open() and pipes quiz
What is the difference between these two lines (on Linux with Perl 5.8.x or 5.6.x). More precisely why does only first open die?
open(FH, '/doesnt/exist 2>&1 |') or die "Cannot pipe: $!";
open(FH, '/doesnt/exist\\ 2>&1 |') or die "Cannot pipe: $!";
Hint if you have no idea: try to remove 2>&1 from command line.
