in reply to Password (pseudo)casual

Hello cisco88, and welcome to the Monastery!

In addition to the excellent points made by Corion...

It’s always a good idea to:

use strict; use warnings;

in any Perl script. For one-liners, you can do:

perl -Mstrict -we ...

to get the same benefit. In this case, warnings would have given you messages of the form:

Use of uninitialized value in print...

which arise because the expression rand($len) % $len + 3 sometimes generates array indexes beyond the end of the @lett array.

Get in the habit of always using strict and warnings now, and you will save yourself a lot of time and grief in the future!

Hope that helps,
