redirected output

Hello Everyone,
I have an option for users in my shell script to create log file. So if user saying �yes� on it, I'm redirecting all output to log file by doing this: > /output.log. However I would like the output being displayed on the screen at the same time. Is it possible? If yes, does anybody knows how to do that?
Many thanks in advance.

use the tee command. There is a switch -a that will append all output to your log file as well as send it to standard out (your screen). Example tee -a

See man tee

Thanks very much , Google. That works!
