[Linux trick] Nicely colored RPC output!

Hi all I made this bash alias to call ppcoind rpc inside a docker container without having ppcoind locally.
The cool thing is that it gives colored json output!

It has one dependency: jq (https://stedolan.github.io/jq/)

Add (and edit the connection details) this to your .bashrc:

function rpc_request {
    if [ $# -gt 3 ]
    then
        printf -v var "\"%s\", " "${@:4}"
        params=${var::-2}
    else
        params=""
    fi

    request="{\"jsonrpc\": \"1.0\", \"id\":\"curltest\", \"method\": \""$3"\", \"params\": ["$params"] }"
    curl --user $2 --data-binary "${request}" -H 'content-type: text/plain;' $1 | jq -C
}

alias rpc="rpc_request localhost:9902 user:password"

note that you can create multiple aliases for different rpc servers.

Usage example (multiple parameters are supported):
