ImageMagick和脚本批量压缩图片

ImageMagick，相关介绍请看点击打开链接，下面介绍安装及使用.

安装命令：

apt-get install imagemagick

下面的脚本是网上的大牛写的拿来用之（其实对学过shell编程的人来说真的很简单）：

#!/bin/bash
echo "resize image who is bigger than 100k";
for i in `find . -size +100k`;
do
convert $i -resize 50% $i;
echo "resize image $i to 50%";
done

接下来不要忘了加上执行权限resize.sh是脚本文件名

$ chmod +x resize.sh

执行测试：

root@test:~/Pictures/blog/DataStruct# ./resize.sh
resize image who is bigger than 100k
resize image ./C360_2014-10-17-11-32-13-930.jpg to 50%
resize image ./C360_2014-10-17-11-30-04-413.jpg to 50%
resize image ./C360_2014-10-17-11-30-48-445.jpg to 50%
resize image ./C360_2014-10-17-11-32-36-383.jpg to 50%
resize image ./C360_2014-10-17-11-32-48-951.jpg to 50%
resize image ./C360_2014-10-17-11-32-25-512.jpg to 50%
resize image ./C360_2014-10-17-11-31-14-194.jpg to 50%
resize image ./C360_2014-10-17-11-31-39-155.jpg to 50%
resize image ./C360_2014-10-17-11-29-36-626.jpg to 50%
resize image ./C360_2014-10-17-09-08-25-291.jpg to 50%

感觉用起来还可以，你值得拥有。
