The set based paradigm of SQL lends itself very well to reporting and processing files, and is known by 7 million people.
SELECT extension, count(*) FROM files GROUP BY extension ORDER BY extension;
We built a tool, free for personal use, that does SQL at the command line
Unless the underlying model has all of that, I don't see how it competes with bash/ps
It should be doable but requires more than a filesystem relational model
Select * from processes order by priority
I mean I see the benefit of using Sql, had I mastered it, for files, but I'd be reluctant to sort and group reg keys or users or devices or processes or env vars differently from files in my shell language. You must have a "relational model" for the file system, do you have a way to (or plan to) generalize this to general structured data?
