Clear password entry field in the shell UNIX
This is just a quick tip for those of you (like me) who constantly mis-type their password when telneting, and don't like to wait for the 'username: ' prompt to come back around. When you realize that you mistyped it, just hit Control-U, and it clears out the buffer! This works for telnet, ssh, and ftp, and it works on most UNIX systems.

^U is (by default) the 'kill' command, which will wipe everything on the current line. To see what other key commands exist by default, type:
stty -e

(not all will work in every shell, though)

Just use backspace

Why not just backspace and retype the password?

because sometimes the backspace key sends the wrong control character and instead of erasing what you just typed, it actually adds more characters to your password. Ctrl-U is the only reliable way I've ever found to erase your password in telnet, ftp, etc.

Oh, and don't use telnet or ftp. Use SSH. :)
