Store output diskspace df -h JSON

Question

I am attempting to gather basic disk space information from a server using a bash script, and store the output in JSON format. I am looking to record the available & use

Answer 1

Alternative Oneliner

$ df -hP | awk 'BEGIN {printf"{\"discarray\":["}{if($1=="Filesystem")next;if(a)printf",";printf"{\"mount\":\""$6"\",\"size\":\""$2"\",\"used\":\""$3"\",\"avail\":\""$4"\",\"use%\":\""$5"\"}";a++;}END{print"]}";}'

{
   "discarray":[
      {
         "mount":"/",
         "size":"3.9G",
         "used":"2.2G",
         "avail":"1.5G",
         "use%":"56%"
      },
      {
         "mount":"/dev",
         "size":"24G",
         "used":"0",
         "avail":"24G",
         "use%":"0%"
      }
   ]
}
