shell数据库关联文件处理

清除录音文件的脚本，在此博文中有介绍相关的数据结构http://blog.chinaunix.net/uid-27050514-id-3838897.html    考虑到有其它人员要操作，这个脚本增加了配置文件机制，以便让其它人员能更好的管理。脚本很简单，主是要增加了配置读取，每次取出符合条件的号码，再对每个号码对应的录音标识（seq）进行数据库操作及文件操作。主要提供一种思路，在运维过程中有很多类似的处理。

配置文件：

log=./log
#源目录
data=/home/wanggy/test_dir
#备份目录
topath=/home/wanggy/test_dir1
#mv 0,del 1
flag=0
#间隔时间(s)
interval=100
#处理多少天前的数据
days=10
#db
dbhost=192.168.1.14
dbuser=wanggy
dbpass=12345678
dbbase=gzy_call
