Modify the command above to find all “regular” files under /tmp that are owned by user oliver. and whose modification time is greater than 120 minutes ago and have find prompt you interactively whether or not to remove each one.

$find /tmp -user oliver -mmin +120 -type f -ok rm {} \;

Note:
The standard error is not redirected in this solution because that would prevent questions being asked by -ok from being displayed.
