在Linux下有一个script工具，可以将当前终端会话中的所有输入输出结果捕获到一个指定的文件里。

　　看一下这个工具的man输出：

　　[oracle@jumper oracle]$ which script

　　/usr/bin/script

　　[oracle@jumper oracle]$ man script

　　SCRIPT(1) BSD General Commands Manual SCRIPT(1)

　　NAME

　　script - make typescript of terminal session

　　SYNOPSIS

　　script [-a] [-f] [-q] [-t] [file]

　　DESCRIPTION

　　Script makes a typescript of everything printed on your terminal. It is

　　useful for students who need a hardcopy record of an interactive session

　　as proof of an assignment, as the typescript file can be printed out

　　later with lpr(1).

　　If the argument file is given, script saves all dialogue in file. If no

　　file name is given, the typescript is saved in the file typescript.

　　当然最重要的是看一下实际效果。

在记录操作前执行 script 命令开始记录，最后输入 exit 退出记录，中间的所有操作都会被记录下来，以下是一个测试过程，中间步骤被省略：

　　[oracle@jumper oracle]$ script

　　Script started, file is typescript

　　[oracle@jumper oracle]$ sqlplus "/ as sysdba"

　　<...ignore operation here...>

　　[oracle@jumper oracle]$ exit

　　Script done, file is typescript

　　现在让我们来看看记录文件typescript中记录了什么内容：

　　[oracle@jumper oracle]$ cat typescript

　　Script started on Thu 26 Jun 2008 07:56:18 AM CST

　　[oracle@jumper oracle]$ sqlplus "/ as sysdba"

　　这个工具是不是很有用途呢?

　　当然还有更强悍的 scriptreplay 工具可以replay script，不过缺省一般不带，不说了。
