Right, so this is one solution, using tee, and some trickery:

This is my testing shell command will print foo on stdout and bar on
(printf "foo\n"; printf "bar\n" >&2) 

Using tee to get stdout in a file:
(printf "foo\n"; printf "bar\n" >&2) | tee stdout.txt

Using tee to get stderr in a file: 
(printf "foo\n"; printf "bar\n" >&2) 3>&1 1>&2 2>&3 | tee stderr.txt
