1 TEE 命令说明

在Oracle 的SQLPLUS 工具中我们可以执行spool来记录操作内容，在MySQL中，可以使用tee工具来实现。
Linux tee 命令用于读取标准输入的数据，并将其内容输出成文件。tee 指令会从标准输入设备读取数据，将其内容输出到标准输出设备，同时保存成文件。http://www.cndba.cn/dave/article/131452

命令帮助：

[dave@www.cndba.cn:~]# tee --help
用法：tee [选项]... [文件]...
将标准输入复制到每个指定文件，并显示到标准输出。

  -a, --append          内容追加到给定的文件而非覆盖
  -i, --ignore-interrupts       忽略中断信号
      --help            显示此帮助信息并退出
      --version         显示版本信息并退出
