線上圖片批量更換腳本記錄

 

需求說明：
線上以前使用的圖片沒有通過處理，比較大。應產品同事要求，將圖片拿出來處理後再替換以前的圖片，圖片名不變。

/tmp/image目錄下存放的修改後的圖片
[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/，修改後的圖片都有存放到這裏
好比：注意find命令中的目標目錄後面必定要加上/（好比下面的.../upload/，不能寫成.../upload，不然查找不到）

[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 ~]# 

那麼修改後的圖片批量替換以前的圖片的腳本以下：

#!/bin/bash
for m in `ls -l /tmp/image|awk -F" " '{print $9}'`
do
   for i in `cat /tmp/b.txt`
   do 
       for n in `ls "$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
          fi
       done
   done
done

腳本解刨以下：

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