Merge all of VCDB data (https://github.com/vz-risk/VCDB) into one big JSON file

vcdb-join.py

import os
import json
import sys

# initialization
directory = sys.argv[1]
dir_list = os.listdir(directory)
vcdb = []

for filename in dir_list:
    with open(os.path.join(directory, filename), 'r') as in_file:
        vcdb.append(json.load(in_file))

with open(sys.argv[2],'w') as out_file:
    json.dump(vcdb, out_file)
