Homebrew を Macbook へインストールする際のステップです。
OS：Mac OS Catalina バージョン 10.15.4
Homebrew 公式サイトでインストール用スクリプトをコピー＆ターミナルへペースト
Homebrew の公式サイトへアクセス。
トップページに表示されているコードをコピーし、ターミナルへペースト＆「Enter」
*コードは 2020 年 5 月時点のものです。
~ % /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
インストールがスタート
するとまず下記の通りインストール時に何が起こるかの説明が表示されます。

Press RETURN to continue or any other key to abort
そのままリターンキーを叩くとパスワード確認後インストールへ。他のキーを叩くと切断されます。ということでリターンキーをポチ。

上記の最後の行、「Xcode 用のコマンドラインツールをダウンロードしています」で一旦止まりますがそのまま待ちます。
その後下記の様な表示がされます。

パスワードを入力すると再度処理が始まりズラズラっとターミナル上に表出されていきます。
「==> Installation successful!」と表示されてインストール完了

上記の中盤過ぎに「==> Installation successful!」と表示が出ているので問題なく処理が完了した様です。
「ターミナルで brew help と入力すればいくつか情報が得られるし、https://docs.brew.sh にもより詳細な情報があるよ」とのこと。ちなみに「brew help」を実行すると下記の内容が表示されます。
~ % brew help Example usage: brew search [TEXT|/REGEX/] brew info [FORMULA...] brew install FORMULA... brew update brew upgrade [FORMULA...] brew uninstall FORMULA... brew list [FORMULA...] Troubleshooting: brew config brew doctor brew install --verbose --debug FORMULA Contributing: brew create [URL [--no-fetch]] brew edit [FORMULA...] Further help: brew commands brew help [COMMAND] man brew https://docs.brew.sh
いまいちよく分からないですね！ひとまず一旦無視して追々必要に応じて調べていこうと思います。
「brew –version」で最終確認
ターミナルに「brew –version」と入力して Enter。ちゃんとどのバージョンがインストールされているか表示されています。ということでインストールはOKです。
