Use github actions to concat json files - json

Question

I have a directory containing json files, and i want to use github actions to create a new file in the repository, that contains an array of all those json files.
for example, the directory <my-repo>/configurations contain the files a.json, b.json, I want to create a new file called configs.json contains [<a.json content>,<b.json content>].
The creation must be done dynamically.
Any suggestions?

solution for config files sitting under \configs directory:
name: build unified config file
on: [push]
jobs:
build_file:
name: build unified config file
runs-on: ubuntu-latest
steps:
- name: Check out the repo
uses: actions/checkout#v2
- name: setup python
uses: actions/setup-python#v2
with:
python-version: 3.8
- name: Run script
uses: jannekem/run-python-script-action#v1
with:
script: |
import os, json, shutil
with open("unified.json", "r+") as t:
t.truncate(0)
t.write('[')
for filename in os.scandir('configs'):
print(filename)
with open(filename, "r") as f:
content = f.read()
t.write(content)
t.write(',')
t.write(']')
barak = open("unified.json", "r+")
contentb = barak.read()
print(contentb)
- name: push file to main
uses: EndBug/add-and-commit#v9
with:
add: 'unified.json'
committer_name: Committer Name
committer_email: mail#example.com
default_author: github_actor
message: 'Update unified config file'
push: true
