## 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:
```shell
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:
```shell
jsonkeycompare main.json *.json
```
