Alien

Alien is a cool tool for anyone who's ever felt lost in the world of Linux packaging. If you're new to Linux, figuring out all the different package formats can be pretty confusing. But here's the thing: I actually find it kind of neat that each Linux distro has its own way of doing things. It’s like they’re built just for their specific needs!

What is Alien?

Recently, I stumbled upon Alien, and even though it's not brand new, it's super interesting. This handy tool was created by Joey Hess and is now kept up by Kyle Barry.

How Does It Work?

So, what exactly does Alien do? In short, it’s a free and open-source command-line app that converts between different Linux package formats. You might be wondering what those formats are—well, let me break it down:

• Base (LSB or LSB-compliant)


• DEB


• RPM


• SLP (Stampede)


• PKG (Solaris)


• TGZ (Slackware)
  

The best part? Alien lets you convert between DEB and RPM packages, which are two of the most popular formats out there!

Installing Packages with Alien

If that wasn’t enough, Alien can also install the converted packages for you! It even tries to change the installation scripts automatically to fit your system.

A Word of Caution

Now, while converting is great, installing those packages comes with some risk. Different Linux distros use different packaging systems and managers. So if something goes wrong during conversion, you could end up with a broken system—yikes!

When to Use Alien?

This tool is really meant for those rare moments when an app just isn’t available in your distro's format. Nowadays, there are tons of alternatives like Snap or Flatpak that might work instead.

The Installation Process

You can get started with Alien right from your Terminal by running sudo apt install alien. After that, you’re ready to convert and install files! For example, if you want to change an RPM file into a DEB file, just run sudo alien --to-deb .

Your Safety Net!

I know it doesn’t have a fancy GUI or guarantee results every time—but trust me when I say it's awesome that Alien exists! Sure, most apps today come with multiple installation options already available—but hey, having this tool in your pocket doesn't hurt!
