Answer 1

find ./ -iname "*.jpg.jpg" -exec rename .jpg.jpg .jpg '{}' \;

如果您有使用perl正则表达式的rename实用程序，请使用以下命令：

find ./ -iname "*.jpg.jpg" -exec rename 's/\.jpg\.jpg$/.jpg/' '{}' \;

Answer 2

May be you could use the inbuilt rename command.

rename 's/\.jpg\.jpg$/.jpg/' *.jpg.jpg

The first argument is a regular expression that would match filenames ending in .jpg.jpg and replace with .jpg . The second argument will look for files with .jpg.jpg format in the current directory.
