图片批处理改名

#循环所有jpg图片，转换为 70x100 大小并改名为 _thumb.xxxx 的形式。filebrowser 手工 thumbnailer 太慢了…

for img in `ls *.jpg`; do convert  -resize 70x100 ${img} miao.${img}; done

#批处理目录
for dir in `ls`; do cd ${dir};ls; for img in `ls *.jpg`; do convert -resize 70×100 ${img} _thumb.${img}; done; cd ..; done

for d in `ls`;do cd ${d};for dir in `ls`; do cd ${dir};ls; for img in `ls *.jpg`; do convert -resize 70×100 ${img} _thumb.${img}; done; cd ..; done;cd ..;done;
