In bash, how does one clear the current input?

Question

Suppose in bash you start writing a command like:

$ rm -rf /foo/bar/really/long/path/here

and then realize you don\'t want to execute this

Answer 1

Pressing Esc plus Backspace in bash will clear everything up to the cursor's position.

(In Cygwin, this will clear the input up to the next word. Words are separated by spaces, underscores, ...)
