csvdiff --style=[summary pretty] a.csv b.csv
csvdiff allows you to compare the semantic contents of two CSV files, ignoring things like row and column ordering in order to get to what's actually changed. This is useful if you're comparing the output of an automatic system from one day to the next, so that you can look at just what's changed.
