What kind of text --properties expect?
It is expecting JSON string in double quotation marks. So you have to put the value of $content inside the double quotation mark.
az datafactory dataset create --properties "{\"type\":\"AzureBlob\",\"linkedServiceName\":{\"type\":\"LinkedServiceReference\",\"referenceName\":\"exampleLinkedService\"},\"parameters\":{\"MyFileName\":{\"type\":\"String\"},\"MyFolderPath\":{\"type\":\"String\"}},\"typeProperties\":{\"format\":{\"type\":\"TextFormat\"},\"fileName\":{\"type\":\"Expression\",\"value\":\"#dataset().MyFileName\"},\"folderPath\":{\"type\":\"Expression\",\"value\":\"#dataset().MyFolderPath\"}}}" --name "exampleDataset" --factory-name "exampleFactoryName" --resource-group "exampleResourceGroup"
