C command-line password input

Question

I want to allow users to enter password using command-line interface. but I don\'t want to display this password on screen (or display \"****\").

How to do it in C?

Answer 1

For C/commandline/linux see:

man getch
man noecho

see the coment in getch about noecho. I've never tried this myself.

In bash if you use read -s it does not echo on the screen:

> read -s x
<type something><enter>
> echo $x
<whatever you typed>
