Using Homebrew

To install a package (or Formula in Homebrew vocabulary) simply type:

brew install <formula>

To update Homebrew's directory of formulae, run:

brew update

Note: If that command fails you can manually download the directory of formulas like this:

cd /usr/local/Homebrew/
git fetch origin
git reset --hard origin/master

To see if any of your formulas need to be updated:

brew outdated

To update a formula:

brew upgrade <formula>

Homebrew keeps older versions of formulas installed on your system, in case you want to roll back to an older version. That is rarely necessary, so you can do some cleanup to get rid of those old versions:

brew cleanup

If you want to see what formulae Homebrew would delete without actually deleting them, you can run:

brew cleanup --dry-run

To see what you have installed (with their version numbers):

brew list --versions

To search for formulas you run:

brew search <formula>

To get more information about a formula you run:

brew info <formula>

To uninstall a formula you can run:

brew uninstall <formula>
