in thread -s test option returns differently in some cases

You won't believe it but...

print "# Command file is located at: $cmd_path\n" if (-e $cmd_path); # system("ls -l $cmd_path"); if (-s $cmd_path) {# $cmd_path) { print "Good to go"; } else { print "Failed: $!"; }

gives "Failed: No such file or directory"

print "# Command file is located at: $cmd_path\n" if (-e $cmd_path); system("ls -l $cmd_path"); if (-s $cmd_path) {# $cmd_path) { print "Good to go"; } else { print "Failed: $!"; }

gives "Good to go"

Same file, same code, same everything except that extra statement in between. An empty system(""); call does the same (works). Ideas?!
