Macで日常的にお仕事しているのは、ChromeブラウザとiTermとVSCodeが多いので、USBメモリを取り出すためにFinderを起動するのもめんどくさい。
iTermでコマンド入力してUSBメモリを取り出せると嬉しいのです。
で、「mac usb 取り出し コマンド」みたいな感じでぐぐってみると
MacではUSBメモリのアイコンを選択した状態で「Commandキー＋E」を押下すると、USBメモリを安全に取り外すことができます。
と教えてくれます。
そのアイコンをマウスで選択するのがめんどくさいんですけど。
「mac usb eject cli」でぐぐると見つかりました。
diskutilコマンドを使えばいいみたいです。
コマンドがわかったら、とりあえずそこのコマンドを動かしてみます。

とりあえず list を使ってみます。

disk7がUSBメモリですね。
% diskutil eject /dev/disk7 Disk /dev/disk7 ejected
iTermからのコマンドでUSBメモリを取り出せました。
