G'day AltGrendel,

"Both work, however, when I use the first I have one server that apparently has hidden characters that would cause the the line to split prematurely. I expect the problem is in the split() in the foreach, ..."

I don't think it's the foreach loops. I think it's occurring with "my @trace = ...". Here's my untested guess at what's happening.

In the first case, you're splitting on a single space 's' character ("my @trace = split("\s", ..."). [Update: see explanation below by ++AnomalousMonk.]

In the second case, with "my @trace = <EXE>;", you're effectively splitting on a newline ("\n") which is the default value for the input record separator, $/ (see perlvar: Variables related to filehandles).

Try changing that first line to: my @trace = split("\n", ...
