Here is my structure:
I am trying to print some values in a JSON file. Here is the service-data.json:
{"service_name": "nphies-support.service","description": "nphies-support-service Spring Boot Application","user": "aceusr","working_directory": "/home/aceusr/deployment/nphies/nphies-support","java_home": "/usr/lib/jvm/jdk-21.0.1","jar_file": "nphies-support-service.jar"}I am reading this JSON in a bash script using jq:
#!/bin/bashecho "$0 script starting"# test if the jq is installedtest_json=$(echo "{ }" | jq)if [ "$test_json" != "{}" ]; then echo "jq not installed" exit 1fi#read json into variable jsonjson=$(cat service-data.json)#converting json objects to bash variabledeclare $(echo $json | jq -r 'to_entries | .[] | "export \(.key)=\(.value)"')echo "service_name = $service_name"echo "description = $description"echo "user = $user"echo "working_directory = $working_directory"echo "java_home = $java_home"echo "jar_file = $jar_file"#use the -r option to output the result as raw text, without quotes. description1=$(echo $json | jq -r '.description')echo "description1 = $description1"exit 0 This JSON is an object so I am using declare function to convert JSON into bash script variables.
For description it is only printing nphies-support-service instead of nphies-support-service Spring Boot Application. Looks like it is breaking on first space.
But when I read the same field using the syntax name=$(echo $json | jq -r '.description') it prints the whole text.
Why is it not printing the whole text in iteration? What do I do so it prints whole text for description variable?
