Bitcoin error parsing json

Question

 I have written a bash script to simulate the transactions between the nodes. The code is as follows:

#!/bin/bash

MAX_NODES=2

MY_PATH=/home/ubuntu/test

CLIENT=/usr/local/bin/bitcoin-cli

declare -a addr

function fcomp() {

        /usr/bin/awk -v n1=$1 -v n2=$2 'BEGIN{ if (n1>n2) exit 0; exit 1}'

}

json="'{"

#get addresses to send

for ((i = 1; i <= MAX_NODES; i++));

do

    addr[$i-1]="$($CLIENT -regtest -rpcport=$((16500 + $i)) -datadir=$MY_PATH/$i/ getnewaddress myaccount)"

    if [ "$i" -lt "$MAX_NODES" ]

    then

        json="$json\"${addr[$i-1]}\":0.00001, "

    else

        json="$json\"${addr[$i-1]}\":0.00001"

    fi

done

json="$json}'"

echo $json

#loop to send money to other nodes

for ((i = 1; i <= MAX_NODES; i++));

do

        balance=`$CLIENT -regtest -rpcport=$((16500 + $i)) -datadir=$MY_PATH/$i/ getbalance`

        if fcomp $balance 0.002; then

                $CLIENT -regtest -rpcport=$((16500 + $i)) -datadir=$MY_PATH/$i sendmany myaccount $json

    fi

done

echo json output:

'{"mj2FrDhEomSzyQtRoGY78oVRPcQs5L5o95":0.00001, "mkxnkT3kx9dsFS8V3qYydpL1o5F5MfwCvM":0.00001}'

I get the following error:

error: Error parsing JSON:'{"mj2FrDhEomSzyQtRoGY78oVRPcQs5L5o95":0.00001,

Make these changes in your code:

json="'{" to json="{" , json="$json}'" to "json="$json}" and $CLIENT -regtest -rpcport=$((16500 + $i)) -datadir=$MY_PATH/$i sendmany myaccount $json to $CLIENT -regtest -rpcport=$((16500 + $i)) -datadir=$MY_PATH/$i sendmany myaccount "$json"

Apparently, json was not being passed to bitcoin-cli. After making these changes, your error will be gone.
