How to get a readable format of curl with a transaction? Using curl https://blockchain.info/unspen?active=... with a valid ID I expect an output (according to my book) in a readable JSON format. 

Instead I get: 

bitcoin@raspberrypi ~ $ curl https://blockchain.info/unspent?active=1Cdid9KFAaatwczBwBttQcwXYCpvK8h7FK

This was just a problem of the terminal I used on a mac. 

Adding | python -m json.tool to the command does the trick, as described here. 

Output now is: 

bitcoin@raspberrypi ~ $ curl https://blockchain.info/unspent?active=1Cdid9KFAaatwczBwBttQcwXYCpvK8h7FK | python -m json.tool
