需求说明：
线上之前使用的图片没有经过处理，比较大。应产品同事要求，将图片拿出来处理后再替换之前的图片，图片名不变。

线上图片存放的路径是/var/www/vhosts/www.fangfull.com/main/upload/，修改后的图片都有存放到这里
比如：注意find命令中的目标目录后面一定要加上/（比如下面的.../upload/，不能写成.../upload，否则查找不到）

'{print $9}'
`
do
for

`
cat

do
for

in
`
ls
"$i"

awk
-F
"/"
'{print $9}'
`
do
if
[ $m == $n ];
then
\
cp
-f
/tmp/image/
$m `
cat
/tmp/b
.txt|
grep
"$m"
`
else
echo
"123"

/dev/null
2>&1

done
done

脚本解刨如下：
