Bash parse mode from status

[mherger]

Another option I'd recommend is jq (https://stedolan.github.io/jq/), a tool which allows you to query JSON results on the command line. It's available on many systems as a package, afaik:

curl -sX POST -H "Content-Type: application/json" -d '{"id":1,"method":"slim.request","params":[ "00:04:20:...", ["status","-",1] ]}' http://musicpi:9000/jsonrpc.js | jq ".result.mode"
"stop"

This would extract the "mode" element of the "result" within the response.

Try this:

curl -s -X POST -H "Content-Type: application/json" -d '{"id":1,"method":"slim.request","params":[ "aa:aa:bb:bb:cc:cc", ["'status'","-",1] ]}' http://localhost:9000/jsonrpc.js | awk -F\"mode\":\" '{print $2}' | awk -F\",\" '{print $1}'

Awk is one tool that can be used to parse formatted text. It may or may not be the best one for this purpose, but it's the one I'm most familiar with.

Hey,

I want to parse in bash with curl the status if an audio is playing or stopped to play another audio afterwards.
Read already "mode":"play" and "mode":"stop" with

curl -i -X POST -H "Content-Type: application/json" -d '{"id":1,"method":"slim.request","params":[ "aa:aa:bb:bb:cc:cc", ["'status'","-",1] ]}' http://localhost:9000/jsonrpc.js

but cant parse the mode tag to read the state and run another code.

Adding jq to the end of URL does not help me out

curl -i -X POST -H "Content-Type: application/json" -d '{"id":1,"method":"slim.request","params":[ "bb:bb:6c:cf:fc:b2", ["'status'","-",1,"tags"] ]}' http://localhost:9000/jsonrpc.js | jq '.'

Would be happy for advice and help.
