well, there it is then.. its not a 'child' its a peer..

Flexvault is mistaken. It's a child, and it does inherit environment variables. Here are a couple of linux scripts that demonstrate this. First, /tmp/myenv just prints any environment variables that have 'MY' in the name:

#!/usr/bin/perl
print "$_=>$ENV{$_}\n" for grep /MY/, sort keys %ENV;

Then the main script, which 'opens' myenv:

#!/usr/bin/perl

$ENV{MYA} = 'a';
$ENV{MYB} = 'b';
$ENV{C}   = 'c';
open(CMD, "/tmp/myenv 2>&1 |") or die "open: $!\n";
while (<CMD>) {
    chomp;
    print "got: <$_>\n";
}
[download]

Running this gives:

got: <MYA=>a>
got: <MYB=>b>
[download]
