如何使用单个`defaults`命令定义数组？

我想要一个域名 com.apple.keyboard.modifiermapping.1452-628-0 包含以下数组：

(
        {
        HIDKeyboardModifierMappingDst = 2;
        HIDKeyboardModifierMappingSrc = 0;
    },
        {
        HIDKeyboardModifierMappingDst = 0;
        HIDKeyboardModifierMappingSrc = 2;
    },
        {
        HIDKeyboardModifierMappingDst = 0;
        HIDKeyboardModifierMappingSrc = 10;
    }
)

我可以通过删除当前值并运行三个来实现它 -array-add 命令：

defaults -currentHost delete -g com.apple.keyboard.modifiermapping.1452-628-0
defaults -currentHost write -g com.apple.keyboard.modifiermapping.1452-628-0 -array-add '{ HIDKeyboardModifierMappingDst = 2; HIDKeyboardModifierMappingSrc = 0; }'    
defaults -currentHost write -g com.apple.keyboard.modifiermapping.1452-628-0 -array-add '{ HIDKeyboardModifierMappingDst = 0; HIDKeyboardModifierMappingSrc = 2; }'    
defaults -currentHost write -g com.apple.keyboard.modifiermapping.1452-628-0 -array-add '{ HIDKeyboardModifierMappingDst = 0; HIDKeyboardModifierMappingSrc = 10; }'
defaults -currentHost read -g com.apple.keyboard.modifiermapping.1452-628-0

我可以使用什么语法在单个命令中定义数组？

• 如果我运行以下脚本：

  defaults -currentHost delete -g com.apple.keyboard.modifiermapping.1452-628-0
  defaults -currentHost write -g com.apple.keyboard.modifiermapping.1452-628-0 -array '(
    { HIDKeyboardModifierMappingDst = 2; HIDKeyboardModifierMappingSrc = 0; },
    { HIDKeyboardModifierMappingDst = 0; HIDKeyboardModifierMappingSrc = 2; },
    { HIDKeyboardModifierMappingDst = 0; HIDKeyboardModifierMappingSrc = 10; } )' 
  defaults -currentHost read -g com.apple.keyboard.modifiermapping.1452-628-0
  

  我在一个数组中得到一个数组：

  (
          (
                  {
              HIDKeyboardModifierMappingDst = 2;
              HIDKeyboardModifierMappingSrc = 0;
          },
                  {
              HIDKeyboardModifierMappingDst = 0;
              HIDKeyboardModifierMappingSrc = 2;
          },
                  {
              HIDKeyboardModifierMappingDst = 0;
              HIDKeyboardModifierMappingSrc = 10;
          }
      )
  )
  

• 如果我尝试 -plist 代替 -array 我得到了 Unexpected argument。

• 如果我运行以下脚本：

  defaults -currentHost delete -g com.apple.keyboard.modifiermapping.1452-628-0    
  defaults -currentHost write -g com.apple.keyboard.modifiermapping.1452-628-0 -array '
    { HIDKeyboardModifierMappingDst = 2; HIDKeyboardModifierMappingSrc = 0; },
    { HIDKeyboardModifierMappingDst = 0; HIDKeyboardModifierMappingSrc = 2; },
    { HIDKeyboardModifierMappingDst = 0; HIDKeyboardModifierMappingSrc = 10; }'
  defaults -currentHost read -g com.apple.keyboard.modifiermapping.1452-628-0
  

  我收到语法错误 defaults[22044:679428] Could not parse: ... Try single-quoting it.

再次提问：我可以使用什么语法在单个命令中定义数组？

-array 将单个数组元素作为单独的参数。

defaults -currentHost write -g com.apple.keyboard.modifiermapping.1452-628-0 -array \
  '{ HIDKeyboardModifierMappingDst = 2; HIDKeyboardModifierMappingSrc = 0; }' \
  '{ HIDKeyboardModifierMappingDst = 0; HIDKeyboardModifierMappingSrc = 2; }' \
  '{ HIDKeyboardModifierMappingDst = 0; HIDKeyboardModifierMappingSrc = 10; }'

'\'用于保持shell等待下一行，因此如果写在一行上，它们可以省略。你不需要使用 delete 第一：不像 -array-add， -array 用新内容替换整个数组。

如果您不想这样做，可以选择以下方法：您可以将数据结构作为字符串传递。这更接近您问题中的示例，并且工作原理相同。

defaults -currentHost write -g com.apple.keyboard.modifiermapping.1452-628-0 '(
  { HIDKeyboardModifierMappingDst = 2; HIDKeyboardModifierMappingSrc = 0; },
  { HIDKeyboardModifierMappingDst = 0; HIDKeyboardModifierMappingSrc = 2; },
  { HIDKeyboardModifierMappingDst = 0; HIDKeyboardModifierMappingSrc = 10; } )'
