bundle
[subcommand
]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.

, --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
or dump
Homebrew formula dependencies.
--cask
list
or dump
Homebrew cask dependencies.
--tap
list
or dump
Homebrew tap dependencies.
--mas
list
or dump
Mac App Store dependencies.
--whalebrew
list
or dump
Whalebrew dependencies.
--vscode
list
or dump
VSCode extensions.
--no-vscode
dump
without VSCode extensions. This is enabled by default if
HOMEBREW_BUNDLE_DUMP_NO_VSCODE
is set.
--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
.
command-not-found-init
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.

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/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. 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.env
if $XDG_CONFIG_HOME
is set or
$HOME/.homebrew/brew.env
otherwise (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=https://localhost:8080
will cause a formula
with the URL https://example.com/foo.tar.gz
to instead download from
https://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
https://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.
HOMEBREW_BAT_CONFIG_PATH
Use this as the bat
configuration file.
Default: $BAT_CONFIG_PATH
.
HOMEBREW_BAT_THEME
Use this as the bat
theme for syntax highlighting.
Default: $BAT_THEME
.
HOMEBREW_BOOTSNAP
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=https://localhost:8080
will cause
all bottles to download from the prefix https://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_BROWSER
Use this as the browser when opening project homepages.
Default: $BROWSER
or the OS’s default browser.

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.

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

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
