jq: Change multiple values

Here is a method which uses + object addition to update multiple members.

. + {two:"newtwo", three:"newthree"}

Sample Run (assumes data in data.json)

$ jq -M '. + {two:"newtwo", three:"newthree"}' data.json
{
  "one": {
    "val": 1
  },
  "two": "newtwo",
  "three": "newthree",
  "four": "val"
}

Try it online at jqplay.org

Simply change the comma to a pipe character and you’re done:

.two="newval" | .three="newval"

"," is for concatenating streams: A,B will emit A followed by B.
