system_profiler SPDisplaysDataType | grep Resolution
ユーティリティを使用しscreenresolution
て画面解像度を取得します。
$ /usr/local/bin/screenresolution get 2>&1 | grep -oE 'Display 0: [0-9]+' | grep -Eo '[0-9]+$'
1920
私が書いたdisplayplacerこれを助けることができ、。実行するdisplayplacer list
と、すべての画面の現在の解像度(および詳細情報)が表示されます。
$ displayplacer list

Resolutions for rotation 0:

grepは、出力を解析するための簡単なアプローチです。
$ displayplacer list | grep -e Resolution: -e Scaling:
Resolution: 3840x2160
Scaling:off
Resolution: 1680x1050
Scaling:on
