The real problem here is you are typing those "sensitive password or key" into termianl. Instead of type it directly, Use `read password` and `mysql -p$password` is the right way. Additionally, most programs can use environment variables directly, so you can even avoid showing them in the command line arguments. If you entered something in terminal directly, I won't call it sensitive.
