Question

After I had typed a long command in the bash, i determined not to execute it for some reason.
But i just wanted to start a new line without clear the command. That command was still on the screen? Somebody help me?

#I typed as below:
$>find -name "filepattern" -exec grep "hello" {} \;

#I wanted as below without executing the 'find' command.
$>find -name "filepattern" -exec grep "hello" {} \;
$>

You can use ctrlc to ‘cancel’ a command you’ve typed.

My testing, on OS X:

bash-3.2$ find -name "filepattern" -exec grep "hello" {} \; <ctrl+c>
bash-3.2$ 

bash-3.2$ /bin/bash -version
/bin/bash -version
