ImageMagic:
1.convert -resize 520x460 /photo/1.JPG /photo/result/6.jpg

做.sh文件
chmod +x filename 这样才能用./filename 来运行

dos2unix imageMagicToSmall.sh

执行压缩:
./imageMagicToSmall.sh /photo/3.gif /photo/result/3.gif


/

imageMagicToSmall.sh:

if ( test "$2" ) then
  echo "two args"
 echo "$1"
 echo "$2"
 date
  convert -resize 520x460 "$1" "$2"
  date
else
 echo "no arg"
fi

ImageMagick安装起来也相当方便,ImageMagick的包,,打包下载后运行:

tar zxvf imagemagick.tar.gz
cd ImageMagick-xx-xx
./configure --prefix=/usr/local/ImageMagick
make && make install
export PATH=$PATH:/usr/local/ImageMagick/bin

/


/

#!/bin/sh
startTime=`date "+%Y-%m-%d %H:%M:%S"`
echo "start time is $startTime"

notice: startTime于等号(=)不能有空格的 ,后面也一样的
