Thank you Derek, I will give it a try.

I started looking in Perl, but could not find anything.

I am trying to automatically generate 100 accounts for a software, I
don't want to create them with the web interface, so having the password
on the history is not a problem (and I am asked to have the
password=username, so the quality of password is not a worry :)
