Homebrew のキャッシュが思いのほか大きかったのでクリーンアップした

More than 1 year has passed since last update.

Homebrew でソフトウェアをアップデートすると,アップデート前のファイルも残っていてそれが結構な大きさになっているらしい




cleanup [--prune=days] [--dry-run] [-s] [formulae]
For all installed or specific formulae, remove any older versions from the cellar. In addition, old down-
loads from the Homebrew download-cache are deleted.

If --prune=days is specified, remove all cache files older than days.

If --dry-run or -n is passed, show what would be removed, but do not actually remove anything.

If -s is passed, scrubs the cache, removing downloads for even the latest versions of formulae. Note down-
loads for any installed formulae will still not be deleted. If you want to delete those too: rm -rf $(brew


$ brew cleanup
