Getting Started

Use local Brewfile

By default, Brewfile is ~/.config/brewfile/Brewfile.

If you don’t have Brewfile, first, do:

$ brew init

brew init is same as brew file init, if you setup brew-wrap as in Installation.

Note: In below, set_repo command can be used directly after brew, but install or update need to use with brew file because brew command has own install or update commands.

You can check your package list by:

$ brew file cat

If you already have Brewfile, then copy it to ~/.config/brewfile/Brewfile and install packages listed in Brewfile by:

$ brew file install

After that, you need to do only normal brew commands, like brew install or brew uninstall. After each command, Brewfile is updated automatically if you set brew-wrap as in Installation.

When you get new Mac, copy ~/.config/brewfile to new Mac and just do:

$ brew file install

Use Dropbox (or any online storages) for Brewfile management

Set Brewfile place

You can set the place of Brewfile by using the environment variable like:

export HOMEBREW_BREWFILE=~/Dropbox/Brewfile

Then, you can use Brewfile as same as the original Brewfile place.

In this case, when you have new Mac, set HOMEBREW_BREWFILE and synchronize the file with a online storage service, then do:

$ brew file install

If you are using multiple Mac in the same time, it is good to have a cron job like:

30 12 * * * brew file update

This command installs new packages which were installed in another Mac at a lunch time (12:30) every day.

This command also does brew update && brew upgrade, and removes packages not listed in Brewfile.

If you want to do only installing new packages, then set as:

30 12 * * * brew file install

Use GitHub (or any git repository) for Brewfile management

Set up a repository

First, create a repository with a file named Brewfile.

If you use GitHub, you can make it with brew-file:

$ brew set_repo

Set repository, "non" for local Brewfile.
<user>/<repo> for GitHub repository,
or full path for the repository:

Give a name like rcmdnk/Brewfile (will be recognized as a GitHub repository), or such git@github.com:rcmdnk/Brewfile.

Then, initialize Brewfile:

$ brew init

Set up new Mac with your Brewfile in the repository

Do:

$ brew set_repo

and give your repository name.

And install packages listed in Brewfile like:

$ brew file install

Brewfile management

To update the repository, do:

$ brew file update

If you have set the repository, this command does git pull and git push in addition to such brew’s install, clean, update, upgrade and removing packages described in online storages section above.

It is good if you have such a cron job like:

30 12 * * * brew file update

The repository is updated at lunch time every day.
