A ton of data to import with a shell

Standard

schema_import.sh

#!/bin/bash
for f in *schema*.gz; do
  DBName=$(echo $f | cut -d - -f 5)
  echo "Create "${DBName}
  echo "create database if not exists ${DBName}" | /usr/bin/mysql -u root -pXXXXXX
  zcat ${f} | /usr/bin/mysql -u root -pXXXXXX ${DBName}
  echo "Created"
done

data_import.sh

#!/bin/bash
for f in *data*.gz; do
  DBName=$(echo $f | cut -d - -f 5)
  echo "Import "${DBName}
  zcat ${f} | /usr/bin/mysql -u root -pXXXXXX ${DBName}
  echo "Imported"
done

一大坨文件

ps:
公司收了一家美国的论坛服务商,那边留了个人交接.
放了个NFS,上去一看,好家伙.每台机器目录下有几千个小的备份文件.
问其why,答long story…
好吧…好在文件命名还算规律。
