copying stdout and stderr to seperate files


i want to run a script that creates large quantaties sdtout and posts errors to sterr putting these into 2 seperare files, (eg stdout.txt and stderr.txt) (extentions only for conviniance!)

however i also want thease to do to stdout and std error on the screen.

i have been using "tee" to do this ie.
command | tee [filename]
but this doesnt do anything with stderr (which is more impiortant that stdout)

what would be the best way to do this?

command 2>&1 | tee filename

This will redirect standard error into stdout.
So the file will have both

redirect your stderr to stdout using
2>&1 like
Code:
echo "hi" 2>&1  | tee -a a.txt;
