The problem here I think is because the pipe-open spawns a shell which fails
later on. Try this code:
[CODE]
#!/usr/bin/perl
use strict;
use warnings;
open my $search, "nonexistent-script.pl '(cn=peter*)'|" or die("error:
$!\n");
print "Foo\n";
if (!close($search))
{
die "Close failed - $!";
}
[/CODE]
Here the close fails.
