Hi:

Your code redirects stderr for the function to set.log2, so that's where all the trace output will be found. If the calling script is only reading stdout (from a pipe or coprocesses or fifo), you don't need that redirection.

Quote:
-x
The shell shall write to standard error a trace for each command after it expands the command and before it executes it. It is unspecified whether the command that turns tracing off is traced.
-- Shell Command Language

Regards,
Alister
