图片批量压缩大小脚本分享

压缩图片时用的一个脚本，先安装下#ImageMagick#

#!/bin/bash

# yum install ImageMagick

# cd /img/dir

for file in */*.jpg; do
to_middle_file="${file%.*}_m.${file##*.}"; //文件名加后缀如 hello_m.jpg
to_small_file="${file%.*}_s.${file##*.}";
convert ${img} -resize 300x180! ${to_middle_file};
ls ${to_middle_file};
convert ${img} -resize 100x60! ${to_small_file};
ls ${to_small_file};
done

# convert resize argument
# 100x200       # width = 100, height = 200
# 300x          # width = 300, height = proportional
# x300          # width = proportional, height = 300
# ! 表示强制转换大小,不加“!”会按照原图片比例压缩图片
