Perl Related question

Hi,

I am new to this forum so if this is not the right place to post this please redirect it. I have a perl script obtains passwords from STDIN and passes it to a java program(Utilities) as command line arguments, as shown

my $Utilities = "C:/jdk/bin/java -classpath $ENV{CLASSPATH} Utilities $oldpass $newpass";
system ($Utilities);

For security reasons I would like to pass the passwords as standard input to the java program instead of command line argruments.
I am really very new to perl and would really appreciate any input.

Thanks
Geraldine

I'm not a Perl-guy but decided to do some googling and found this:
