It won't display the shell prompt. But it will display the commands and results. So if you want shell prompt as well, then using script is the best option.

Here is how you can use script command:-
Code:
script collect_log

This will log all results into the file collect_log. This will open a sub-shell and records all information through this session. The script ends when the forked shell exits. I hope this helps.
