It appears as if something odd is up there, the "rm out.txt" has been executed 
as "rm -f out.txt" so either there are aliases involved somewhere, in which case
there is a $ENV type script with unknown contents, or the script that is
being tested isn't the script shown.

In either case, whatever happened needs to be discovered and understood
before looking for other possible bugs.
