brew(1) -- The Missing Package Manager for macOS (or Linux)
===========================================================

## SYNOPSIS

`brew` `--version`<br>
`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 to your home directory without requiring `sudo`.

## TERMINOLOGY

**Formula**: The package definition

**Cask**: An extension of Homebrew to install macOS native apps

**Keg**: The installation prefix of a **Formula**

**Keg-only**: A **Formula** is **Keg-only** if it is not linked into the Homebrew prefix

**Cellar**: All **Kegs** are installed here

**Caskroom**: All **Casks** are installed here

**Tap**: A Git repository of **Formulae** and/or commands

**Bottle**: Pre-built **Keg** used instead of building from source

## 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.

### `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.

## 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:
<https://docs.brew.sh/External-Commands>

## 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`.

  * 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.

## SPECIFYING CASKS

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.

## 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`.

<%= environment_variables %>

## 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
