Output JSON from Bash script

Question

So I have a bash script which outputs details on servers. The problem is that I need the output to be JSON. What is the best way to go about this?

Answer 1

data=$(echo  " BUILD_NUMBER : ${BUILD_NUMBER} , BUILD_ID : ${BUILD_ID} , JOB_NAME : ${JOB_NAME} " | sed 's/ /"/g')

output => data="BUILD_NUMBER":"29","BUILD_ID":"29","JOB_NAME":"OSM_LOG_ANA"
