Cloudinary is an amazing image hosting service that offers both a highly functional free tier in addition to a paid enterprise grade image hosting and transformation service.
In this tutorial I demonstrate a few simple bash shell scripts to interface with Cloudinary.
This is a quick tutorial about setting up a simple shell script that runs periodically to update a DNS record on the internet with the IP address of your network. If you’ve ever wanted to have myhome.mydomain.com always updated with your home IP address, this is one way you can do it. There are paid and free services that offer this functionality, but I choose to use this method because it gives me ultimate flexibility over my domain.
This tutorial assumes you have your own Top Level Domain (TLD) and that you’ve configured it to use Digital Ocean as the authoritative DNS for it. Here, I’ll use “example.com” as the top level domain.
Log in to Digital Ocean and click on API from the top Menu. Click the Generate New Token button and give it a name. The name is not parsed, it’s just for your own reference. I like to give it something descriptive to my application. For this example, I’ll use MyDNS. Be sure to check the box next to Write so we can update the records using this API Key.
Once you have the API Key, save it somewhere for reference. It’s one of the 3 variables we’ll need to update in the update_do_dns.sh script.
The API Key will look something like this:fe3aeda96b7wer8wer1e6bb5erae528sdf3a6120dfrf7e492bwer6343fsdf
I put together a quick bash shell script to view system info at a glance. I know there are existing tools for this like inxi, but I wanted to put something together I can copypasta. This is specific to RHEL, Centos and Sci Linux but it can be easily adapted for other distros.
