Lets say you are working on a known issue and you need to document the commands and their result.
You may use script command to capture various commands and its output.
How to use script
$script FILE-NAME
This command will open new shell. Now what ever command you issue,along with its output will be logged into FILE-NAME. Once you are done,press "CTRL-D" and you are out of screen command.
Although this command is very simple but it helps to document things.
