arrays - Loop through json using jq to get multiple value -

here volumes.json :

{ "volumes": [     {         "availabilityzone": "us-east-1a",         "tags": [             {                 "value": "vol-rescue-system",                 "key": "name"             }         ],         "volumeid": "vol-00112233",     },     {         "availabilityzone": "us-east-1a",         "tags": [             {                 "value": "vol-rescue-swap",                 "key": "name"             }         ],         "volumeid": "vol-00112234",     },     {         "availabilityzone": "us-east-1a",         "tags": [             {                 "value": "vol-rescue-storage",                 "key": "name"             }         ],         "volumeid": "vol-00112235",     } ] } 

i need both value of volumeid , tags.value used input invoke command. easy single value json array, not able extract multiple value , pass bash command.

i can single value using this:

cat volumes.json |jq -r '.volumes[].volumeid' |while read v; another_bash_command $v; done 

but not able multiple value cause wrong:

 cat volumes.json |jq -r '.volumes[].volumeid, .volumes[].tags[].value' |while read v w; another_bash_command $v $w; done 

as loop 6 times of outcome instead of 3.

and, how pass multiple json value in loop bash array can use value in better way ? volumeid-> $arr[0][0], tags.value-> $arr[0][1], availabilityzone-> $arr[0][2]...etc. have searched through , jq docs, , tried readarray, still not able find out solution :( given.

it seems me want output 2 values (volumeid , tags[].value) on same line?

if that's case, simple string concatenation should enough:

$ jq -r '.volumes[] | .volumeid + " " + .tags[].value' volumes.json vol-00112233 vol-rescue-system vol-00112234 vol-rescue-swap vol-00112235 vol-rescue-storage 

the above can used in pipeline while-read:

$ cat my_script jq -r '.volumes[] | .volumeid + " " + .tags[].value' volumes.json \ | while ifs= read -r volumeid tagvalue;   other_command "$volumeid" "$tagvalue" done 

you should note if there more 1 element in tags result reflect that. can avoided referring first element in tags: .tags[0].value
