brew

Sets up Homebrew's environment (brew shellenv, sbin on PATH, completions) and adds two-to-five-letter aliases for the whole brew surface. On this setup Homebrew is Brewfile-driven: ~/.Brewfile (source: dot_Brewfile) is the single source of truth, installed by brew bundle --global — which chezmoi runs automatically on chezmoi apply.

Alias	Runs
bi / bcin	brew install / brew install --cask
bubo	brew update && brew outdated
bubu	bubo then brew upgrade
bsl / bson / bsoff	brew services list / start / stop
bcn	brew cleanup

Pro tips

• Don't bi and walk away. A bare brew install works today but never propagates to the other machines and won't survive a rebuild. Add a brew "name" line to dot_Brewfile in the chezmoi source, run chezmoi apply, done — that's the whole workflow.
• bubo before bubu — see what's outdated before upgrading. Blind bubu mid-week has shuffled tool versions under running work before; gitleaks in particular gates every commit, so if a hook starts failing after an upgrade, brew bundle --global restores the Brewfile world.
• brews (function, not alias) shows leaves with their dependents plus casks — the quickest "what did I actually ask for vs. what came along" audit, and a good diff against the Brewfile.
• ba (brew autoremove) after uninstalls keeps orphaned deps from accumulating; pair with bcn to reclaim disk.
• bsl is worth memorizing — launchd-managed services (databases, daemons) surface here, not in ps.
