Q. How can I save my input and output commands and see them when required in Linux?
A. At the beginning of the session if I will use SCRIPT command then the details of the input and output commands will be saved in a file called typescript and we can view it any time using “cat typescript” command.
This is very useful to track what user is doing what. HISTORY command will not work because it shows data only for the current session.
