In a moment of brilliance, I executed the command
source ~/.bash_history. Fortunately, most of the commands are using
vim to edit some file, but there are some scary commands in my history - moving and removing files with relative paths.
Fortunately right now it's stuck in a
vim session, however if I suspend or quit it, it's on to the next one. The history file is 1000 lines long.
How can I cancel this command, short of rebooting the machine?
