需求說明：
線上之前使用的圖片沒有經過處理，比較大。應產品同事要求，將圖片拿出來處理后再替換之前的圖片，圖片名不變。

/tmp/image目錄下存放的修改后的圖片
[root@kevin_web1 ~]# ls -l /tmp/image|head -10

線上圖片存放的路徑是/var/www/vhosts/www.kevin.com/main/upload/，修改后的圖片都有存放到這里
比如：注意find命令中的目標目錄后面一定要加上/（比如下面的.../upload/，不能寫成.../upload，否則查找不到）

[root@kevin_web1 ~]# find /var/www/vhosts/www.kevin.com/main/upload/ -name 201407281934401406547280.jpg /var/www/vhosts/www.kevin.com/main/upload/20140728/201407281934401406547280.jpg [root@kevin_web1 ~]# find /var/www/vhosts/www.kevin.com/main/upload -name 201407281934401406547280.jpg [root@kevin_web1 ~]#

那么修改后的圖片批量替換之前的圖片的腳本如下：

#!/bin/bash for m in `ls -l /tmp/image|awk -F" " '{print $9}'` dofor i in `cat /tmp/b.txt`do for n in `ls "$i"|awk -F"/" '{print $9}'`doif [ $m == $n ];then\cp -f /tmp/image/$m `cat /tmp/b.txt|grep "$m"`elseecho "123" > /dev/null 2>&1fidonedone done

腳本解刨如下：

[root@kevin_web1 ~]# ls -l /tmp/image|awk -F" " '{print $9}'|head -10
