How can I suppress output only if the command succeeds?

I would like to simplify the output of a script by suppressing the output of secondary commands that are usually successful. However, using -q on them hides the output when they occasionally fail, so I have no way of understanding the error. Additionally, these commands log their output on stderr. Is there a way to suppress a command's output **only if it succeeds**? For example (but not limited to) something like this: mycommand | fingerscrossed If all goes well, fingerscrossed catches the output and discards it. Else it echoes it to the standard or error output (whatever).
