It's a shell question, not an OS question.  Your best bet is to use a
Bourne shell, in which case file redirection use the syntax "prog N>
file" where N is the file descriptor and defaults to 1.  The syntax &M
duplicates file descriptor M into an "lvalue", so that "prog N>&M"
sends both N and M to wherever N was at the time.  Note that it is a
duplication, not an identification, so that "prog 1> file 2>&1" send
both stdout and stderr to file, while "prog 2>&1 1>file" sends stdout
to file and stderr to stdout (this actually has semantics: stderr is
now buffered, where normally it is not).

I don't think any of the shells have syntax for sending different FDs
to different pipes; use the "y" program for that.  However, I don't
see a "y" program on Debian or an old Red Hat Linux.  If you need two
"consoles", you could use something like

prog 1> tmp1 2> tmp2 &

and

tail -f tmp1
tail -f tmp2

in the separate consoles.
