Redirect stderr and stdout to separate files in Bash?

I am able to redirect stdout and stderr to separate files using:

dir >> out 2>> error

or stderror and stdout together to a single file using:

dir >> consolidate 2>&1

How can I do this together (get out, error, consolidate files at a time)?

There's no need for any bashisms, as this can easily be done in standard sh:

{ { dir | tee -a out; } 2>&1 >&3 | tee -a error; } >> consolidate 3>&1

You can try something like: 

(command > >(tee out.txt) 2> >(tee error.txt >&2)) &> consol.txt

Test:

$ ls
f


$ ls g*
ls: cannot access g*: No such file or directory


$ (ls g f > >(tee out.txt) 2> >(tee error.txt >&2)) &> consol.txt


$ cat out.txt
f


$ cat error.txt
ls: cannot access g: No such file or directory


$ cat consol.txt
f
ls: cannot access g: No such file or directory
