Debugging notes:
BASIC called:  Print debugging aka tracing aka x-trace
-x prints commands and arguments as they executed
    means that instead of variables being displayed the values of those variables is displayed
    also trud for expansions wildcards are not displayed but what the expand to is displayed.
  add the -s option to the #!/bin/bash statement as in #!/bin/bash -x
  or inline use set -x to Set
     and set +x to stop...

-e = exit on error.
can be combined with other options at the shebang statement

-xe
