感謝stackoverflow的幫助，我得到了下面的命令。但"match a single character not present in the set"不像我預期的那樣作業。第一次捕獲([^"][^\n,]*)應在",或處停止"\n，但目前僅在 處停止",\n。我的錯誤是什么，我該如何解決？
解決方案只能在 linux bash 上的 sed 中，理想情況下盡可能接近我當前的命令（以便我更容易理解）。
sed -En ':a;N;s/.*CAKE_FROSTING\(\n*?\s*?"([^"][^\n,]*)"[\n,]?\s*"?(([^"][^\n,]*)?")?.*,/\1\3/p;ba' filesToCheck/*

使用 GNUsed
$ sed -En ':a;N;s/.*CAKE_FROSTING\(\n*?\s*?"([^"][^\n,]*)"[\n,]?\s*"?(([^"][^\n,]*)?")?.*,[^\n]*/\1\3/p;ba' input_file
