Guess i tried that with:
Code:
    CMD="dd if=$SOURCE of=$TARGET bs=$DD_BS "
    $CMD &  > $TUI_TEMP_FILE > 2&>1

But doesnt work -- keep getting all info on each loop to stout, but not to the file

trace-cmd-stack

TRACE-CMD-STACK(1)														TRACE-CMD-STACK(1)

NAME

       trace-cmd-stack - read, enable or disable Ftrace Linux kernel stack tracing.

SYNOPSIS

       trace-cmd stack

DESCRIPTION

       The trace-cmd(1) stack enables the Ftrace stack tracer within the kernel. The stack tracer enables the function tracer and at each function
       call within the kernel, the stack is checked. When a new maximum usage stack is discovered, it is recorded.

       When no option is used, the current stack is displayed.

       To enable the stack tracer, use the option --start, and to disable the stack tracer, use the option --stop. The output will be the maximum
       stack found since the start was enabled.

       Use --reset to reset the stack counter to zero.

SEE ALSO

       trace-cmd(1), trace-cmd-record(1), trace-cmd-report(1), trace-cmd-start(1), trace-cmd-extract(1), trace-cmd-reset(1), trace-cmd-split(1),
       trace-cmd-list(1), trace-cmd-listen(1)
