Why `curl | bash` is a dangerous bad habit

Wed, 29 Apr 2026 09:42:21 +0000

Recently, I stumbled again upon an old bad habit from the Linux/DevOps/Cloud world: installing a tool with a command like:

curl -sSL https://example.com/install.sh | bash

Or worse:

curl -sSL https://example.com/install.sh | sudo bash

We have all seen it before.
We have probably all used it at some point.

And let’s be honest for a minute: in many official documentations, this is still presented as the “simple” way to install a tool.

Create a local Kubernetes cluster with Vagrant

Testing Kubernetes is quite easy thanks to solutions such as Minikube.

However, when you want to test cluster-specific features, such as load balancing or failover, it is not necessarily suitable anymore.

It is possible to build your Kubernetes infrastructure on servers, or by using managed services from a cloud provider (Kapsule at Scaleway, AKS at Azure, GKE at GCP or EKS at AWS for example).

Nevertheless, these solutions cost money. When you just want to test functionalities or self-training, it’s not necessarily appropriate.

I tested for you: Raspberry Pi imager

A few days ago, the Raspberry Pi foundation announced the release of a new utility to deploy its OS on its Raspberry.

Having 2 Raspberries to reinstall, I thought I would test it for you. A little overview.

User friendly installation

As I was talking about last week, one of the challenges of Linux is to make it more accessible to non-technical users.

This utility is particularly aimed at this type of user, since the installation is very simple compared to the existing alternatives.

All operating systems are bad!

I’ve been working in the IT world since I came of age, a little over 14 years now.

One of the only constant rules I’ve always found is that the OS you love is always better than all the others.

The gems I’ve heard around me

Among the phrases I can often hear, I could mention a few:

How do you want to develop under Windows?
A MacBook is a PC with a 1K apple on it.
Linux is like a Mac, but without the stability

I could go on like this for a long time.
