20 do
21   $dump $dbname|gzip >${path}/${dbname}_$(date +%F).sql.gz
22   sleep 1
23   if [ -s ${path}/${dbname}_$(date +%F).sql.gz ];then
24      action "dump $dbname success!" /bin/true
25   else
26      action "dump $dbname failed" /bin/false
27   fi
28 done

29 }
30 function main(){
31 jdir
32 bk
33 }
34 main

想和大家重点分享的是开发的思路，技术很基础。

经过测试可以完成，如果有错误，欢迎指正。
