Getting user input from STDIN

s_gaurav1091 has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I have a perl script wherein I want to get the username/password for logging to a particular application.

print "\nlogin: ";
$username = <STDIN>;
chomp($username);

print "Password: ";
$password = <STDIN>;
chomp($password);

Bu this will show the password on the console. I don't want the password to be displayed when the user types in. I know we have a perl module Term::ReadLine through which we can do this. But I don't want to use this perl module. Please suggest. Thanks in advance

Term::ReadKey? Unless I state otherwise, all my code runs with strict and warnings	[reply]

Can you explain why you would not like to use Term::ReadLine? It is a core module since Perl 5.04. To me it looks the same as saying, "I want to drop the end-of-line character but I do not want to use `chop` or `chomp` or `substr>` and regexes are evil too."

There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James	[reply] [d/l] [select]

crypt has an example which uses `stty` command: `$pwd = (getpwuid($<))[1]; system "stty -echo"; print "Password: "; chomp($word = <STDIN>); print "\n"; system "stty echo"; if (crypt($word, $pwd) ne $pwd) { die "Sorry...\n"; } else { print "ok\n"; }` [download] However, this trick will only work on Unix-like systems.
