这是一个 github 上的项目，挺简单实用的，用命令行下载 bing 的壁纸替换为 Mac 的壁纸。虽然不够优雅但胜在简单，记录过来。出处：https://github.com/xiqishow/bing_wallpaper
#!/usr/bin/env bash
#创建壁纸目录
echo $
if [[ $1 = "-n" ]]
then
osascript -e "display notification \"开始更换壁纸\" with title \"定时换壁纸\""
fi
mkdir -p ~/bing-wallpapers/
cd ~/bing-wallpapers/
#请求一个随机数(bing只能返回0到7)
index_seed="$(jot -r 1 0 7)"
#请求bing服务获得最新一张壁纸(下载UHD壁纸)
rurl_esult="$(curl --location --request GET 'http://www.bing.com/HPImageArchive.aspx?idx='$index_seed'&n=5&format=js' --header 'User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.71 Safari/537.36' | grep -o '"url":"[^"]*"' | sed -e 's/"url":"/https:\/\/cn.bing.com/' | sed -e 's/"//' | sed -e 's/1920x1080/UHD/g')"
#下载壁纸
rm -f wallpapler*.jpg
#随机文件名，否则无法更换壁纸
file_seed="$(date +%s)"
curl $rurl_esult -o wallpapler_$file_seed.jpg > /dev/null
#设置壁纸路径
localpath="/Users/$USER/bing-wallpapers/wallpapler_$file_seed.jpg"
#设置壁纸
# osascript -e "tell application \"Finder\" to set desktop picture to POSIX file \"$localpath\""
osascript -e "tell application \"System Events\" to set picture of (reference to every desktop) to \"$localpath\""
#提示壁纸设置成功
if [[ $1 = "-n" ]]
then
osascript -e "display notification \"壁纸更换成功\" with title \"定时换壁纸\""
fi
保存为一个文件（假设为 w.sh），chmod +x w.sh，
运行如下脚本（设置为定时任务，每5分钟1 次)：
#!/usr/bin/env bash
cFolder="$(pwd)"
echo "*/5 * * * * $cFolder/w.sh > /dev/null 2>&1" | crontab
