I have this perl script...

==============CODE

#! usr/local/bin/perl5 -w

print '==============================', "\n";

open(LOG, ">>perl.out") or die;
        while(<STDIN>)
        {
                print LOG '===============================', "\n";
                print LOG @_, "\n\n";
                print LOG '==============================', "\n";
        }
close LOG;

# eof

==============END CODE

I have this receipt

# ------------------------------------------------------------

        * HB ?? ? "$HOME/vmail/perl/perl test.pl"
