Thanks to all who replied,
It seems that there are a couple of ways to do this,
Ive listed the methods used by Karl Vogel

Two ways to do it just once:

   a. Have a smaller driver script call the script that's doing all the
       work, redirecting the output as you have above.

   b. Use a subshell in your script like so:

       #!/bin/sh
       # set the PATH, do your sanity checks, etc.
       ...

       # real work starts here
       (
           command ...

           if test something; then
               command ...
           else
               some other command ...
           fi

           ...

       ) 2>&1 | tee logfile

Thanks
For the help
Dan.

Subject: 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.
