.
.SH "NAME"
\fBbrew\fR \- The missing package manager for OS X
.
.SH "SYNOPSIS"
\fBbrew\fR [\-\-verbose|\-v] command [options] [formula] \.\.\.
.
.br
\fBbrew\fR [\-\-version|\-v]
.
.SH "DESCRIPTION"
Homebrew is the easiest and most flexible way to install the UNIX tools Apple didn\'t include with OS X\.
.
.SH "OPTIONS"
.
.TP
\fB\-v\fR, \fB\-\-verbose\fR command [options] [formula] \.\.\.
Prints extra, command\-specific debugging information\. Note that \fBbrew \-v\fR by itself is the same as \fBbrew \-\-version\fR\.
.
.SH "ESSENTIAL COMMANDS"
For the full command list, see the COMMANDS section\.
.
.TP
\fBinstall\fR \fIformula\fR
Install \fIformula\fR\.
.
.TP
\fBremove\fR \fIformula\fR
Uninstall \fIformula\fR\.
.
.TP
\fBupdate\fR
Fetch the newest version of Homebrew from GitHub using \fBgit\fR(1)\.
.
.TP
\fBlist\fR
List all installed formulae\.
.
.TP
\fBsearch\fR, \fB\-S\fR \fItext\fR|/\fItext\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\. If no search term is given, all available formula are displayed\.
.
.SH "COMMANDS"
.
.TP
\fBaudit [\-\-strict]\fR [\fIformulae\fR]
Check \fIformulae\fR for Homebrew coding style violations\. This should be run before submitting a new formula\.
.
.IP
If no \fIformulae\fR are provided, all of them are checked\.
.
.IP
If \fB\-\-strict\fR is passed, perform additional stricter checks that may not need to be fixed before submitting\.
.
.IP
\fBaudit\fR exits with a non\-zero status if any errors are found\. This is useful, for instance, for implementing pre\-commit hooks\.
.
.TP
\fBcat\fR \fIformula\fR
Display the source to \fIformula\fR\.
.
.TP
\fBcleanup [\-\-force]\fR [\fIformula\fR]
For all installed or specific formulae, remove any older versions from the cellar\. By default, does not remove out\-of\-date keg\-only brews, as other software may link directly to specific versions\.
.
.IP
If \fB\-\-force\fR is passed, remove out\-of\-date keg\-only brews as well\.
.
.TP
\fBcreate [\-\-no\-fetch]\fR \fIURL\fR
Generate a formula for the downloadable file at \fIURL\fR and opens it in $EDITOR\. Homebrew will attempt to automatically derive the formula name and version, if it fails, you\'ll have to make your own template\. I suggest copying wget\'s\.
.
.IP
If \fB\-\-no\-fetch\fR is passed, Homebrew will not download \fIURL\fR to the cache and will thus not add the MD5 to the formula for you\.
.
.TP
\fBdeps [\-\-1] [\-n]\fR \fIformula\fR
Show \fIformula\fR\'s dependencies\.
.
.IP
If \fB\-\-1\fR is passed, only show dependencies one level down, instead of recursing\.
.
.IP
If \fB\-n\fR is passed, shows dependencies in topological order\.
.
.TP
\fBdoctor\fR
Check your system for potential problems\.
.
.TP
\fBedit\fR
Open all of Homebrew for editing in TextMate\.
.
.TP
\fBedit\fR \fIformula\fR
Open \fIformula\fR in $EDITOR\.
.
.TP
\fBfetch [\-\-force] [\-v] [\-\-HEAD] [\-\-deps]\fR \fIformulae\fR
Download the source packages for the given \fIformulae\fR\. For tarballs, also print MD5 and SHA1 checksums\.
.
.IP
If \fB\-\-HEAD\fR is passed, download the HEAD versions of \fIformulae\fR instead\. \fB\-v\fR may also be passed to make the VCS checkout verbose, useful for seeing if an existing HEAD cache has been updated\.
.
.IP
If \fB\-\-force\fR is passed, remove a previously cached version and re\-fetch\.
.
.IP
If \fB\-\-deps\fR is passed, also download dependencies for any listed \fIformulae\fR\.
.
.TP

Install \fIformula\fR\.
.
.IP
\fIformula\fR is usually the name of the formula to install, but may also be the URL for an arbitrary formula\.
.
.IP
If \fB\-\-force\fR is passed, will install \fIformula\fR even if it is already installed\. This can be used to re\-install a formula without removing it first\.
.
.IP
If \fB\-\-debug\fR is passed and brewing fails, open a shell inside the temporary folder used for compiling\.
.
.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\.
.
.IP
If \fB\-\-use\-clang\fR is passed, attempt to compile using clang\.
.
.IP
If \fB\-\-use\-gcc\fR is passed, attempt to compile using GCC\. This is useful for systems whose default compiler is LLVM\-GCC\.

Some sample commands ship with Homebrew and are enabled by default\.
.
.IP "" 4

.SH "ENVIRONMENT"
.
.TP
HOMEBREW_CACHE
If set, instructs Homebrew to use the give folder as the download cache\. Otherwise, \fB~/Library/Caches/Homebrew\fR is used\.
.
.IP
This can be used to keep downloads out of your home folder, if you have it mounted on an SSD for instance\.
.
.TP
HOMEBREW_DEBUG
If set, instructs Homebrew to always assume \fB\-\-debug\fR when running commands\.
.
.TP
HOMEBREW_DEBUG_INSTALL
When \fBbrew install \-d\fR or \fBbrew install \-i\fR drops into a shell, \fBHOMEBREW_DEBUG_INSTALL\fR will be set to the name of the formula being brewed\.
.
.TP
HOMEBREW_DEBUG_PREFIX
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\.
.
.TP
HOMEBREW_EDITOR
If set, Homebrew will use this editor when editing a single formula, or several formulae in the same folder\.
.
.IP
\fINOTE\fR: \fBbrew edit\fR will open all of Homebrew as discontinuous files and folders\. TextMate can handle this correctly in project mode, but many editors will do strange things in this case\.
.
.TP
HOMEBREW_KEEP_INFO
If set, Homebrew will not remove files from \fBshare/info\fR, allowing them to be linked from the Cellar\.
.
.TP
HOMEBREW_SVN
When exporting from Subversion, Homebrew will use \fBHOMEBREW_SVN\fR if set, a Homebrew\-built Subversion if installed, or the system\-provided binary\.
.
.IP
Set this to force Homebrew to use a particular svn binary\.
.
.TP
HOMEBREW_TEMP
If set, instructs Homebrew to use \fBHOMEBREW_TEMP\fR as the temporary folder for building packages\. This may be needed if your system temp folder and Homebrew Prefix are on different volumes, as OS X has trouble moving symlinks across volumes when the target does not yet exist\.
.
.IP
This issue typically occurs when using FileVault or custom SSD configurations\.
.
.TP
HOMEBREW_USE_CLANG
If set, instructs Homebrew to compile using clang\.
.
.TP
HOMEBREW_USE_GCC
If set, instructs Homebrew to compile using gcc\.

.
.IP
\fINOTE\fR: Not all formulae build correctly with LLVM\.
.
.TP
HOMEBREW_VERBOSE
If set, instructs Homebrew to always assume \fB\-\-verbose\fR when running commands\.
.
.SH "USING HOMEBREW BEHIND A PROXY"
Homebrew uses several commands for downloading files (e\.g\. curl, git, svn)\. Many of these tools can download via a proxy\. It\'s common for these tools to read proxy parameters from environment variables\.
.
.P
For the majority of cases setting \fBhttp_proxy\fR is enough\. You can set this in your shell profile, or you can use it before a brew command:
.
.IP "" 4
.
.nf

http_proxy=http://<host>:<port> brew install foo
.
.fi
.
.IP "" 0
.
