Could someone explain what's going on here?

my @trace = split("\s",(`traceroute -w 2 -q 1 -i dmfe0 $ip_address`)); my @trace_out = ""; foreach (@trace){ $_ =~ s/\n//; if ( $_ =~ /some|checks|here/ ){ @trace_out = (split /\s+/, $_ ); } }

and

open EXE, qq{/usr/sbin/traceroute -q 1 -w 2 -i dmfe0 $ip_address |}; my @trace = <EXE>; my @trace_out = ""; foreach (@trace){ $_ =~ s/\n//; if ( $_ =~ /some|checks|here/ ){ @trace_out = (split /\s+/, $_ ); } }
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, but since the open EXE works just fine I'm going with that anyway. Just curious.
