Question Script passwd command by reading passwords from a file

I am attempting to create users by writing a perl script which opens and reads a file line by line. A typical line consists of logon|fullName|password. I am able to create the user account as expected. However, the passwd command does not set the password correctly since it requires the password to be re-entered. Here is the code that I am using:

sub createUser
my($logon, $fullName, $password)=@_;
my $useradd = `useradd -c "$fullName" $logon`;
my $setPasswd = `echo $password | /usr/bin/passwd --stdin $logon`;

Specificially, the set password part does not seem to work without my interaction.

This is how you can do it in bash without being prompted to do it again.

passwd --stdin < passwordfile username
passwd --stdin < pswdfile thomas
You would have to create a temporary file called pswdfile and the remove it.

Since you are writing this in perl you would have to make those lines into system calls.
