macOS命令"diskutil apfs列表“中的特定字段

Question

希望能就这一问题提供投入。我有来自macOS (High；FileSystem :APFS)命令- diskutil apfs list的输出。样本输出如下：

我的目标是：

1. 输出磁盘容器和GUID，用于fileVault状态为“是(锁定)”。
2. 将fileVault状态的GUID“是(锁定)”存储到变量中。

我想出了以下几点：

diskutil apfs list|awk '/[A-Z0-9]{8}-([A-Z0-9]{4}-){3}[A-Z0-9]{12}$|.l/{print}'

输出：

+-- Container disk5 1B5FE22B-6F4F-4EB9-8AA3-D326E4E940DF

转换结构化XML输出的马克·普罗尼克的建议。

diskutil apfs list -plist

转换为JSON并使用jq解析它。jq实用程序可以从macOS上的Homebrew中获得。

这必须分两个步骤完成，因为plutil需要读取一个常规文件：

diskutil apfs list -plist >list.xml
plutil -convert json -o list.json list.xml

从生成的JSON文件中，我们可以提取已启用FileVault并已锁定的所有卷的APFS卷UUID，使用

jq -r '.Containers[].Volumes[] | select(.FileVault == true and .Locked == true) | .APFSVolumeUUID' list.json

在一个“单一”命令中，将其赋值给一个变量：

locked_uuids=$(
    diskutil apfs list -plist >list.xml
    plutil -convert json -o list.json list.xml
    jq -r '.Containers[].Volumes[] | select(.FileVault == true and .Locked == true) | .APFSVolumeUUID' list.json
    rm -f list.xml list.json
)

请注意，上面的命令覆盖和删除当前目录中的两个文件list.xml和list.json。您可能希望使用mktemp创建临时文件：

locked_uuids=$(
    tmpxml=$(mktemp)
    tmpjson=$(mktemp)
    diskutil apfs list -plist >"$tmpxml"
    plutil -convert json -o "$tmpjson" "$tmpxml"
    jq -r '.Containers[].Volumes[] | select(.FileVault == true and .Locked == true) | .APFSVolumeUUID' "$tmpjson"
    rm -f "$tmpxml" "$tmpjson"
)

为了方便起见，您可能希望将这些命令放入一个shell函数中，然后调用它(在这里使用bash )：

list_locked_vaults () {
    local tmpxml=$(mktemp)
    local tmpjson=$(mktemp)
    diskutil apfs list -plist >"$tmpxml"
    plutil -convert json -o "$tmpjson" "$tmpxml"
    jq -r '.Containers[].Volumes[] | select(.FileVault == true and .Locked == true) | .APFSVolumeUUID' "$tmpjson"
    rm -f "$tmpxml" "$tmpjson"
}

locked_uuids=$( list_locked_vaults )
