Re^2: IPC::Open3 misbehaving when STDOUT is not FD #1

Portable?

use IPC::Open3;

use File::Spec;
my $devnull = File::Spec->devnull;


# Hide undesired output.
open(STDOUT, '>', $devnull);
open(STDERR, '>', $devnull);

# Associate STDOUT and STDERR with
# descriptors other than 1 and 2.
open(local *STDOUT, '>', $devnull);
open(local *STDERR, '>', $devnull);

open3(

`$^X` isn't properly converted to a shell literal. (i.e. Won't work if there's a space in `$^X`.) Fix: `open3( undef, local *PIPE, undef, $^X, q!-le print 111;print STDERR 222!, );` [download]	[reply] [d/l] [select]
