复合 mdfind 搜索

目标是查找某个州或国家/地区的所有图像。

mdfind kind:image

会找到所有图像

mdfind "kMDItemCountry == 'United States'"

将找到具有此属性的所有文件。

mdfind kind:image "kMDItemCountry == 'United States'" 

失败。我尝试过使用 && 和 () 的各种分组，但无法使其工作。如何成功地将“kind:image”与 kMDIxxx 等属性搜索结合起来？

我有机会做了一些实验mdfind真正有效，而不是它的记录方式 - 两者是不同的。

首先，让我们看一下名为的文件的 Spotlight 数据tardis.png我的 Mac 上一直挂着它。

mdls tardis.png

这是匹配并列出该文件的查询：

mdfind -onlyin . "(kMDItemPixelHeight>1500 || kMDItemPixelWidth=1400)&& kMDItemKind='*image*' && kMDItemProfileName='srgb*'c"

这展示了如何进行复合搜索&&（和）和||(OR)，如何将括号内的条件分组(conditionA || conditionB)以及如何进行不区分大小写的搜索（通过附加c在搜索字符串之后）。

Examples: 也许更多供我自己参考;-)

列出我在 Mac 上用于制作图片的所有相机和扫描仪：

mdfind -0 kind:image |  xargs -0 mdls -n kMDItemAcquisitionModel | sort -u
kMDItemAcquisitionModel = "645 PRO Mk III for iOS"
kMDItemAcquisitionModel = "BlackBerry 8900"
kMDItemAcquisitionModel = "BlackBerry 9000"
kMDItemAcquisitionModel = "Canon EOS 5D Mark III"
kMDItemAcquisitionModel = "Canon EOS 5D"
kMDItemAcquisitionModel = "Canon EOS 7D Mark II"
kMDItemAcquisitionModel = "Canon EOS 7D"
kMDItemAcquisitionModel = "Canon EOS-1D Mark II N"
kMDItemAcquisitionModel = "Canon EOS-1D Mark IV"
kMDItemAcquisitionModel = "Canon EOS-1D X"
kMDItemAcquisitionModel = "Canon EOS-1DS"

kMDItemAcquisitionModel = "iPad mini"
kMDItemAcquisitionModel = "iPad"
kMDItemAcquisitionModel = "iPhone 3G"
kMDItemAcquisitionModel = "iPhone 3GS"
kMDItemAcquisitionModel = "iPhone 4"
kMDItemAcquisitionModel = "iPhone 4S"
kMDItemAcquisitionModel = "iPhone 5"
kMDItemAcquisitionModel = "iPhone 5s"
kMDItemAcquisitionModel = "iPhone 6"
kMDItemAcquisitionModel = "iPhone 6s"
kMDItemAcquisitionModel = "iPhone SE"
kMDItemAcquisitionModel = "iPhone"

查找用 iPhone 6 拍摄的所有照片：

mdfind "kMDItemAcquisitionModel='*iPhone*6*'"

Notes:

• 手册页说-onlyin将搜索范围限制到指定目录。这实际上并不正确，因为它也会递归到包含的目录中。

• 是否使用单个（=) 或双 (==) 比较中的等号。

• 文档说你可以使用string==[c]"pattern"对于不区分大小写的搜索，这是不正确的，我上面显示的语法至少在 macOS Sierra 上有效。
