概要

M1 MacBook Air を購入して約 1 週間。
LINE や Chorme など、普段使いとしては（すごーく丁寧に使いながら、）良い感じになってきた所、後輩に「Docker とか入れてないんですか？」と煽られた為、開発環境の構築。
最終的には AWS とか連携して iPadOS アプリを何か作りたい。

時間制限も無いのでドキュメントもしっかり読んで（当たり前）行きたいです。
Google 翻訳様、DeepL 様は多めに使っています。

うん、綺麗な感じです。

Homebrew 自体をアップデートしようと思うけど、実行するとバージョンがどうなるか確認したいのですが、わかりません。

検索途中で、

[Homebrew使い方まとめ]

とか拝見。
でも、cask とか指定方法が変わったものがある事は記憶しています。
この辺りはおいおい。

とりあえず、ドーン。

Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry or file an issue; just ignore this. Thanks!

Warning: You have uncommitted modifications to Homebrew/brew.
If this is a surprise to you, then you should stash these modifications.
Stashing returns Homebrew to a pristine state but can be undone
should you later need to do so for some reason.
