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

1. Press Ctrl-U to delete everything before the cursor. The deleted command will be stored into a buffer. Press Ctrl-Y to paste the deleted command.

   (Optional: Press End or Ctrl-E to jump to the end of the input first.)

2. Alternatively, press Ctrl-C to abort what you're typing.
