Problem with simple Formatted Input example.

[Venkat Akkineni via Digitalmars-d-learn]

This simple program seems to just hang. I am probably missing 
something. Any help is appreciated. I am using Linux with DMD. 
Program compiles fine, but when enter a string & press enter, the 
programs seems to wait forever without returning.

import std.stdio;

void main()
{
        
        string firstName;
        readf("    %s\n", &firstName);
        writeln(firstName);
        
}


Thankyou
Venkat
