Read JSON variable in Shell Script












2















How can I read a JSON variable in shell script ( to be noted "JSON variable " and not JSON File)?
I have tried something like,



temp={"name":"Sipdy","time":"17:09 1985","place":"CA"}

jq '.time' $temp


and also tried



temp={"name":"Sipdy","time":"17:09 1985","place":"CA"}

jq '.time' $temp


but both the above commands expect a JSON file name in place of "$temp".






json shell

          You need to provide the JSON text as jq's standard input:



          $ temp='{"name":"Sipdy","time":"17:09 1985","place":"CA"}'
          
$ echo $temp | jq .time                                   
          
"17:09 1985"
          
$ jq .time <<< $temp
          
"17:09 1985"


          (The second form is a here string.)
