默认壁纸下载到 /tmp 里

其中，fd 和 xidel 命令是个人偏好，可以换成更通用的 find 和 jq

2

能把元数据 例如bing的照片说明 以及作者 放进文件名里吗

3

可以的，说明和作者应该是在 copyright 里

把 `local filename="bing_${date}_${title}.jpg"` 这一行改成 local filename="bing_${date}_${title}_${copyright}.jpg

如果 copyright 里有特殊字符，需要自己处理一下

@依云 代码段如何开启行号？:slightly_frowning_face:

不支持吧。
