Show HN: Dq – pipe-based CLI for querying CSV, JSON, Avro, and Parquet files

**Show HN: Dq – pipe-based CLI for querying CSV, JSON, Avro, and Parquet files**

I'm a data engineer and exploring a data file from the terminal has always felt more painful than it should be for me. My usual flow involved some combination of avro-tools, opening the file in Excel or sheets, writing a quick Python script, using DataFusion CLI, or loading it into a database just to run one query. It works, but it's friction -- and it adds up when you're just trying to understand what's in a file or track down a bug in a pipeline.A while ago I had this idea of a simple pipe-based CLI tool, like jq but for tabular data, that works across all these formats with a consistent syntax. I refined the idea over time into something I wanted to be genuinely simple and useful -- not a full query engine, just a sharp tool for exploration and debugging. I never got around to building it though...
