Cli for a document existing in memory or disk?

Is there a command line interface method to verify if a document is in memory or on disk? If that is not possible, a method that counts the number of documents in memory or on disk?
Thank you.

I’ve been able to find the % of documents that are resident using cbstats. How does one determine if a specific document is in memory or on disk?

I posed this question a month ago. Can someone help me?
Thank you.

This can be done from the command line with a combination of cbc hash and cbc stats with the “key” argument. The cbc utility is documented with libcouchbase and the stats possible are documented with Couchbase Server.
