Top Forums Shell Programming and Scripting Building JSON command with bash script Post 303039757 by psysc0rpi0n on Monday 14th of October 2019 06:00:13 PM

Hello...

I've started to try something new for my script.
I'm trying to iterate over a JSON object, search for a specific value in all keys present in that object and finally, add those values.
Knowing that a specific key value can be accessed by

Code:
echo "$json_obj" | jq '.[0] .key'

I tried to use a variable to iterate through all keys and print their values

Code:
json_obj=(bitcoin-cli listunspent)
for i in "${#json_obj}";
do
echo "$json_obj" | jq '.[$i] .address'

But I get the following error which I can't fix.

Quote:
jq: error: i/0 is not defined at <top-level>, line 1:
.[$i] .address
jq: 1 compile error
I think this means that 'jq' cannot "expand" the $i variable so it returns that error, but I have no idea how to fix this!

Any help?

Edited;
I even tried this, but couldn't make it work either
