Can you do what they suggest in Debugger Customization?

Edit: To be specific, you want to implement a .perldb file, with the afterinit subroutine that pushes commands to the @DB:typeahead array. You might want to try something like the following (untested):

#This is your .perldb file, it lives in ~/.perldb or ./.perldb, as per
+ [perldebug].
#Create a file of your debugger commands (one per line) and save it so
+mewhere. Put its location in the environment variable PERLDB_MYCOMMAN
+DFILE.

BEGIN {
    sub afterinit {
        if ( $ENV{PERLDB_MYCOMMANDFILE} && -e $ENV{PERLDB_MYCOMMANDFIL
+E}) {
            warn "Running commands from $ENV{PERLDB_MYCOMMANDFILE}";
            open my $cmdfile, "<", $ENV{PERLDB_MYCOMMANDFILE} or die "
+can't open $ENV{PERLDB_MYCOMMANDFILE}: $!";
            push @DB::typeahead, <$cmdfile>;
            close $cmdfile;
        }
    }
}
