统计mysql库中每张表的行数据

• 修改数据库配置文件：vim /etc/my.cnf

[client]
user=username
password=password

• 使用shell脚本统计表中的行数据:count.sh

#!/bin/bash
dbname=test
ip=192.168.1.100
for i in `mysql  -h$ip  -e "show tables from $dbname;" |  egrep -v "\||Tables_in_$dbname"`
do
        sleep 1
        count=`mysql  -h$ip -e "select count(1) from $dbname.$i" |grep -v "count"| awk -F "[ ]" "{print $1}"`
        echo  $i=$count >>/root/mysql.log
done

• 使用awk取出大于100行的表

cat /root/mysql.log | awk -F '[=]' '{if($2>100){print $0}}'
