Version: (using KDE KDE 3.5.5) Installed from: Ubuntu Packages OS: Linux when i enter a command from konsole with sudo in front and the & prefix at the end of the closet iget a prompt for the root's password.As i enter it the passwd is written on the screen .
Appending the '&' character to the end of a command causes it to run in the background. In this case sudo prints the "Password:" part of the prompt and goes into the background, and so when you type - you are in fact interacting directly with bash and not actually entering a password into sudo. For example, run "sudo xyz&" and when the "Password:" text is displayed, type in "ls" and press return - and you can see the output from running the ls command. To get back to the password prompt, type "fg" in the shell.
