The latest version of the complete perlfaq is at http://faq.perl.org . -------------------------------------------------------------------- 8.9: How do I ask the user for a password? (This question has nothing to do with the web. See a different FAQ for that.) There's an example of this in "crypt" in perlfunc). First, you put the terminal into "no echo" mode, then just read the password normally. You may do this with an old-style "ioctl()" function, POSIX terminal control (see POSIX or its documentation the Camel Book), or a call to the stty program, with varying degrees of portability. You can also do this for most systems using the "Term::ReadKey" module from CPAN, which is easier to use and in theory more portable. use Term::ReadKey; ReadMode('noecho'); $password = ReadLine(0); -------------------------------------------------------------------- The perlfaq-workers, a group of volunteers, maintain the perlfaq. They are not necessarily experts in every domain where Perl might show up, so please include as much information as possible and relevant in any corrections. The perlfaq-workers also don't have access to every operating system or platform, so please include relevant details for corrections to examples that do not work on particular platforms. Working code is greatly appreciated. If you'd like to help maintain the perlfaq, see the details in perlfaq.pod. |
