I need to read a line of input from <STDIN>
without outputting to screen. ie
like a su command.

try

system('stty -echo');
$response = <STDIN>;
system('stty echo');
print $response;

presuming you're on a unix system....

This is an easy problem to fix. Try this, if you are on a Win32 system.

print "enter some information\n";
$info = <STDIN>;
chomp($info);

That should do it. Say you enter "some information" into the program, then the variable $info will have the value "some information" and you can decide what to do with it.

Vikter,

does that stop the "some information" from being echoed on the command line as you type it though? Which I think was charlsey's aim.

Is there a way of doing this on windows?
