Database drivers exist for a reason. Shelling out to a database cli interface is full of potential pitfalls that don’t exist in any language with a programmatic interface to the database. Dealing with query parameterization in bash sounds un-fun and that’s table stakes, security-wise.

Same with making web API calls. Error handling in particular is going to require a lot of boilerplate code that you would get mostly for free in languages like Python or Ruby or Go, especially if there’s an existing library that wraps the API you want to use in native language constructs.

I worked with dedupe products at a previous job. Media files generally deduplicate poorly.
