I am writing a script that uses the aliases of the current ksh shell and processes them. I am running into an issue where any execution (system, ``, open piping) of the "alias" command creates a new shell instance and does not gather my current aliases. I have tried a variety of approaches so far from the simple ways:

my $alias_str = `alias`;
my $alias_str_2 = `. alias`;
my $res = qx(alias);
open (PIPE, "alias |");

To even complex methods:

system "echo \"alias > aliases.tmp\" > get_aliases.ksh";
chmod (0777, 'get_aliases.ksh');
system '. get_aliases.ksh';
open (ALIASES, "aliases.tmp");
foreach my $line (<ALIASES>){
  print "alias line $line\n";
}

Nothing appears to be working because perl or ksh creates a new shell instance preventing gathering of the current shell's aliases.

Anyone have any ideas on how to pull the ksh aliases into perl? Thanks.
