    In bash, how do I do 
    echo "Hello World!"
    without the ! being interpreted as having a command history meaning, which is what I assume is happening here...
    # echo "hello world!"
bash: !": event not found

    ... ta

    echo 'Hello world!'

    If you use single quotes the special character (in this case '!') will not be interpreted.

    Another method is to escape the exclamation mark: 
    echo Hello world \!

    Again this will prevent the shell from interpreting the special character.
