Some formulae in homebrew/core
are made available as versioned formulae using a special naming format, e.g. gcc@9
. If the version you’re looking for isn’t available, consider using brew extract
.
brew unlink <formula>
This can be useful if a package can’t build against the version of something you have linked into Homebrew’s prefix.
And of course, you can simply brew link <formula>
again afterwards!
Sometimes it’s faster to download a file via means other than the strategies that are available as part of Homebrew. For example, Erlang provides a torrent that’ll let you download at 4–5× compared to the normal HTTP method.
Downloads are saved in the downloads
subdirectory of Homebrew’s cache directory (as specified by brew --cache
, e.g. ~/Library/Caches/Homebrew
) and renamed as <url-hash>--<formula>-<version>
. The command brew --cache --build-from-source <formula>
will print the expected path of the cached download, so after downloading the file, you can run mv the_tarball "$(brew --cache --build-from-source <formula>)"
to relocate it to the cache.
You can also pre-cache the download by using the command brew fetch <formula>
which also displays the SHA-256 hash. This can be useful for updating formulae to new versions.
brew sh # or: eval "$(brew --env)"
gem install ronn # or c-programs
This imports the brew
environment into your existing shell; gem
will pick up the environment variables and be able to build. As a bonus, brew
’s automatically determined optimization flags are set.
brew install --only-dependencies <formula>
$ brew irb

export HOMEBREW_NO_EMOJI=1
This sets the HOMEBREW_NO_EMOJI
environment variable, causing Homebrew to hide all emoji.
The beer emoji can also be replaced with other character(s):
export HOMEBREW_INSTALL_BADGE="☕️ 🐸"
Running brew bundle dump
will record an installation to a Brewfile
and brew bundle install
will install from a Brewfile
. See brew bundle --help
for more details.
Run brew install --cask
with the --adopt
switch:
$ brew install --cask --adopt textmate
==> Downloading https://github.com/textmate/textmate/releases/download/v2.0.23/TextMate_2.0.23.tbz
...
==> Installing Cask textmate
==> Adopting existing App at '/Applications/TextMate.app'
==> Linking Binary 'mate' to '/opt/homebrew/bin/mate'
🍺 textmate was successfully installed!
Brewfile adds Ruby syntax highlighting for Homebrew Bundle Brewfile
s.
Brew Services is an extension for starting and stopping Homebrew services.
homebrew-mode provides syntax highlighting for inline patches as well as a number of helper functions for editing formula files.
pcmpl-homebrew provides completion for emacs shell-mode and eshell-mode.
In the macOS Terminal, you can right-click on a command name (like ls
or tar
) and pop open its manpage in a new window by selecting “Open man Page”.
Terminal needs an extra hint on where to find manpages installed by Homebrew because it doesn’t load normal dotfiles like ~/.bash_profile
or ~/.zshrc
.
sudo mkdir -p /usr/local/etc/man.d
echo "MANPATH /opt/homebrew/share/man" | sudo tee -a /usr/local/etc/man.d/homebrew.man.conf
If you’re using Homebrew on macOS Intel, you should also fix permissions afterwards with:
sudo chown -R "${USER}" /usr/local/etc
