Assuming you're in folder a the following might work for you
假设您在文件夹 a 中，以下内容可能对您有用
find . -name "*.jpg" -exec mogrify -format png {} \;
You can use the find command to get all the jpg files in all the subfolders and pass your command as an argument to find
您可以使用 find 命令获取所有子文件夹中的所有 jpg 文件，并将您的命令作为参数传递给 find
