Every day, one of the first things I do on my computer is run an update/upgrade. That process normally consists of three commands, which are:
- sudo apt-get update
- sudo apt-get upgrade -y
- sudo snap refresh
That’s not too much to type. The only problem is that I have to wait for the previous command to stop before I can type the next. Or, I can combine them into one long command like this:
sudo apt-get update && sudo apt-get upgrade -y && sudo snap refresh
That combination means I don’t have to wait for one command to complete before typing the next.

Even so, that’s a long command to type every morning.
Fortunately, this is Linux, so there’s always a way to make things easier — and in this case, it’s via aliases.
Simply put, an alias allows you to configure a single word to serve as an alias for a command. So, instead of typing:
sudo apt-get update && sudo apt-get upgrade -y && sudo snap refresh
All I have to do is type:
I’m immediately prompted for my sudo password and all three commands will run (one after another), to take care of the update/upgrade/refresh process for me.

Let me show you how. It’s quite easy and can make your Linux-using life considerably more efficient.
How to create your first Linux alias
What you’ll need: The only thing you’ll need for this process is a running instance of Linux. It doesn’t matter what distribution you use because aliases are available to all of them, from the user-friendly Ubuntu all the way to the fiercely complicated Gentoo. I’ll demonstrate on my current go-to Linux distribution, Ubuntu Budgie.
The first thing to do is log in to your Linux desktop or server and open a terminal window.
The file that houses aliases is called .bashrc. The .bashrc file is a script that holds a number of commands and environmental settings that are executed when a user logs into their Linux account. Within that file, there’s a section that includes a number of pre-defined aliases (such as ll for the ls -alF command).

We’re going to create an alias for the upgrade process I outlined above. Keep in mind that the distribution you use will dictate the command you run (for example, dnf in place of apt for Fedora Linux).
Open the .bashrc file with the command:
Below, we’ll add our alias, which looks like this:
alias update="sudo apt-get update && sudo apt-get upgrade -y && sudo snap refresh"
The breakdown is simple:
The word alias informs bash that what follows is an alias. SHORTCUT is the word you want to use for the alias as a shortcut for the command that follows. COMMAND is the actual command you want to use for the alias, wrapped in single quotes.
Save and close the file.
Testing the alias
Don’t close the current terminal window. Instead, open a second terminal (or a new tab in the current window) and type the shortcut we used for the alias (in this case, update). The update command should run. If it does, congratulations, you’ve just created your first Linux alias.

Remember, however, that if you’re not using an Ubuntu-based distribution, the command you run for the alias will be different. And if your distribution doesn’t use Snap packages, you’ll want to either remove the Snap bit or replace it with the Flatpak refresh command.
