How do I ask the user for a password?

Current Perl documentation can be found at perldoc.perl.org.

Here is our local, out-dated (pre-5.6) version:

(This question has nothing to do with the web. See a different FAQ for that.)

There's an example of this in crypt). 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 the POSIX manpage, and Chapter 7 of the Camel), 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);

[marioroy]: I will make a mp3info script that takes the -p "%S\n" args and test qx. I'm on the road, so will come back.
[marioroy]: All because File::Find is not fun for LA.
[marioroy]: good night Discipulus.
[Discipulus]: perl dreams to you all
[marioroy]: LA my @music_times = qx(find \$HOME/Music/ Albums -type f -iname \'*.mp3\' -exec mp3info -p \"%S\\n\" {} \\;);
[marioroy]: Only 2 backslash \\n
