你可以使用awk命令的字符串处理功能来提取需要的内容。以下是一个示例命令：
”`shell
echo “{\“description\”:\“By Mahjong404Studio\”,\“external_url\”:\“\”,\“name\”:\“0xMJ404\”,\“attributes\”:[{\“trait_type\”:\“BG\”,\“value\”:\“Power Tower\”},{\“trait_type\”:\“WALL\”,\“value\”:\“Wood Color\”},{\“trait_type\”:\“LOBBY WINDOWS\”,\“value\”:\“All Vending Machines\”},{\“trait_type\”:\“DOOR\”,\“value\”:\“Wood Grain\”},{\“trait_type\”:\“UPPER WINDOWS\”,\“value\”:\“Upper Window 10\”},{\“trait_type\”:\“SIGN\”,\“value\”:\“Origami Crane\”},{\“trait_type\”:\“FACTION\”,\“value\”:\“Paa Man\”},{\“trait_type\”:\“ROOF\”,\“value\”:\“Pink Roof\”},{\“trait_type\”:\“LEFT\”,\“value\”:\“Kitchenware\”},{\“trait_type\”:\“RIGHT\”,\“value<br/>
