[SOLVED] Store value of JSON key in Bash variable

Issue

I have a JSON where I am storing it in a variable in my Bash script like this:

RAW_JSON="{"secretKey": "ADFGHJKGBNJK"}"

I wanted to store the value of secretKey in another variable called secretValue. How can I do that?

Solution

To preserve double quotation (") marks around the key and value, the syntax is:

$ RAW_JSON='{"secretKey": "ADFGHJKGBNJK"}'
$ echo "$RAW_JSON"
{"secretKey": "ADFGHJKGBNJK"}

Then jq can be used to return the value:

$ secretValue=$(echo "$RAW_JSON" | jq -r .secretKey)
$ echo "$secretValue"
ADFGHJKGBNJK

The -r parameter removes the quotes from the result.
