Hi All,

I want to echo debugging statements inside a function
the returns its value as an echo.  But I do not want
the debugging echo to be part of the return echo.  I want
the debugging echo to go to the screen instead.

#!/bin/bash
abc () {
    echo "I want this to go to the screen"
    echo "This goes to the return string"
}
echo "-->$(abc)<--"

If you run the above, you will notice everything
goes to the return variable.

Many thanks,
-T
