This is useful in development on new macOS versions.

• 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_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_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.

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
