.TP
\fBconfig\fR
Show Homebrew and system configuration useful for debugging\. If you file a bug report, you will likely be asked for this information if you do not provide it\.
\fBdeps\fR [\fB\-\-1\fR] [\fB\-n\fR] [\fB\-\-union\fR] [\fB\-\-full\-name\fR] [\fB\-\-installed\fR] [\fB\-\-include\-build\fR] [\fB\-\-include\-optional\fR] [\fB\-\-skip\-recommended\fR] \fIformulae\fR
Show dependencies for \fIformulae\fR\. When given multiple formula arguments, show the intersection of dependencies for \fIformulae\fR\.
If \fB\-\-1\fR is passed, only show dependencies one level down, instead of recursing\.
If \fB\-n\fR is passed, show dependencies in topological order\.
.
.IP
If \fB\-\-union\fR is passed, show the union of dependencies for \fIformulae\fR, instead of the intersection\.
.
.IP
If \fB\-\-full\-name\fR is passed, list dependencies by their full name\.
.
.IP
If \fB\-\-installed\fR is passed, only list those dependencies that are currently installed\.
By default, \fBdeps\fR shows required and recommended dependencies for \fIformulae\fR\. To include the \fB:build\fR type dependencies, pass \fB\-\-include\-build\fR\. Similarly, pass \fB\-\-include\-optional\fR to include \fB:optional\fR dependencies\. To skip \fB:recommended\fR type dependencies, pass \fB\-\-skip\-recommended\fR\.
.
.TP
\fBdeps\fR \fB\-\-tree\fR [\fIfilters\fR] (\fIformulae\fR|\fB\-\-installed\fR)
Show dependencies as a tree\. When given multiple formula arguments, output individual trees for every formula\.
If \fB\-\-installed\fR is passed, output a tree for every installed formula\.

Search both name and description (\fB\-s\fR), just the names (\fB\-n\fR), or just the descriptions (\fB\-d\fR) for \fB<pattern>\fR\. \fB<pattern>\fR is by default interpreted as a literal string; if flanked by slashes, it is instead interpreted as a regular expression\. Formula descriptions are cached; the cache is created on the first search, making that search slower than subsequent ones\.
.TP
\fBdiy\fR [\fB\-\-name=\fR\fIname\fR] [\fB\-\-version=\fR\fIversion\fR]
Automatically determine the installation prefix for non\-Homebrew software\.
.
.IP

\fIformula\fR is usually the name of the formula to install, but it can be specified in several different ways\. See \fISPECIFYING FORMULAE\fR\.
If \fB\-\-debug\fR is passed and brewing fails, open an interactive debugging session with access to IRB or a shell inside the temporary build directory\.
.
.IP
If \fB\-\-env=std\fR is passed, use the standard build environment instead of superenv\.
.
.IP
If \fB\-\-env=super\fR is passed, use superenv even if the formula specifies the standard build environment\.
.IP
If \fB\-\-ignore\-dependencies\fR is passed, skip installing any dependencies of any kind\. If they are not already present, the formula will probably fail to install\.
If \fB\-\-only\-dependencies\fR is passed, install the dependencies with specified options but do not install the specified formula\.
.
.IP
If \fB\-\-cc=\fR\fIcompiler\fR is passed, attempt to compile using \fIcompiler\fR\. \fIcompiler\fR should be the name of the compiler\'s executable, for instance \fBgcc\-4\.2\fR for Apple\'s GCC 4\.2, or \fBgcc\-4\.9\fR for a Homebrew\-provided GCC 4\.9\.
If \fB\-\-build\-from\-source\fR or \fB\-s\fR is passed, compile the specified \fIformula\fR from source even if a bottle is provided\. Dependencies will still be installed from bottles if they are available\.
.
.IP
If \fBHOMEBREW_BUILD_FROM_SOURCE\fR is set, regardless of whether \fB\-\-build\-from\-source\fR was passed, then both \fIformula\fR and the dependencies installed as part of this process are built from source even if bottles are available\.
If \fB\-\-force\-bottle\fR is passed, 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\.
.
.IP
If \fB\-\-devel\fR is passed, and \fIformula\fR defines it, install the development version\.
.
.IP
If \fB\-\-HEAD\fR is passed, and \fIformula\fR defines it, install the HEAD version, aka master, trunk, unstable\.
If \fB\-\-keep\-tmp\fR is passed, the temporary files created during installation are not deleted\.
\fBinstall\fR \fB\-\-interactive\fR [\fB\-\-git\fR] \fIformula\fR
Download and patch \fIformula\fR, then open a shell\. This allows the user to run \fB\./configure \-\-help\fR and otherwise determine how to turn the software package into a Homebrew formula\.
If \fB\-\-git\fR is passed, Homebrew will create a Git repository, useful for creating patches to the software\.
.TP
\fBirb\fR [\fB\-\-examples\fR]
Enter the interactive Homebrew Ruby shell\.
If \fB\-\-examples\fR is passed, several examples will be shown\.
.TP
\fBleaves\fR

.TP
\fBln\fR, \fBlink\fR [\fB\-\-overwrite\fR] [\fB\-\-dry\-run\fR] [\fB\-\-force\fR] \fIformula\fR
Symlink all of \fIformula\fR\'s installed files into the Homebrew prefix\. This is done automatically when you install formulae but can be useful for DIY installations\.
If \fB\-\-overwrite\fR is passed, Homebrew will delete files which already exist in the prefix while linking\.
If \fB\-\-dry\-run\fR or \fB\-n\fR is passed, Homebrew will list all files which would be linked or which would be deleted by \fBbrew link \-\-overwrite\fR, but will not actually link or delete any files\.
.IP
If \fB\-\-force\fR is passed, Homebrew will allow keg\-only formulae to be linked\.
.
.TP
\fBlinkapps\fR [\fB\-\-local\fR] [\fIformulae\fR]
Find installed formulae that provide \fB\.app\fR\-style macOS apps and symlink them into \fB/Applications\fR, allowing for easier access (deprecated)\.
.
.IP
Unfortunately \fBbrew linkapps\fR cannot behave nicely with e\.g\. Spotlight using either aliases or symlinks and Homebrew formulae do not build "proper" \fB\.app\fR bundles that can be relocated\. Instead, please consider using \fBbrew cask\fR and migrate formulae using \fB\.app\fRs to casks\.
If no \fIformulae\fR are provided, all of them will have their apps symlinked\.
If provided, \fB\-\-local\fR will symlink them into the user\'s \fB~/Applications\fR directory instead of the system directory\.
List all installed formulae\. If \fB\-\-full\-name\fR is passed, print formulae with fully\-qualified names\. If \fB\-\-full\-name\fR is not passed, any other options (e\.g\. \fB\-t\fR) are passed to \fBls\fR which produces the actual output\.
List all files in the Homebrew prefix not installed by Homebrew\.
\fBlist\fR, \fBls\fR [\fB\-\-versions\fR [\fB\-\-multiple\fR]] [\fB\-\-pinned\fR] [\fIformulae\fR]

\fBmigrate\fR [\fB\-\-force\fR] \fIformulae\fR
Migrate renamed packages to new name, where \fIformulae\fR are old names of packages\.
If \fB\-\-force\fR is passed, then treat installed \fIformulae\fR and passed \fIformulae\fR like if they are from same taps and migrate them anyway\.
\fBmissing\fR [\fB\-\-hide=\fR\fIhidden\fR] [\fIformulae\fR]
Check the given \fIformulae\fR for missing dependencies\. If no \fIformulae\fR are given, check all installed brews\.
If \fB\-\-hide=\fR\fIhidden\fR is passed, act as if none of \fIhidden\fR are installed\. \fIhidden\fR should be a comma\-separated list of formulae\.

Rerun the post\-install steps for \fIformula\fR\.
.
.TP
\fBprune\fR [\fB\-\-dry\-run\fR]
Remove dead symlinks from the Homebrew prefix\. This is generally not needed, but can be useful when doing DIY installations\. Also remove broken app symlinks from \fB/Applications\fR and \fB~/Applications\fR that were previously created by \fBbrew linkapps\fR\.
.IP
If \fB\-\-dry\-run\fR or \fB\-n\fR is passed, show what would be removed, but do not actually remove anything\.
.
.TP
\fBreinstall\fR \fIformula\fR
Uninstall and then install \fIformula\fR\.
\fBsearch\fR, \fB\-S\fR
Display all locally available formulae for brewing (including tapped ones)\. No online search is performed if called without arguments\.
\fBsearch\fR [\fB\-\-desc\fR] \fItext\fR|\fB/\fR\fItext\fR\fB/\fR
Perform a substring search of formula names for \fItext\fR\. If \fItext\fR is surrounded with slashes, then it is interpreted as a regular expression\. The search for \fItext\fR is extended online to some popular taps\.
.IP
If \fB\-\-desc\fR is passed, browse available packages matching \fItext\fR including a description for each\.
.
\fBsearch\fR (\fB\-\-debian\fR|\fB\-\-fedora\fR|\fB\-\-fink\fR|\fB\-\-macports\fR|\fB\-\-opensuse\fR|\fB\-\-ubuntu\fR) \fItext\fR
Search for \fItext\fR in the given package manager\'s list\.
.TP
\fBsh\fR [\fB\-\-env=std\fR]
Instantiate a Homebrew build environment\. Uses our years\-battle\-hardened Homebrew build logic to help your \fB\./configure && make && make install\fR or even your \fBgem install\fR succeed\. Especially handy if you run Homebrew in an Xcode\-only configuration since it adds tools like \fBmake\fR to your \fBPATH\fR which otherwise build\-systems would not find\.
\fBstyle\fR [\fB\-\-fix\fR] [\fB\-\-display\-cop\-names\fR] [\fIfiles\fR|\fItaps\fR|\fIformulae\fR]
Check formulae or files for conformance to Homebrew style guidelines\.

Symlink all of the specific \fIversion\fR of \fIname\fR\'s install to Homebrew prefix\.
.TP
\fBtap\fR
List all installed taps\.
.TP
\fBtap\fR [\fB\-\-full\fR] \fIuser\fR\fB/\fR\fIrepo\fR [\fIURL\fR]
Tap a formula repository\.
.IP
With \fIURL\fR unspecified, taps a formula repository from GitHub using HTTPS\. Since so many taps are hosted on GitHub, this command is a shortcut for \fBtap <user>/<repo> https://github\.com/<user>/homebrew\-<repo>\fR\.
.IP
With \fIURL\fR specified, taps a formula repository from anywhere, using any transport protocol that \fBgit\fR handles\. The one\-argument form of \fBtap\fR 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\.
By default, the repository is cloned as a shallow copy (\fB\-\-depth=1\fR), but if \fB\-\-full\fR is passed, a full clone will be used\. To convert a shallow copy to a full copy, you can retap passing \fB\-\-full\fR without first untapping\.
.
.IP
\fBtap\fR is re\-runnable and exits successfully if there\'s nothing to do\. However, retapping with a different \fIURL\fR will cause an exception, so first \fBuntap\fR if you need to modify the \fIURL\fR\.
\fBtap\fR \fB\-\-repair\fR
Migrate tapped formulae from symlink\-based to directory\-based structure\.
\fBtap\fR \fB\-\-list\-official\fR

Remove symlinks for \fIformula\fR from the Homebrew prefix\. This can be useful for temporarily disabling a formula: \fBbrew unlink foo && commands && brew link foo\fR\.
.
.IP
If \fB\-\-dry\-run\fR or \fB\-n\fR is passed, Homebrew will list all files which would be unlinked, but will not actually unlink or delete any files\.
\fBunlinkapps\fR [\fB\-\-local\fR] [\fB\-\-dry\-run\fR] [\fIformulae\fR]
Remove symlinks created by \fBbrew linkapps\fR from \fB/Applications\fR (deprecated)\.
.
.IP
Unfortunately \fBbrew linkapps\fR cannot behave nicely with e\.g\. Spotlight using either aliases or symlinks and Homebrew formulae do not build "proper" \fB\.app\fR bundles that can be relocated\. Instead, please consider using \fBbrew cask\fR and migrate formulae using \fB\.app\fRs to casks\.
If no \fIformulae\fR are provided, all linked apps will be removed\.

\fBupdate\fR [\fB\-\-merge\fR] [\fB\-\-force\fR]
Fetch the newest version of Homebrew and all formulae from GitHub using \fBgit\fR(1) and perform any necessary migrations\.
If \fB\-\-merge\fR is specified then \fBgit merge\fR is used to include updates (rather than \fBgit rebase\fR)\.
.
.IP
If \fB\-\-force\fR is specified then always do a slower, full update check even if unnecessary\.
\fBupgrade\fR [\fIinstall\-options\fR] [\fB\-\-cleanup\fR] [\fB\-\-fetch\-HEAD\fR] [\fIformulae\fR]
Upgrade outdated, unpinned brews\.

.SH "CUSTOM EXTERNAL COMMANDS"
Homebrew, like \fBgit\fR(1), supports external commands\. These are executable scripts that reside somewhere in the \fBPATH\fR, named \fBbrew\-\fR\fIcmdname\fR or \fBbrew\-\fR\fIcmdname\fR\fB\.rb\fR, which can be invoked like \fBbrew\fR \fIcmdname\fR\. 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: \fIhttp://docs\.brew\.sh/External\-Commands\.html\fR
.SH "SPECIFYING FORMULAE"
Many Homebrew commands accept one or more \fIformula\fR arguments\. These arguments can take several different forms:
.
.TP
The name of a formula
e\.g\. \fBgit\fR, \fBnode\fR, \fBwget\fR\.
.
.TP
The fully\-qualified name of a tapped formula
Sometimes a formula from a tapped repository may conflict with one in \fBhomebrew/core\fR\. You can still access these formulae by using a special syntax, e\.g\. \fBhomebrew/dupes/vim\fR or \fBhomebrew/versions/node4\fR\.
.
.TP
An arbitrary URL
Homebrew can install formulae via URL, e\.g\. \fBhttps://raw\.github\.com/Homebrew/homebrew\-core/master/Formula/git\.rb\fR\. The formula file will be cached for later use\.
\fBAWS_ACCESS_KEY_ID\fR, \fBAWS_SECRET_ACCESS_KEY\fR
When using the \fBS3\fR download strategy, Homebrew will look in these variables for access credentials (see \fIhttps://docs\.aws\.amazon\.com/cli/latest/userguide/cli\-chap\-getting\-started\.html#cli\-environment\fR to retrieve these access credentials from AWS)\. If they are not set, the \fBS3\fR download strategy will download with a public (unsigned) URL\.

.TP
When \fBbrew install \-d\fR or \fBbrew install \-i\fR drops into a shell, \fBHOMEBREW_DEBUG_PREFIX\fR will be set to the target prefix in the Cellar of the formula being brewed\.
If set, Homebrew will tweak behaviour to be more relevant for Homebrew developers (active or budding) e\.g\. turning warnings into errors\.
If set, Homebrew will use this editor when editing a single formula, or several formulae in the same directory\.
\fINote:\fR \fBbrew edit\fR will open all of Homebrew as discontinuous files and directories\. TextMate can handle this correctly in project mode, but many editors will do strange things in this case\.
\fBHOMEBREW_FORCE_VENDOR_RUBY\fR
If set, Homebrew will always use its vendored, relocatable Ruby 2\.0 version even if the system version of Ruby is >=2\.0\.
.
.TP
A personal access token for the GitHub API, which you can create at \fIhttps://github\.com/settings/tokens\fR\. If set, GitHub will allow you a greater number of API requests\.
