要求：
把binlog日志 中2016年1月12日的delete语句提取出来 供恢复数据
 
脚本如下：
#!/bin/bash

#bl表列数 #语句yj
bl=4
yj=DELETE
zs1=`awk '/#160112/,/#160113/ {print $0}' /tmp/delete|awk '"/$yj/",/# at/ {print $0}'|grep ^###|grep "@"|cut -d"=" -f2`
zs2=`echo $zs1|awk '{print NF}'`
zt=`echo "$zs2/$bl"|bc`
hs=0

databa=gz
tab=wubx
ztt=$(($zt+0))
ii=0

a1=1
a2=2
a3=3
a4=4
  while [[ $ii -lt $ztt ]];do
l1=`echo $zs1|awk '{print $'"$a1"'}'`
l2=`echo $zs1|awk '{print $'"$a2"'}'`
l3=`echo $zs1|awk '{print $'"$a3"'}'`
l4=`echo $zs1|awk '{print $'"$a4"'}'`
echo "use $databa;insert into $tab values($l1,$l2,$l3,$l4)" >>hf
  
a1=$(($a1+$bl))
a2=$(($a2+$bl))
a3=$(($a3+$bl))
a4=$(($a4+$bl))

ii=$(($ii+1));
  done
 
运行结果：
oracle@gmcc-oracle:~> sh mysql.sh && cat hf
use gz;insert into wubx values(1,'gaoquan',22,'male')
use gz;insert into wubx values(2,'son',22,'male')
use gz;insert into wubx values(3,'gaoquan1',32,'male')

总结：初步写一个提取delete语句脚本，还有需要改进的地方，欢迎提出意见，共同探讨。
