In my previous post, I wrote about using Eza on Fedora 41, which works well and it can be installed via dnf.

I’ve streamlined my blogging process using Hugo by automating tasks with the Fish Shell. I created a simple script that saves me a few minutes each time I write a new post. It automatically starts a new Hugo post and opens it in Helix editor, allowing me to write, save, and publish with ease.

As I continue to explore the world of Data Engineer, Linux, Fedora and other intersting topics, I often find small but interesting topics, that don’t deserve a full blog post, but I don’t want to let these discoveries to go away. In this section, I’ll be documenting and sharing short snippets of knowledge, tips and tricks that I’ve learned along the way. These posts will be bite-sized, easy to digest and hopefully, useful to others who may be on a similar journey. ...
