pretty print compressed JSON file

The highly useful json.tool stops short of parsing compressed JSON files. In particular, if you use the json-smart*.jar to produce your json files, you are out of luck with json.tool. But you can use jsonlint like this to get a readable view of your json file :

[~] echo '{json:"obj"}' | python -mjson.tool
Expecting property name: line 1 column 2 (char 1)
[~] echo '{json:"obj"}' | jsonlint -p 2> /dev/null
{
  json: "obj"
}
