在Linux下有一個script工具，可以將當前終端會話中的所有輸入輸出結果捕獲到一個指定的文件裡。
看一下這個工具的man輸出：
[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.
當然最重要的是看一下實際效果。
在記錄操作前執行 script 命令開始記錄，最後輸入 exit 退出記錄，中間的所有操作都會被記錄下來，以下是一個測試過程，中間步驟被省略：
[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
現在讓我們來看看記錄文件typescript中記錄了什麼內容：
[oracle@jumper Oracle]$ cat typescript
Script started on Thu 26 Jun 2008 07:56:18 AM CST
[oracle@jumper Oracle]$ sqlplus "/ as sysdba"

這個工具是不是很有用途呢?
當然還有更強悍的 scriptreplay 工具可以replay script，不過缺省一般不帶，不說了。
