命令行将所有图像的视网膜显示扩展名添加到文件夹中

Question

What's the command line to add a retina display extension (@2x) to all images into specific folder : Ex : eximg.png -> eximg@2x.png

Thanks in advance.

Answer 1

如果文件名包含空格或特殊字符，这也适用：

for f in *.png; do mv "$f" "${f%.png}@2x.png"; done

Answer 2

if your filename doesn't have special letters (eg spaces), this line will print those mv cmd for you:

 ls *.png|xargs -n1|sed -r 's/(.*)(.png)$/mv & \1@2x\2/'

and if all those commands are ok, you could pipe the output to |sh to rename your files.

Edit

 ls *.png|xargs -n1|sed 's/\(.*\)\(.png\)$/mv & \1@2x\2/'
