今天想看一下 Mac 上的 Preview app 的一些設定值，

因為用它來抓螢幕截圖的話，都會跑出一個陰影框，不是很喜歡，

但從 Preview 的 Preferences 設定那邊又沒得改…

 

查了一下，像 Preview 的一些設定值，

放在 ~/Library/Preferences/com.apple.Preview.plist，

這種 plist 檔直接 cat 都會是亂碼：

testuser@localhost ~/Library/Preferences $ cat ./com.apple.Preview.plist

bplist00_!NSNavPanelExpandedSizeForSaveMode_"NSNavPanelExpandedStateForSaveMode_NSNavLastRootDirectory_!NSNavPanelExpandedSizeForOpenModeZ{712, 557}	[~/DownloadsZ{720, 4485Zs����	�

 

要怎麼讀取 plist 檔案呢？

可以用 defaults 這個指令，像是 defaults read <plist file> 就可以顯示它的內容，

例如我想要顯示 com.apple.Preview 這個 .plist 的內容：

testuser@localhost ~/Library/Preferences $ defaults read com.apple.Preview

{
    NSNavLastRootDirectory = "~/Dropbox/Desktop";
    NSNavLastUserSetHideExtensionButtonState = 0;

如上，可以看到不少設定值，

不過似乎是沒有與截圖陰影有關的東西。

但至少學到了讀取 plist 檔案內容的方法啦～
