# brew(1) -- The Package Manager for Everywhere ## 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 without requiring `sudo`. ## TERMINOLOGY **formula** : Homebrew package definition that builds from upstream sources **cask** : Homebrew package definition that installs pre-compiled binaries built and signed by upstream **prefix** : path in which Homebrew is installed, e.g. `/opt/homebrew` or `/home/linuxbrew/.linuxbrew` **keg** : installation destination directory of a given **formula** version, e.g. `/opt/homebrew/Cellar/foo/0.1` **rack** : directory containing one or more versioned **kegs**, e.g. `/opt/homebrew/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. `/opt/homebrew/opt/foo` **Cellar** : directory containing one or more named **racks**, e.g. `/opt/homebrew/Cellar` **Caskroom** : directory containing one or more named **casks**, e.g. `/opt/homebrew/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 ## ESSENTIAL COMMANDS For the full command list, see the [COMMANDS](#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](#environment) section. ### `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](#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 ### `alias` \[`--edit`\] \[*`alias`*\|*`alias`*=*`command`*\] Show an alias's command. If no alias is given, print the whole list. `--edit` : Edit aliases in a text editor. Either one or all aliases may be opened at once. If the given alias doesn't exist it'll be pre-populated with a template. ### `as-console-user` *`command`* \[*`args`* ...\] Run a Homebrew command as the active macOS console user. This is intended for MDM, Munki and Jamf workflows where `brew` is invoked as root but Homebrew operations should run as the logged-in console user. The nested command is always dispatched through `HOMEBREW_BREW_FILE`. ### `autoremove` \[`--dry-run`\] Uninstall formulae that were only installed as a dependency of another formula and are now no longer needed. `-n`, `--dry-run` : List what would be uninstalled, but do not actually uninstall anything. ### `bundle` \[*`subcommand`*\] Bundler for non-Ruby dependencies from Homebrew formulae, Homebrew casks, Mac App Store dependencies, VSCode (and forks/variants) extensions, Go packages, Cargo packages, uv tools, Flatpak packages, WinGet packages, Krew plugins and npm packages. Note: Flatpak support is only available on Linux. `--file` : Read from or write to the `Brewfile` from this location. Use `--file=-` to pipe to stdin/stdout. `-g`, `--global` : Read from or write to the `Brewfile` from `$HOMEBREW_BUNDLE_FILE_GLOBAL` (if set), `${XDG_CONFIG_HOME}/homebrew/Brewfile` (if `$XDG_CONFIG_HOME` is set), `~/.homebrew/Brewfile` or `~/.Brewfile` otherwise. `brew bundle sh` \[`--check`\] \[`--no-secrets`\] : Run your shell in a `brew bundle exec` environment. `--install` : Run `install` before starting the shell. `--services` : Temporarily start services while running the shell. Enabled by default if `$HOMEBREW_BUNDLE_SERVICES` is set. `--check` : Check that all dependencies in the Brewfile are installed before starting the shell. Enabled by default if `$HOMEBREW_BUNDLE_CHECK` is set. `--no-secrets` : Attempt to remove secrets from the environment before starting the shell. `brew bundle remove` *`name`* \[...\] : Remove entries that match `name` from your `Brewfile`. Use `--formula`, `--cask`, `--tap`, `--mas`, `--vscode`, `--go`, `--cargo`, `--uv`, `--flatpak`, `--winget`, `--krew` and `--npm` to remove only entries of the corresponding type. Passing `--formula` also removes matches against formula aliases and old formula names. `--install` : Run `install` before removing entries. `--formula` : Remove Homebrew formula entries, including matches against formula aliases and old names. `--cask` : Remove Homebrew cask entries. `--tap` : Remove Homebrew tap entries. `--mas` : Remove entries for Mac App Store dependencies. `--vscode` : Remove entries for VSCode (and forks/variants) extensions. `--go` : Remove entries for Go packages. `--cargo` : Remove entries for Cargo packages. `--uv` : Remove entries for uv tools. `--flatpak` : Remove entries for Flatpak packages. Note: Linux only. `--winget` : Remove entries for WinGet packages. Note: WSL only. `--krew` : Remove entries for Krew plugins. `--npm` : Remove entries for npm packages. `brew bundle list` : List all dependencies present in the `Brewfile`. By default, only Homebrew formula dependencies are listed. `--install` : Run `install` before listing dependencies. `--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. `--vscode` : List VSCode (and forks/variants) extensions. `--go` : List Go packages. `--cargo` : List Cargo packages. `--uv` : List uv tools. `--flatpak` : List Flatpak packages. Note: Linux only. `--winget` : List WinGet packages. Note: WSL only. `--krew` : List Krew plugins. `--npm` : List npm packages. `brew bundle` \[`install`\|`upgrade`\] : Install and upgrade (by default) all dependencies from the `Brewfile`. Use this to restore a recorded installed state from a `Brewfile`. `brew bundle upgrade` is shorthand for `brew bundle install --upgrade`. 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_TAP_SKIP`. `-v`, `--verbose` : Print output from commands as they are run. `--no-upgrade` : Do not run `brew upgrade` on outdated dependencies.

Defaults to 1 (sequential). Use `auto` for the number of CPU cores (max 4). `-f`, `--force` : Run with `--force`/`--overwrite`. `--force-cleanup` : Perform cleanup after installing dependencies without asking. Enabled by default if `$HOMEBREW_BUNDLE_FORCE_INSTALL_CLEANUP` is set and `--global` is passed. `--zap` : Use `zap` instead of `uninstall` when cleaning up casks after installing dependencies. `brew bundle exec` \[`--check`\] \[`--no-secrets`\] \[`--sandbox=`*`path`*\] \[`--deny-network`\] *`command`* : Run an external command in an isolated build environment based on the `Brewfile` dependencies. This sanitised 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. `--install` : Run `install` before executing the command. `--services` : Temporarily start services while executing the command.

If you want to remove everything, use `--prune=all`. `-n`, `--dry-run` : Show what would be removed, but do not actually remove anything. `-s`, `--scrub` : Scrub the cache, including downloads for even the latest versions. Note that downloads for any installed formulae or casks will still not be deleted.

If you file a bug report, you will be required to provide this information. ### `deps` \[*`options`*\] \[*`formula`*\|*`cask`* ...\] Show dependencies for *`formula`*. When given multiple formula arguments, show the intersection of dependencies for each formula. By default, `deps` shows all required and recommended dependencies. If any version of each formula argument is installed and no other options are passed, this command displays their actual runtime dependencies (similar to `brew linkage`), which may differ from a formula's declared dependencies. *Note:* `--missing` and `--skip-recommended` have precedence over `--include-*`. `-n`, `--topological` : Sort dependencies in topological order. `-1`, `--direct` : Show only the direct dependencies declared in the formula. `--union` : Show the union of dependencies for multiple *`formula`*, instead of the intersection. `--full-name` : List dependencies by their full name. `--include-implicit` : Include implicit dependencies used to download and unpack source files. `--include-build` : Include `:build` dependencies for *`formula`*. `--include-optional` : Include `:optional` dependencies for *`formula`*. `--include-test` : Include `:test` dependencies for *`formula`* (non-recursive unless `--graph` or `--tree`). `--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. `--prune` : Prune parts of tree already seen. `--graph` : Show dependencies as a directed graph. `--dot` : Show text-based graph description in DOT format. `--annotate` : Mark any build, test, implicit, 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. `--brewfile` : Use formulae and casks listed in a Brewfile as inputs. Defaults to `./Brewfile`; use `--brewfile=`*`path`* to specify another. `--missing` : Show only missing dependencies. `--for-each` : Switch into the mode used when evaluating all formulae and casks, but only list dependencies for each provided *`formula`*, one formula per line. `--HEAD` : Show dependencies for HEAD version instead of stable version. `--os` : Show dependencies for the given operating system. `--arch` : Show dependencies for the given CPU architecture. `--formula` : Treat all named arguments as formulae. `--cask` : Treat all named arguments as casks. ### `desc` \[*`options`*\] *`formula`*\|*`cask`*\|*`text`*\|`/`*`regex`*`/` \[...\] Display *`formula`*'s name and one-line description. 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. `--formula` : Treat all named arguments as formulae. `--cask` : Treat all named arguments as casks. ### `developer` \[*`subcommand`*\] Control Homebrew's developer mode. When developer mode is enabled, `brew update` will update Homebrew to the latest commit on the `main` branch instead of the latest stable version along with some other behaviour changes. `brew developer` \[`state`\] : Display the current state of Homebrew's developer mode. `brew developer on` : Turn Homebrew's developer mode on. `brew developer off` : Turn Homebrew's developer mode off. ### `docs` Open Homebrew's online documentation at in a browser. ### `doctor`, `dr` \[`--list-checks`\] \[`--audit-debug`\] \[*`diagnostic_check`* ...\] 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. ### `exec`, `x` \[`--formulae=`*`formulae`*\] \[`--sandbox=`*`path`*\] \[`--deny-network`\] \[`--`\] *`command`* \[*`args`* ...\] Run *`command`* in an environment populated by Homebrew formulae. If `--formulae` is passed, Homebrew installs those comma-separated formulae if needed, prepends their executable directories and those of their dependencies to `PATH` and runs *`command`*. This allows *`command`* to be a script path such as `./script.sh`. If `--formulae` is omitted, Homebrew finds a formula that provides *`command`*, installs it if needed and runs that executable. Example: `brew exec --formulae=jq,yq -- ./script.sh` Scripts can also use a shebang on systems with `env -S`: `#!/usr/bin/env -S brew exec --formulae=jq,yq --` `--formulae` : Comma-separated formulae to install and add to `PATH` before running *`command`*. `--sandbox` : Run *`command`* in Homebrew's sandbox, allowing writes to *`path`* and Homebrew's temporary and cache directories. `--deny-network` : Deny network access from inside the sandbox. ### `fetch` \[*`options`*\] *`formula`*\|*`cask`* \[...\] Download a bottle (if available) or source packages for *`formula`*e and binaries for *`cask`*s. For files, also print SHA-256 checksums. `--os` : Download for the given operating system. (Pass `all` to download for all operating systems.) `--arch` : Download for the given CPU architecture. (Pass `all` to download for all architectures.) `--all-platforms` : Download for every supported operating system and architecture, plus each language for *`cask`*s, fetching each distinct URL once. `--bottle-tag` : Download a bottle for given tag. `--HEAD` : Fetch HEAD version instead of stable version. `-f`, `--force` : Remove a previously cached version and re-fetch. `-v`, `--verbose` : Do a verbose VCS checkout, if the URL represents a VCS. This is useful for seeing if an existing VCS cache has been updated. `--retry` : Retry if downloading fails or re-download if the checksum of a previously cached version no longer matches.

Enabled by default if `$HOMEBREW_UPGRADE_GREEDY` is set. `--greedy-latest` : Also include outdated casks including those with `version :latest`. `--greedy-auto-updates` : Also include outdated `auto_updates true` casks that would otherwise be skipped. ### `pin` \[`--formula`\] \[`--cask`\] *`installed_formula`*\|*`installed_cask`* \[...\] Pin the specified package, preventing it from being upgraded when issuing the `brew upgrade` *`formula`* or *`cask`* command. See also `unpin`. *Note:* Other packages which depend on newer versions of a pinned formula might not install or run correctly. Pinned casks with `auto_updates true` may update themselves outside Homebrew. `--formula` : Treat all named arguments as formulae. `--cask` : Treat all named arguments as casks. ### `postinstall`, `post_install` *`installed_formula`* \[...\] Rerun the post-install steps for *`formula`*. ### `pyenv-sync` Create symlinks for Homebrew's installed Python versions in `~/.pyenv/versions`.

Currently a no-op on non-Linux. ### `shellenv` \[*`shell`* ...\] 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 `$PATH`. Consider adding evaluation of this command's output to your dotfiles (e.g. `~/.bash_profile` or `~/.zprofile` on macOS and `~/.bashrc` or `~/.zshrc` on Linux) with e.g.: `eval "$(brew shellenv zsh)"` or `eval "$(brew shellenv bash)"` The shell should be specified explicitly with a supported shell name parameter but will be detected automatically if not provided (but this may not be correct). Unknown shells will output POSIX exports. ### `source` \[*`formula`* ...\] Open a *`formula`*'s source repository in a browser, or open Homebrew's own repository if no argument is provided. The repository URL is determined from the formula's head URL, stable URL, or homepage. Supports GitHub, GitLab, Bitbucket, Codeberg and SourceHut repositories. ### `tab` \[*`options`*\] *`installed_formula`*\|*`installed_cask`* \[...\] Edit tab information for installed formulae or casks.

To prevent removal, mark the formula as installed on request; to allow removal, mark the formula as not installed on request. `--installed-on-request` : Mark *`installed_formula`* or *`installed_cask`* as installed on request. `--no-installed-on-request` : Mark *`installed_formula`* or *`installed_cask`* as not installed on request. `--formula` : Only mark formulae. `--cask` : Only mark casks. ### `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. `--custom-remote` : Install or change a tap with a custom remote. Useful for mirrors. `--repair` : Add missing symlinks to tap manpages and shell completions.

See also `pin`. `--formula` : Treat all named arguments as formulae. `--cask` : Treat all named arguments as casks. ### `untap` \[`--force`\] *`tap`* \[...\] Remove a tapped formula repository. `-f`, `--force` : Uninstall all formulae and casks from this tap with `--force` before untapping. ### `untrust` \[*`options`*\] \[*`target`* ...\] Stop trusting non-official tap formulae, casks or commands. Trusted entries are stored in `${XDG_CONFIG_HOME}/homebrew/trust.json` if `$XDG_CONFIG_HOME` is set or `~/.homebrew/trust.json` otherwise. `--tap` : Untrust the named tap. `--formula` : Untrust the named formula. `--cask` : Untrust the named cask. `--command` : Untrust the named external command. ### `update`, `up` \[*`options`*\] Fetch the newest version of Homebrew and all formulae from GitHub using `git`(1) and perform any necessary migrations. `--auto-update` : Run on auto-updates (e.g. before `brew install`).

Omitting this flag searches the Homebrew primary repositories. `--team` : Specify the team to populate users from. The first part of the team name will be used as the organisation. `--quarter` : Homebrew contributions quarter to search (1-4). Omitting this flag searches the past year. If `--from` or `--to` are set, they take precedence. `--from` : Date (ISO 8601 format) to start searching contributions.

Completed-period GitHub searches are cached in Homebrew's cache and removed by normal cache pruning. `YEAR-1` is December of the previous year through February, `YEAR-2` is March through May, `YEAR-3` is June through August and `YEAR-4` is September through November. ### `create` \[*`options`*\] *`URL`* Generate a formula or, with `--cask`, a cask 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: `--autotools` : Create a basic template for an Autotools-style build. `--cabal` : Create a basic template for a Cabal build. `--cask` : Create a basic template for a cask. `--cmake` : Create a basic template for a CMake-style build. `--crystal` : Create a basic template for a Crystal build. `--go` : Create a basic template for a Go build. `--meson` : Create a basic template for a Meson-style build. `--node` : Create a basic template for a Node build. `--perl` : Create a basic template for a Perl build. `--python` : Create a basic template for a Python build. `--ruby` : Create a basic template for a Ruby build. `--rust` : Create a basic template for a Rust build. `--zig` : Create a basic template for a Zig build. `--no-fetch` : Homebrew will not download *`URL`* to the cache and will thus not add its SHA-256 to the formula for you, nor will it check the GitHub API for GitHub projects (to fill out its description and homepage). `--HEAD` : Indicate that *`URL`* points to the package's repository rather than a file. `--set-name` : Explicitly set the *`name`* of the new formula or cask. `--set-version` : Explicitly set the *`version`* of the new formula or cask. `--set-license` : Explicitly set the *`license`* of the new formula. `--tap` : Generate the new formula within the given tap, specified as *`user`*`/`*`repo`*. `-f`, `--force` : Ignore errors for disallowed formula names and names that shadow aliases. ### `debugger` \[`--open`\] *`command`* \[...\] Run the specified Homebrew command in debug mode.

Specifically, the command will create the new formula file at *`tap`*`/Formula/`*`formula`*`@`*`version`*`.rb`. If the tap is not installed yet, attempt to install/clone the tap before continuing. To extract a formula from a tap that is not `homebrew/core` use its fully-qualified form of *`user`*`/`*`repo`*`/`*`formula`*. `--git-revision` : Search for the specified *`version`* of *`formula`* starting at *`revision`* instead of HEAD. `--version` : Extract the specified *`version`* of *`formula`* instead of the most recent. `-f`, `--force` : Overwrite the destination formula if it already exists. ### `formula` *`formula`* \[...\] Display the path where *`formula`* is located. ### `generate-man-completions` \[`--no-exit-code`\] Generate Homebrew's manpages and shell completions. `--no-exit-code` : Exit with code 0 even if no changes were made. ### `generate-zap` \[`--name`\] *`cask_or_name`* Generate a `zap` stanza for a cask by scanning the system for associated files and directories. Accepts a cask token (e.g. `firefox`) or, with `--name`, a raw application name string (e.g. `Firefox`). When a cask token is given, the application name is resolved from the cask's `app` artifact. The target application should have been launched at least once so that preference files and caches exist on disk. Outputs `trash`, `delete`, and `rmdir` directives suitable for pasting into a cask definition. `--name` : Treat the argument as a raw application name instead of a cask token. ### `install-bundler-gems` \[`--groups=`\] \[`--add-groups=`\] Install Homebrew's Bundler gems. `--groups` : Installs the specified comma-separated list of gem groups (default: last used).

For example, `brew ruby -e "puts :gcc.f.deps"` or `brew ruby script.rb`. Run e.g. `brew ruby -- --version` to pass arbitrary arguments to `ruby`. `-r` : Load a library using `require`. `-e` : Execute the given text string as a script. ### `rubydoc` \[`--only-public`\] \[`--open`\] Generate Homebrew's RubyDoc documentation. `--only-public` : Only generate public API documentation. `--open` : Open generated documentation in a browser. ### `sh` \[*`options`*\] \[*`file`*\] Enter an interactive shell for Homebrew's build environment. Use years-battle-hardened build logic to help your `./configure && make && make install` and even your `gem install` succeed. Especially handy if you run Homebrew in an Xcode-only configuration since it adds tools like `make` to your `$PATH` which build systems would not find otherwise. With `--ruby`, enter an interactive shell for Homebrew's Ruby environment. This sets up the correct Ruby paths, `$GEM_HOME` and bundle configuration used by Homebrew's development tools. The environment includes gems from the installed groups, making tools like RuboCop, Sorbet and RSpec available via `bundle exec`. `-r`, `--ruby` : Set up Homebrew's Ruby environment. `--env` : Use the standard `$PATH` instead of superenv's when `std` is passed. `-c`, `--cmd` : Execute commands in a non-interactive shell. ### `style` \[*`options`*\] \[*`file`*\|*`tap`*\|*`formula`*\|*`cask`* ...\] Check formulae or files for conformance to Homebrew style guidelines. Lists of *`file`*, *`tap`* and *`formula`* may not be combined. If none are provided, `style` will run style checks on the whole Homebrew library, including core code and all formulae. `--fix` : Fix style violations automatically using RuboCop's auto-correct feature. `--todo` : Add `rubocop:todo` comments for RuboCop violations that remain after auto-correction. Requires `--fix`. `--reset-cache` : Reset the RuboCop cache. `--changed` : Check files that were changed from the `main` branch. `--formula` : Treat all named arguments as formulae. `--cask` : Treat all named arguments as casks. `--only-cops` : Specify a comma-separated *`cops`* list to check for violations of only the listed RuboCop cops. `--except-cops` : Specify a comma-separated *`cops`* list to skip checking for violations of the listed RuboCop cops. ### `tap-new` \[*`options`*\] *`user`*`/`*`repo`* Generate the template files for a new tap. `--no-git` : Don't initialise a Git repository for the tap. `--branch` : Initialise a Git repository and set up GitHub Actions workflows with the specified branch name (default: `main`). `--github-packages` : Upload bottles to GitHub Packages. ### `test` \[*`options`*\] *`installed_formula`* \[...\] Run the test method provided by an installed formula. There is no standard output or return code, but generally it should notify the user if something is wrong with the installed formula. *Example:* `brew install jruby && brew test jruby` `-f`, `--force` : Test formulae even if they are unlinked. `--HEAD` : Test the HEAD version of a formula. `--keep-tmp` : Retain the temporary files created for the test. `--retry` : Retry if a testing fails. ### `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. `--build-from-source` : Build from source rather than building bottles. `--build-dependents-from-source` : Build dependents from source rather than testing bottles. `--junit` : generate a JUnit XML test results file. `--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. `--only-json-tab` : Run `brew bottle --only-json-tab` to build new bottles that do not contain a tab. `--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.

This optional post-upload test checks that all the bottles were uploaded correctly. It is not run unless requested and only needs to be run on a single machine. The bottle commit to be tested must be on the tested branch. `--only-cleanup-after` : Only run the post-cleanup step. Needs `--cleanup`, except in GitHub Actions. `--testing-formulae` : Use these testing formulae rather than running the formulae detection steps. `--added-formulae` : Use these added formulae rather than running the formulae detection steps. `--deleted-formulae` : Use these deleted formulae rather than running the formulae detection steps. `--skipped-or-failed-formulae` : Use these skipped or failed formulae from formulae steps for a formulae dependents step. `--tested-formulae` : Use these tested formulae from formulae steps for a formulae dependents step. ### `tests` \[*`options`*\] Run Homebrew's unit and integration tests. `--coverage` : Generate code coverage reports. `--generic` : Run only OS-agnostic tests. `--online` : Include tests that use the GitHub API and tests that use any of the taps for official external commands. `--debug` : Enable debugging using `ruby/debug`, or surface the standard `odebug` output. `--changed` : Only runs tests on files that were changed from the `main` branch. `--fail-fast` : Exit early on the first failing test. `--no-parallel` : Run tests serially. `--stackprof` : Use `stackprof` to profile tests. `--vernier` : Use `vernier` to profile tests. `--ruby-prof` : Use `ruby-prof` to profile tests. `--only` : Run only `_spec.rb`.

When run without `--no-parallel` this will output the slowest tests for each parallel test process. `--seed` : Randomise tests with the specified *`value`* instead of a random seed. ### `typecheck`, `tc` \[*`options`*\] \[*`tap`* ...\] Check for typechecking errors using Sorbet. `--fix` : Automatically fix type errors. `-q`, `--quiet` : Silence all non-critical errors. `--update` : Update RBI files. `--update-all` : Update all RBI files rather than just updated gems. `--suggest-typed` : Try upgrading `typed` sigils. `--lsp` : Start the Sorbet LSP server. `--dir` : Typecheck all files in a specific directory. `--file` : Typecheck a single file. `--ignore` : Ignores input files that contain the given string in their paths (relative to the input path passed to Sorbet). ### `unbottled` \[*`options`*\] \[*`formula`* ...\] Show the unbottled dependents of formulae. `--tag` : Use the specified bottle tag (e.g. `big_sur`) instead of the current OS. `--dependents` : Skip getting analytics data and sort by number of dependents instead. `--total` : Print the number of unbottled and total formulae. `--lost` : Print the `homebrew/core` commits where bottles were lost in the last week. ### `unpack` \[*`options`*\] *`formula`*\|*`cask`* \[...\] Unpack the files for the *`formula`* or *`cask`* into subdirectories of the current working directory. `--destdir` : Create subdirectories in the directory named by *`path`* instead. `--patch` : Patches for *`formula`* will be applied to the unpacked source. `-g`, `--git` : Initialise a Git repository in the unpacked source. This is useful for creating patches for the software. `-f`, `--force` : Overwrite the destination directory if it already exists. `--formula` : Treat all named arguments as formulae. `--cask` : Treat all named arguments as casks. ### `update-perl-resources` \[`--print-only`\] \[`--ignore-errors`\] *`formula`* \[...\] Update versions for CPAN resource blocks in *`formula`*. `-p`, `--print-only` : Print the updated resource blocks instead of changing *`formula`*. `--ignore-errors` : Continue processing even if some resources can't be resolved. ### `update-python-resources` \[*`options`*\] *`formula`* \[...\] Update versions for PyPI resource blocks in *`formula`*. `-p`, `--print-only` : Print the updated resource blocks instead of changing *`formula`*. `--ignore-errors` : Record all discovered resources, even those that can't be resolved successfully. This option is ignored for homebrew/core formulae. `--ignore-non-pypi-packages` : Don't fail if *`formula`* is not a PyPI package. `--ignore-main-package-cooldown` : Bypass the release cooldown for *`formula`*'s own package when resolving resources. Its dependencies still respect the cooldown. This option is ignored for official taps. `--install-dependencies` : Install missing dependencies required to update resources. `--version` : Use the specified *`version`* when finding resources for *`formula`*. If no version is specified, the current version for *`formula`* will be used. `--package-name` : Use the specified *`package-name`* when finding resources for *`formula`*. If no package name is specified, it will be inferred from the formula's stable URL. `--extra-packages` : Include these additional packages when finding resources. `--exclude-packages` : Exclude these packages when finding resources. ### `update-test` \[*`options`*\] Run a test of `brew update` with a new repository clone.

This is done by first fetching the given bottles and then verifying their provenance. Note that this command depends on the GitHub CLI. Run `brew install gh`. `--os` : Download for the given operating system. (Pass `all` to download for all operating systems.) `--arch` : Download for the given CPU architecture. (Pass `all` to download for all architectures.) `--bottle-tag` : Download a bottle for given tag. `--deps` : Also download dependencies for any listed *`formula`*. `-f`, `--force` : Remove a previously cached version and re-fetch. `-j`, `--json` : Return JSON for the attestation data for each bottle. ### `which-update` \[*`options`*\] *`database`* Database update for `brew which-formula`. `--bottle-json-dir` : Use generated bottle JSON files in the given directory to update formula entries. `--removed-formulae-file` : Remove database entries for formulae listed in the given file. `--pull-request` : Update entries for formula changes in the given pull request number. `--repository` : GitHub repository for `--pull-request` (default: `$GITHUB_REPOSITORY`). `--summary-file` : Output a summary of the changes to a file. ## GLOBAL CASK OPTIONS These options are applicable to the `install`, `reinstall` and `upgrade` subcommands with the `--cask` switch. `--appdir` : Target location for Applications (default: `/Applications`). `--appimagedir` : Target location for AppImages (default: `~/Applications`). `--keyboard-layoutdir` : Target location for Keyboard Layouts (default: `/Library/Keyboard Layouts`). `--colorpickerdir` : Target location for Color Pickers (default: `~/Library/ColorPickers`). `--prefpanedir` : Target location for Preference Panes (default: `~/Library/PreferencePanes`). `--qlplugindir` : Target location for Quick Look Plugins (default: `~/Library/QuickLook`). `--mdimporterdir` : Target location for Spotlight Plugins (default: `~/Library/Spotlight`). `--dictionarydir` : Target location for Dictionaries (default: `~/Library/Dictionaries`). `--fontdir` : Target location for Fonts (default: `~/Library/Fonts`). `--servicedir` : Target location for Services (default: `~/Library/Services`). `--input-methoddir` : Target location for Input Methods (default: `~/Library/Input Methods`). `--internet-plugindir` : Target location for Internet Plugins (default: `~/Library/Internet Plug-Ins`). `--audio-unit-plugindir` : Target location for Audio Unit Plugins (default: `~/Library/Audio/Plug-Ins/Components`). `--vst-plugindir` : Target location for VST Plugins (default: `~/Library/Audio/Plug-Ins/VST`). `--vst3-plugindir` : Target location for VST3 Plugins (default: `~/Library/Audio/Plug-Ins/VST3`). `--screen-saverdir` : Target location for Screen Savers (default: `~/Library/Screen Savers`). `--language` : Comma-separated list of language codes to prefer for cask installation. The first matching language is used, otherwise it reverts to the cask's default language. The default value is the language of your system. ## GLOBAL OPTIONS These options are applicable across multiple subcommands. `-d`, `--debug` : Display any debugging information. `-q`, `--quiet` : Make some output more quiet. `-v`, `--verbose` : Make some output more verbose. `-h`, `--help` : Show this message. ## 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: ## 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`. ## SPECIFYING CASKS Many commands that work with casks 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_*` 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 `$XDG_CONFIG_HOME` is set or `~/.homebrew/brew.env` otherwise (user-specific) User-specific environment files take precedence over prefix-specific files and prefix-specific files take precedence over system-wide files (unless `$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. Each entry is a `user/repository` name (which matches only taps using the default GitHub remote) or a remote URL (required to match taps with a custom remote). `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, `export 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` : When `$HOMEBREW_ARTIFACT_DOMAIN` and `$HOMEBREW_ARTIFACT_DOMAIN_NO_FALLBACK` are both set, if the request to `$HOMEBREW_ARTIFACT_DOMAIN` fails then Homebrew will error rather than trying any other/default URLs. `HOMEBREW_AUTO_UPDATE_SECS` : Run `brew update` once every `$HOMEBREW_AUTO_UPDATE_SECS` seconds before some commands, e.g. `brew install`, `brew upgrade` or `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_AVOID_NESTED_SANDBOXING` : If set, skip Homebrew's sandbox when it is itself running inside another sandbox, for an unprivileged user outside the default prefix. This trades Homebrew's build-time network and filesystem denial for trust in the outer sandbox. Homebrew errors out if the prefix or group makes skipping unsupported. `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_BOTTLE_DOMAIN` : Use this URL as the download mirror for bottles and their manifests. If a bottle or manifest is unavailable at the mirror, the default bottle domain will be used as a fallback. Prefer `$HOMEBREW_ARTIFACT_DOMAIN` for a mirror that transparently proxies all Homebrew downloads. For example, `export HOMEBREW_BOTTLE_DOMAIN=http://localhost:8080` will cause all bottles to download from the prefix `http://localhost:8080/`. *Default:* `https://ghcr.io/v2/homebrew/core`. `HOMEBREW_BREW_GIT_REMOTE` : Use this URL as the Homebrew/brew `git`(1) remote. *Default:* `https://github.com/Homebrew/brew`. `HOMEBREW_BROWSER` : Use this as the browser when opening project homepages. *Default:* `$BROWSER` or the OS's default browser. `HOMEBREW_BUNDLE_CLEANUP_NO_BREW` : If set, `brew bundle cleanup` will not clean up formula dependencies. `HOMEBREW_BUNDLE_CLEANUP_NO_CARGO` : If set, `brew bundle cleanup` will not clean up Cargo packages. `HOMEBREW_BUNDLE_CLEANUP_NO_CASK` : If set, `brew bundle cleanup` will not clean up cask dependencies. `HOMEBREW_BUNDLE_CLEANUP_NO_FLATPAK` : If set, `brew bundle cleanup` will not clean up Flatpak packages. `HOMEBREW_BUNDLE_CLEANUP_NO_GO` : If set, `brew bundle cleanup` will not clean up Go packages. `HOMEBREW_BUNDLE_CLEANUP_NO_KREW` : If set, `brew bundle cleanup` will not clean up Krew plugins. `HOMEBREW_BUNDLE_CLEANUP_NO_MAS` : If set, `brew bundle cleanup` will not clean up Mac App Store dependencies. `HOMEBREW_BUNDLE_CLEANUP_NO_NPM` : If set, `brew bundle cleanup` will not clean up npm packages. `HOMEBREW_BUNDLE_CLEANUP_NO_TAP` : If set, `brew bundle cleanup` will not clean up tap dependencies. `HOMEBREW_BUNDLE_CLEANUP_NO_UV` : If set, `brew bundle cleanup` will not clean up uv tools. `HOMEBREW_BUNDLE_CLEANUP_NO_VSCODE` : If set, `brew bundle cleanup` will not clean up VSCode (and forks/variants) extensions. `HOMEBREW_BUNDLE_CLEANUP_NO_WINGET` : If set, `brew bundle cleanup` will not clean up WinGet packages. `HOMEBREW_BUNDLE_DUMP_NO_BREW` : If set, `brew bundle dump` will not dump formula dependencies. `HOMEBREW_BUNDLE_DUMP_NO_CARGO` : If set, `brew bundle dump` will not dump Cargo packages. `HOMEBREW_BUNDLE_DUMP_NO_CASK` : If set, `brew bundle dump` will not dump cask dependencies. `HOMEBREW_BUNDLE_DUMP_NO_FLATPAK` : If set, `brew bundle dump` will not dump Flatpak packages. `HOMEBREW_BUNDLE_DUMP_NO_GO` : If set, `brew bundle dump` will not dump Go packages. `HOMEBREW_BUNDLE_DUMP_NO_KREW` : If set, `brew bundle dump` will not dump Krew plugins. `HOMEBREW_BUNDLE_DUMP_NO_MAS` : If set, `brew bundle dump` will not dump Mac App Store dependencies. `HOMEBREW_BUNDLE_DUMP_NO_NPM` : If set, `brew bundle dump` will not dump npm packages. `HOMEBREW_BUNDLE_DUMP_NO_TAP` : If set, `brew bundle dump` will not dump tap dependencies. `HOMEBREW_BUNDLE_DUMP_NO_UV` : If set, `brew bundle dump` will not dump uv tools. `HOMEBREW_BUNDLE_DUMP_NO_VSCODE` : If set, `brew bundle dump` will not dump VSCode (and forks/variants) extensions. `HOMEBREW_BUNDLE_DUMP_NO_WINGET` : If set, `brew bundle dump` will not dump WinGet packages. `HOMEBREW_BUNDLE_FORCE_INSTALL_CLEANUP` : If set, run `brew bundle cleanup --force` after `brew bundle install`. `HOMEBREW_BUNDLE_JOBS` : Use this value as the number of formula installations to run in parallel for `brew bundle install`. Use `auto` for the number of CPU cores (max 4). *Default:* `auto`. `HOMEBREW_BUNDLE_NO_DESCRIBE` : If set, do not enable bundle description comments from `$HOMEBREW_BUNDLE_DESCRIBE` or the default. This does not disable an explicit `--describe`. `HOMEBREW_BUNDLE_NO_JOBS` : If set, do not enable parallel jobs from `$HOMEBREW_BUNDLE_JOBS` or its default. This does not disable an explicit `--jobs`. `HOMEBREW_BUNDLE_SECRETS` : If set, do not enable the default secret scrubbing. This does not disable an explicit `--no-secrets`. `HOMEBREW_BUNDLE_USER_CACHE` : If set, use this directory as the `bundle`(1) user cache. `HOMEBREW_CACHE` : Use this directory as the download cache. *Default:* macOS: `~/Library/Caches/Homebrew`, Linux: `$XDG_CACHE_HOME/Homebrew` or `~/.cache/Homebrew`. `HOMEBREW_CASK_OPTS` : Append these options to all `cask` commands. All `--*dir` options, `--language`, `--require-sha` and `--no-binaries` are supported. For example, you might add something like the following to your `~/.profile`, `~/.bash_profile`, or `~/.zshenv`: `export HOMEBREW_CASK_OPTS="--appdir=${HOME}/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). *Default:* `3`. `HOMEBREW_CURL_VERBOSE` : If set, pass `--verbose` when invoking `curl`(1). `HOMEBREW_DEBUG` : If set, always assume `--debug` when running commands. `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_DEBREW` : If set, the interactive formula debugger available via `--debug` will be disabled. `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:* `$DISPLAY`. `HOMEBREW_DISPLAY_INSTALL_TIMES` : If set, print install times for each formula at the end of the run. `HOMEBREW_DOCKER_REGISTRY_BASIC_AUTH_TOKEN` : Use this base64 encoded username and password for authenticating with a Docker registry proxying GitHub Packages. If set to `none`, no authentication header will be sent. This can be used, if remote `$HOMEBREW_ARTIFACT_DOMAIN` does not support any authentication. 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_DOWNLOAD_CONCURRENCY` : Homebrew will download in parallel using this many concurrent connections. The default, `auto`, will use twice the number of available CPU cores (what our benchmarks showed to produce the best performance). If set to `1`, Homebrew will download in serial. *Default:* `auto`. `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_ENV_SYNC_STRICT` : If set, `brew *env-sync` will only sync the exact installed versions of formulae. `HOMEBREW_FAIL_LOG_LINES` : Output this many lines of output on formula `system` failures. *Default:* `15`. `HOMEBREW_FORBIDDEN_CASKS` : A space-separated list of casks.

You can create one at . If set, GitHub will allow you a greater number of API requests. For more information, see: *Note:* Homebrew doesn't require permissions for any of the scopes, but some developer commands may require additional permissions. `HOMEBREW_GITHUB_PACKAGES_TOKEN` : Use this GitHub personal access token when accessing the GitHub Packages Registry (where bottles may be stored). `HOMEBREW_GITHUB_PACKAGES_USER` : Use this username when accessing the GitHub Packages Registry (where bottles may be stored). `HOMEBREW_GIT_COMMITTER_EMAIL` : Set the Git committer email to this value. `HOMEBREW_GIT_COMMITTER_NAME` : Set the Git committer name to this value. `HOMEBREW_GIT_EMAIL` : Set the Git author name and, if `$HOMEBREW_GIT_COMMITTER_EMAIL` is unset, committer email to this value. `HOMEBREW_GIT_NAME` : Set the Git author name and, if `$HOMEBREW_GIT_COMMITTER_NAME` is unset, committer name to this value. `HOMEBREW_GIT_PATH` : Linux only: Set this value to a new enough `git` executable for Homebrew to use. *Default:* `git`. `HOMEBREW_INSTALL_BADGE` : Print this text before the installation summary of each successful build. *Default:* The "Beer Mug" emoji. `HOMEBREW_LIVECHECK_AUTOBUMP` : If set, `brew livecheck` will include data for packages that are autobumped by BrewTestBot. `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:* `${XDG_CONFIG_HOME}/homebrew/livecheck_watchlist.txt` if `$XDG_CONFIG_HOME` is set or `~/.homebrew/livecheck_watchlist.txt` otherwise. `HOMEBREW_LOCK_CONTEXT` : If set, Homebrew will add this output as additional context for locking errors. This is useful when running `brew` in the background. `HOMEBREW_LOGS` : Use this directory to store log files. *Default:* macOS: `~/Library/Logs/Homebrew`, Linux: `${XDG_CACHE_HOME}/Homebrew/Logs` or `~/.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.

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` : If set, do not use Bootsnap to speed up repeated `brew` calls. `HOMEBREW_NO_CLEANUP_FORMULAE` : A comma-separated list of 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. `HOMEBREW_NO_INSTALL_UPGRADE` : If set, `brew install` *`formula|cask`* will not upgrade *`formula|cask`* if it is installed but outdated. `HOMEBREW_NO_PATH_SHADOW_CHECK` : If set, `brew info` and `brew install` will not warn when a formula's executables are shadowed by other commands earlier on `$PATH`. `HOMEBREW_NO_REQUIRE_TAP_TRUST` : If set, do not require non-official tap formulae, casks or commands to be trusted. This is not recommended and will be removed in a later release. Also enables commands that evaluate all formulae and casks. `HOMEBREW_NO_SANDBOX_LINUX` : If set, disable the Linux sandbox. `HOMEBREW_NO_UPDATE_REPORT_NEW` : If set, `brew update` will not show the list of newly added formulae/casks. `HOMEBREW_NO_UPGRADE_AUTO_UPDATES_CASKS` : If set, `brew upgrade` will not automatically upgrade casks with `auto_updates true`. Does not affect `--greedy` or `--greedy-auto-updates` upgrades. `HOMEBREW_NO_UPGRADE_QUIT_CASKS` : If set, `brew upgrade` will not quit running applications for casks during upgrades. `HOMEBREW_NO_VERIFY_ATTESTATIONS` : If set, Homebrew will not verify cryptographic attestations of build provenance for bottles from homebrew-core. `HOMEBREW_PIP_INDEX_URL` : If set, `brew install` *`formula`* will use this URL to download PyPI package resources. *Default:* `https://pypi.org/simple`. `HOMEBREW_PRY` : If set, use Pry for the `brew irb` command. `HOMEBREW_REQUIRE_TAP_TRUST` : If set, require non-official tap formulae, casks and commands to be trusted with `brew trust` before Homebrew loads them. This is the default unless `$HOMEBREW_NO_REQUIRE_TAP_TRUST` is set. Also enables commands that evaluate all formulae and casks. *Default:* `true`. `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 `$HOMEBREW_DEVELOPER`, do not use bottles from older versions of macOS. This is useful in development on new macOS versions. `HOMEBREW_SORBET_RECURSIVE` : If set along with `$HOMEBREW_SORBET_RUNTIME`, enable recursive typechecking using Sorbet. Automatically enabled when running `brew tests`. `HOMEBREW_SORBET_RUNTIME` : If set, enable runtime typechecking using Sorbet. Set by default when running `brew test`, `brew test-bot` or `brew tests`. `HOMEBREW_SSH_CONFIG_PATH` : If set, Homebrew will use the given config file instead of `~/.ssh/config` when fetching Git repositories over SSH. *Default:* `~/.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: `/var/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_UPGRADE_GREEDY_CASKS` : A space-separated list of casks. Homebrew will act as if `--greedy` was passed when upgrading any cask on this list. `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. ## 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 ## SEE ALSO Homebrew Documentation: Homebrew API: `git`(1), `git-log`(1) ## AUTHORS Homebrew's Project Leader is Mike McQuaid.
