| is "pipe", meaning stream the output of the previous command as input to the next.

- means take arguments from stdin, in this case from the return value of the piped statement.

> is simple file redirection. Redirect the command's normal output (to stdout) to a file named by whatever follows this operator.

The fact that -> are run together is irrelevant. It is two separate operators.
