I try to use read command to catch what user enters.
read -p "Please enter your name -> " -n 20 name
But I figured out that we can’t rectify what we have entered. How can I make the “BackSpace” remove and not add?
The easiest way is to use the
-eflag to read, which will make it use readline.You could also change your terminal settings (stty) so that backspace instead of delete is erase.
