Output UNIX environment as JSON
This works for me:
python -c 'import json, os;print(json.dumps(dict(os.environ)))'It's pretty simple; the main complication is that os.environ is a dict-like object, but it is not actually a dict, so you have to convert it to a dict before you feed it to the json serializer.
Adding parentheses around the print statement lets it work in both Python 2 and 3, so it should work for the forseeable future on most *nix systems (especially since Python comes by default on any major distro).
