Hi, I am developing a program that sets passwd for any user but i dont =
want the operator sets the passwd. I want to give it as a result of a =
function
[victor@mail victor]$ perl passwd.pl victor1
#!/usr/bin/perl
$usuario=3D$ARGV[0];
$passwd=3D"PASSWDGENERATEBYOTHERFUNCTION"
`sudo /usr/sbin/useradd -c $usuario -s /sbin/nologin $usuario`;
`sudo /usr/bin/passwd $usuario`;
I could add the user, but in the set passwd line.
When I use this script always I have a prompt of password assigment that =
I dont want. Could you give me some light of what can I do?
Thanks in advance,
Victor

The classic answer to this is to use the Expect module, because passwd(1)
historically has read only from /dev/tty.
However, if you're on Linux, passwd(1) has a --stdin option that lets you
supply the password via standard input. So you could write something like
(untested):
system "echo \Q$passwd\E | sudo /usr/bin/passwd --stdin \Q$usario\E";
