redirecting stdout and stderr in a script

Hi
Ive written a script that basically extracts tar files, copies files and
installs software.

I want to capture the output of stdout and stderr to a log file as well as
viewing it on screen.

Ive worked out that I can use any_command 2>&1 | tee log.file .

Is there anyway that I can do this once globally for the script or do I have
to set it at the end of every command?

Thanks in advance
Dan.
