I know that entering passwords on the command line is a bad idea, because all someone would need to do is execute a ps -ef command to see your password. So I am wondering how could I pass as password to my perl script from a sh wrapper. Here is what I think will work ... 
bash-2.03$ cat test.sh 
#!/bin/sh
echo "Enter Password:"
stty -echo
read PASSWD
stty echo
export PASSWD
test.pl

bash-2.03$ cat test.pl
#!/usr/local/bin/perl -w
my $passwd = shift || $ENV{'PASSWD'};
while(1) {
        print "blah balh\n";
        sleep 1;
}

... this should be secure right?
