Today, I will show you how to get and display user details using a shell script. This work is based on a Python-based solution by David Green and located at bitbucket/nordapi.

In a blog post a month ago, I described how to use a terminal to display servers recommended by NordVPN, but the same result can be achieved by using public API service. It is not officially documented, so let’s play with it.

I have already described a simple way to manually configure Network Manager and automatically import NordVPN servers, so today, I will explain how to pretty print servers recommended by NordVPN using terminal instead of web-browser.

Delete Nextcloud bookmarks using API. Notice, data is paginated in this case, so this particular case is more interesting than regular add/remove operations.

I am currently playing with floccus to store bookmarks using Nextcloud, so I have created simple shell scripts to import Nextcloud bookmarks from Firefox using code from my earlier solution to open Firefox bookmarks from the OpenBox menu.

There is a bookmark manager for Nextcloud that can be used with the floccus browser extension to synchronize bookmarks using Chrome, Firefox, and Opera. I will show you how to perform API calls to automate the backup process.

Use the extensive API offered by the Restyaboard to backup and restore created boards.
