Automate getting a JSON URL and commit to a git repository?

Question

I need to read an existing URL of a JSON document, save it to a file, and commit that file to a git repo on a daily schedule. This seems easier than it's appearing so far, to me.

I'm assuming some sort of Cron job or scheduler, but I haven't been able to find a good solution.

Answer 1

The solution seems to be rather simple:

#!/bin/sh
set -e
cd /path/to/repository
curl -LOR http://$URL/file.json  # download the file
git add file.json
git commit -m "file.json at $(date +%Y-%m-%d)"

file.json is just a placeholder, put the real filename in your script. date +%Y-%m-%d generates the current date for commit message.

You can use wget instead of curl :

wget -O file.json http://$URL/file.json

Make the script executable and call it from cron:

0 9 * * * /path/to/the/script

This calls the script at 9:00 every day.
