How to Capture a Unix Terminal Session?
 

Hi All,

I want to capture all the operations performed in the terminal. So to achieve this I used “script” command. This works as I expected. But this command captures all the standard output which is redirected to terminal. For example if i “tail” a file, even the tail output is getting captured. But I want to capture only the commands not the output. I don’t want to capture the Standard Output. Is there any way to capture only the commands that are typed in the terminal?

I don’t want use the bash history since it will not store TTY information. I have automated this process, whenever user logins a script will be started to capture the operations.

Thanks,
Kalai

You can tweak the HISTFILE variable in user's rc/profile to save the command history on terminal number basis of each user.

Have a look here?

Thanks a lot this helped me..
But in history file a date is getting updated along with each command. Is it possible to remove all other data except command.

One of the rules of safe(r) programming says you should never trust user-submitted input. So no, you should not trust or rely on settings or files if the user owns them and can modify them at will.
