jsed: A JSON Editor
jsed is a small command-line utility to add, remove, and search for data in a JSON structure.
Not to be confused with any other jsed.

$ echo {} | jsed add object --path foo --value bar -r
{
"foo": "bar"

$ echo {} | jsed add object --path foo --value bar | jsed add array --path bar.baz --value a --value b --value c -r
{
"bar": {
"baz": [
"a",
"b",
"c"
]
},
"foo": "bar"
}
$ echo {} | jsed add object --path foo --value bar | jsed add array --path bar.baz --value a --value b --value c | jsed get --path bar.baz.1
b
$ echo {} | jsed add object --path service \
--key name --value redis_master \
--key address --value 127.0.0.1 \
