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 without requiring sudo.
formula
: Homebrew package definition that builds from upstream sources
cask
: Homebrew package definition that installs macOS native applications
prefix
: path in which Homebrew is installed, e.g. /usr/local
keg
: installation destination directory of a given formula version, e.g.
/usr/local/Cellar/foo/0.1
rack
: directory containing one or more versioned kegs, e.g.
/usr/local/Cellar/foo
keg-only
: a formula is keg-only if it is not symlinked into Homebrew's prefix
opt prefix
: a symlink to the active version of a keg, e.g. /usr/local/opt/foo
Cellar
: directory containing one or more named racks, e.g. /usr/local/Cellar
Caskroom
: directory containing one or more named casks, e.g. /usr/local/Caskroom
external command
: brew subcommand defined outside of the Homebrew/brew GitHub repository
tap
: directory (and usually Git repository) of formulae, casks and/or external commands
bottle
: pre-built keg poured into a rack of the Cellar instead of building from upstream sources
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.
Some command behaviour can be customised with environment variables; see the ENVIRONMENT section.
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.
List all installed formulae.
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.

Valid shells: bash|csh|fish|pwsh|sh|tcsh|zsh
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. To help guarantee
idempotence, this command produces no output when Homebrew's bin and sbin
directories are first and second respectively in your PATH. Consider adding
evaluation of this command's output to your dotfiles (e.g. ~/.bash_profile or
~/.zprofile on macOS and ~/.bashrc or ~/.zshrc on Linux) with: eval "$(brew shellenv)"
The shell can be specified explicitly with a supported shell name parameter. Unknown shells will output POSIX exports.
Edit tab information for installed formulae or casks.
This can be useful when you want to control whether an installed formula should
be removed by brew autoremove. To prevent removal, mark the formula as
installed on request; to allow removal, mark the formula as not installed on
request.

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.
--custom-remote
: Install or change a tap with a custom remote. Useful for mirrors.
--repair

Bundler for non-Ruby dependencies from Homebrew, Homebrew Cask, Mac App Store, Whalebrew and Visual Studio Code.
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 for 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 present in the Brewfile.
This workflow is useful for maintainers or testers who regularly install lots of formulae.
Unless --force is passed, this returns a 1 exit code if anything would be
removed.
brew bundle check
: Check if all dependencies present in the Brewfile are installed.
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 formula 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 with finding 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 or the HOMEBREW_BUNDLE_FILE_GLOBAL
environment variable, if set.
-v, --verbose
: install prints output from commands as they are run. check lists all
missing dependencies.
--no-upgrade
: install does not run brew upgrade on outdated dependencies. Note they may
still be upgraded by brew install if needed.
-f, --force
: install runs with --force/--overwrite. dump overwrites an existing
Brewfile. cleanup actually performs its cleanup operations.
--cleanup
: install performs cleanup operation, same as running cleanup --force. This
is enabled by default if HOMEBREW_BUNDLE_INSTALL_CLEANUP is set and
--global is passed.
--no-lock
: install does not output a Brewfile.lock.json.
--all
: list all dependencies.
--formula
: list Homebrew formula dependencies.
--cask
: list Homebrew cask dependencies.
--tap
: list Homebrew tap dependencies.
--mas
: list Mac App Store dependencies.
--whalebrew
: list Whalebrew dependencies.
--vscode
: list VSCode extensions.
--describe
: dump adds a description comment above each line, unless the dependency does
not have a description. This is enabled by default if
HOMEBREW_BUNDLE_DUMP_DESCRIBE is set.
--no-restart
: dump does not add restart_service to formula lines.
--zap
: cleanup casks using the zap command instead of uninstall.
Print instructions for setting up the command-not-found hook for your shell. If the output is not to a tty, print the appropriate handler script for your shell.
Manage background services with macOS' launchctl(1) daemon manager or Linux's
systemctl(1) service manager.
If sudo is passed, operate on /Library/LaunchDaemons or
/usr/lib/systemd/system (started at boot). Otherwise, operate on
~/Library/LaunchAgents or ~/.config/systemd/user (started at login).
[sudo] brew services [list] (--json) (--debug)
: List information about all managed services for the current user (or root).
Provides more output from Homebrew and launchctl(1) or systemctl(1) if run
with --debug.
[sudo] brew services info (formula|--all|--json)
: 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).

: 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 kill (formula|--all)
: Stop the service formula immediately but keep it registered to launch 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.
--file
: Use the service file from this location to start the service.
--sudo-service-user
: When run as root on macOS, run the service(s) as this user.
--all
: Run subcommand on all services.
--json
: Output as JSON.
--no-wait
: Don't wait for stop to finish stopping the service.
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.

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
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/vimorhomebrew/versions/node4. -
An arbitrary file: Homebrew can install formulae from a local path. It can point to either a formula file or a bottle. Prefix relative paths with
./to prevent them from being interpreted as a formula or tap name.
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.
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_* environment variables can also be set in Homebrew's environment
files:
-
/etc/homebrew/brew.env(system-wide) -
$HOMEBREW_PREFIX/etc/homebrew/brew.env(prefix-specific) -
$XDG_CONFIG_HOME/homebrew/brew.envif$XDG_CONFIG_HOMEis set or$HOME/.homebrew/brew.envotherwise (user-specific)
User-specific environment files take precedence over prefix-specific files and
prefix-specific files take precedence over system-wide files (unless
HOMEBREW_SYSTEM_ENV_TAKES_PRIORITY is set, see below).
Note that these files do not support shell variable expansion e.g. $HOME or
command execution e.g. $(cat file).
HOMEBREW_ALLOWED_TAPS
: A space-separated list of taps. Homebrew will refuse to install a formula unless it and all of its dependencies are in an official tap or in a tap on this list.
HOMEBREW_API_AUTO_UPDATE_SECS
: Check Homebrew's API for new formulae or cask data every
HOMEBREW_API_AUTO_UPDATE_SECS seconds. Alternatively, disable API
auto-update checks entirely with HOMEBREW_NO_AUTO_UPDATE.
Default: 450.
HOMEBREW_API_DOMAIN
: Use this URL as the download mirror for Homebrew JSON API. If metadata files at that URL are temporarily unavailable, the default API domain will be used as a fallback mirror.
Default: https://formulae.brew.sh/api.
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 value. 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/https://example.com/foo.tar.gz. Bottle URLs however,
have their domain replaced with this prefix. This results in e.g.
https://ghcr.io/v2/homebrew/core/gettext/manifests/0.21 to instead be
downloaded from
http://localhost:8080/v2/homebrew/core/gettext/manifests/0.21
HOMEBREW_ARTIFACT_DOMAIN_NO_FALLBACK
: If HOMEBREW_ARTIFACT_DOMAIN and HOMEBREW_ARTIFACT_DOMAIN_NO_FALLBACK are
both set, if the request to HOMEBREW_ARTIFACT_DOMAIN fails then it Homebrew
will error rather than trying any other/default URLs.
HOMEBREW_AUTO_UPDATE_SECS
: Run brew update once every HOMEBREW_AUTO_UPDATE_SECS seconds before some
commands, e.g. brew install, brew upgrade and brew tap. Alternatively,
disable auto-update entirely with HOMEBREW_NO_AUTO_UPDATE.
Default: 86400 (24 hours), 3600 (1 hour) if a developer command has been
run or 300 (5 minutes) if HOMEBREW_NO_INSTALL_FROM_API is set.
HOMEBREW_BAT
: If set, use bat for the brew cat command.

: If set, use Bootsnap to speed up repeated brew calls. A no-op on Linux when
not using Homebrew's vendored, relocatable Ruby.
HOMEBREW_BOTTLE_DOMAIN
: Use this URL as the download mirror for bottles. If bottles at that URL are
temporarily unavailable, the default bottle domain will be used as a fallback
mirror. For example, HOMEBREW_BOTTLE_DOMAIN=http://localhost:8080 will cause
all bottles to download from the prefix http://localhost:8080/. If bottles
are not available at HOMEBREW_BOTTLE_DOMAIN they will be downloaded from the
default bottle domain.
Default: https://ghcr.io/v2/homebrew/core.
HOMEBREW_BREW_GIT_REMOTE
: Use this URL as the Homebrew/brew git(1) remote.
Default: https://github.com/Homebrew/brew.

HOMEBREW_CASK_OPTS
: Append these options to all cask commands. All --*dir options,
--language, --require-sha, --no-quarantine and --no-binaries are
supported. For example, you might add something like the following to your
~/.profile, ~/.bash_profile, or ~/.zshenv:
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_CLEANUP_PERIODIC_FULL_DAYS
: If set, brew install, brew upgrade and brew reinstall will cleanup all
formulae when this number of days has passed.
Default: 30.
HOMEBREW_COLOR
: If set, force colour output on non-TTY outputs.
HOMEBREW_CORE_GIT_REMOTE
: Use this URL as the Homebrew/homebrew-core git(1) remote.
Default: https://github.com/Homebrew/homebrew-core.
HOMEBREW_CURLRC
: If set to an absolute path (i.e. beginning with /), pass it with --config
when invoking curl(1). If set but not a valid path, do not pass
--disable, which disables the use of .curlrc.
HOMEBREW_CURL_PATH
: Linux only: Set this value to a new enough curl executable for Homebrew to
use.
Default: curl.
HOMEBREW_CURL_RETRIES
: Pass the given retry count to --retry when invoking curl(1).

: 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_DOCKER_REGISTRY_BASIC_AUTH_TOKEN
: Use this base64 encoded username and password for authenticating with a Docker
registry proxying GitHub Packages. If HOMEBREW_DOCKER_REGISTRY_TOKEN is set,
it will be used instead.
HOMEBREW_DOCKER_REGISTRY_TOKEN
: Use this bearer token for authenticating with a Docker registry proxying
GitHub Packages. Preferred over HOMEBREW_DOCKER_REGISTRY_BASIC_AUTH_TOKEN.
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_EVAL_ALL
: If set, brew commands evaluate all formulae and casks, executing their
arbitrary code, by default without requiring --eval-all. Required to cache
formula and cask descriptions.
HOMEBREW_FAIL_LOG_LINES

: If set, Homebrew will refuse to read formulae or casks provided from file
paths, e.g. brew install ./package.rb.
HOMEBREW_FORCE_BREWED_CA_CERTIFICATES
: If set, always use a Homebrew-installed ca-certificates rather than the
system version. Automatically set if the system version is too old.
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_BREWED_GIT
: If set, always use a Homebrew-installed git(1) rather than the system
version. Automatically set if the system version of git is too old.

GitHub will allow you a greater number of API requests. For more information,
see: https://docs.github.com/en/rest/overview/rate-limits-for-the-rest-api
Note: Homebrew doesn't require permissions for any of the scopes, but some developer commands may require additional permissions.
HOMEBREW_GITHUB_PACKAGES_TOKEN

HOMEBREW_NO_AUTOREMOVE
: If set, calls to brew cleanup and brew uninstall will not automatically
remove unused formula dependents.
HOMEBREW_NO_AUTO_UPDATE
: If set, do not automatically update before running some commands, e.g. brew install, brew upgrade and brew tap. Preferably, run this less often by
setting HOMEBREW_AUTO_UPDATE_SECS to a value higher than the default. Note
that setting this and e.g. tapping new taps may result in a broken
configuration. Please ensure you always run brew update before reporting any
issues.
HOMEBREW_NO_BOOTSNAP

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_INSTALLED_DEPENDENTS_CHECK
: If set, do not check for broken linkage of dependents or outdated dependents
after installing, upgrading or reinstalling formulae. This will result in
fewer dependents (and their dependencies) being upgraded or reinstalled but
may result in more breakage from running brew install formula or brew upgrade formula.
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 HOMEBREW_CLEANUP_PERIODIC_FULL_DAYS days. Alternatively,
HOMEBREW_NO_CLEANUP_FORMULAE allows specifying specific formulae to not
clean up.
HOMEBREW_NO_INSTALL_FROM_API
: If set, do not install formulae and casks in homebrew/core and homebrew/cask taps using Homebrew's API and instead use (large, slow) local checkouts of these repositories.

: If set, Homebrew not verify cryptographic attestations of build provenance for bottles from homebrew-core.
HOMEBREW_PIP_INDEX_URL
: If set, brew install formula will use this URL to download PyPI package
resources.
Default: https://pypi.org/simple.
HOMEBREW_PRY
: If set, use Pry for the brew irb command.
HOMEBREW_SIMULATE_MACOS_ON_LINUX
: If set, running Homebrew on Linux will simulate certain macOS code paths. This is useful when auditing macOS formulae while on Linux.
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. Set by default for
HOMEBREW_DEVELOPER or when running some developer commands.
HOMEBREW_SSH_CONFIG_PATH
: If set, Homebrew will use the given config file instead of ~/.ssh/config
when fetching Git repositories over SSH.
Default: $HOME/.ssh/config
HOMEBREW_SUDO_THROUGH_SUDO_USER
: If set, Homebrew will use the SUDO_USER environment variable to define the
user to sudo(8) through when running sudo(8).
HOMEBREW_SVN
: Use this as the svn(1) binary.
Default: A Homebrew-built Subversion (if installed), or the system-provided binary.
HOMEBREW_SYSTEM_ENV_TAKES_PRIORITY
: If set in Homebrew's system-wide environment file (/etc/homebrew/brew.env),
the system-wide environment file will be loaded last to override any prefix or
user settings.
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_UPGRADE_GREEDY
: If set, pass --greedy to all cask upgrade commands.
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.
HOMEBREW_VERIFY_ATTESTATIONS
: If set, Homebrew will use the gh tool to verify cryptographic attestations
of build provenance for bottles from homebrew-core.
SUDO_ASKPASS
: If set, pass the -A option when calling sudo(8).
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.
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
