How to save the output to a log file without wiping the previous contents


Can someone tell me how to save the output to a log file without wiping the previous contents?
For example, I run a program called "luck" and it outputs a sentence like "good luck".
Then "./luck -> logfile" will save the output content to logfile.
But when I run another program called "hello" and it outputs a sentence like " Hello world".
Then "./hello-> logfile" will save the output content to logfile and wipe the previous contents.
Is is possible to keep both sentences in the logfile? Just like
good luck
Hello world

And, to make it completely clear, the syntax does not include a dash ('-'). Your example, modified for appending, would look like:
Code:
./hello >> logfile
--- rod.
