You can use pt-query-digest to analyze the general query log by passing the argument --type genlog. Since general logs do not report query times, only the count aggregate is shown:
shell> sudo pt-query-digest --type genlog /var/lib/mysql/db1.log > general_query_digest
The output will be something like this:
