JsonKeyCompare

A very simple program that compares two or more JSON files and reports any keys that are present in the first file but not in any of the other files.

Usage:

jsonkeycompare <main_file> <other_file_1> <other_file_2> ... [--fail] [--sort]

Options:

--fail
    Exit with non-zero status if any files are missing keys.

--sort
    Sort the output alphabetically.

Tip:

You can use wildcard expansion (at least on Linux) to compare multiple files easily:

jsonkeycompare main.json *.json
