|Is there a tool you'd recommend to diff tabular data / TSV files?|
Every day I have a snapshot of a database stored as TSV. Given two days of snapshots and that every item in the TSV has a unique ID, I'd like to get a list of which lines are new, changed, unchanged, and deleted between the two days. These lists will then be used to update an external service with an awkward database-like API.
