exec $next_available_file_descriptor > &1;

In bash you can assign a new file number to stdout:
Code:
exec 3>&1
It's like the "dup2" system call.

But is there a way to assign an automatic file number?
Is there an analog of "dup"?

I can only think of scanning /dev/fd for the next available number

The bash source code is where I would look for this.
