How to modify a key's value in a JSON file from command line

Question

Is it possible to change the value of a key in a JSON file from command line?

e.g., in package.json:

Change

{     ...     ...     "something": "something",     "name": "idan"      ... } 

To

{     ...     ...     "something": "something",     "name": "adar"      ... } 

Answer 1

One way to achieve it is by using the "json" npm package, e.g.:

json -I -f package.json -e "this.name='adar'" 

Another way is by using the jq CLI, e.g.:

mv package.json temp.json jq -r '.name |= "adar"' temp.json > package.json rm temp.json
