这个脚本的原型来自之前提到的db备份脚本，但做了一些改动略有不同。

这次的脚本支持逗号分隔的kv输入，具体输入文本格式如下

+------------------+--------------+----------------+
| folder full path | separator(,) | folder descript|
+------------------+--------------+----------------+
| /var/aaaaa/      |    ,         | aaaa11111      |
+------------------+--------------+----------------+

发送到邮箱的标题命名：web_bak_${folder descript}_${data}

具体shell代码如下：

#!/bin/bash
 
#need 2 var
if (($# != 2)); then
        echo "need input [Web Site Name Full Path in File] [mode]"
        echo "mode -> 0, <Web Site Name Full Path in File> read!"
        echo "mode -> 1, do Web Site bak!"
        exit;
fi
 
if (($2 < 0 && $2 > 1)); then
        echo "err mode!"
        exit
fi
 
#filter some lines:
# 1. pure tab line
# 2. pure \r\n
# 3. pure space line
WebSiteFullPathInFilePath=$1
sed /^[[:space:]]*$/d $WebSiteFullPathInFilePath > $WebSiteFullPathInFilePath".tmp"

同样作为定时任务，将命令执行放在crontab中
