How To: Install Proprietary Drivers In Ubuntu

Today is going to be a very quick and easy article, where we learn how to install proprietary drivers in Ubuntu – in the terminal, of course. It’s easy enough for a new user, as it’s just a single command. It’s also not all that well known and not documented in the man pages or anything, so I might as well cover it here.

There are all sorts of reasons why you might want to install proprietary drivers in Ubuntu. Some of your hardware may not work at all until you do. Some of your hardware will only have partial functionality until you do install the proprietary drivers.

Of course, if everything is working just fine, you might not even need to worry about the proprietary drivers in Ubuntu. If everything is fine, there’s no reason to worry too much. You know what they say, “If it ain’t broke, don’t fix it.” 

Of course, a subset of you will say, “If it ain’t broke, tweak it!”

Anyhow, this article only applies to Ubuntu and official Ubuntu flavors. It likely also applies to Ubuntu derivatives. A quick check seems to indicate that Mint is one of those derivatives that support this command. We’ll only cover it from the Ubuntu-specific direction. If it also works for you, that’s a benefit. If it doesn’t work for your distro, the maintainers likely took it out for a reason.

So then, let’s get to work installing proprietary drivers on Ubuntu…

How To Install Proprietary Drivers In Ubuntu:

As mentioned above, we’ll be doing this in the terminal. So, you’re going to need an open terminal for this exercise. You can just press CTRL + ALT + T and your default terminal should open.

With the terminal now open, we need to ensure you have the “Restricted” repository enabled. As you already have a terminal open, we might as well do that while in the terminal. So, type the following command:

Now, you need to update your database of software that’s available and we might as well make sure all other software is up to date. You do that with this command:

There you go. You’re now ready to install proprietary drivers in Ubuntu. So, while it’s a single command, it may require some preparation for some users. If you’ve run the above commands, we should be on the same page. So, with that, you just run the following command:

If there are any prompts, just go ahead and press the Y button. Everything should go smoothly and you may need to reboot after installing the proprietary drivers. When you’ve done that, you should be using the newly installed drivers instead of the open-source (or no) drivers. 

That’s all there is to it…

Closure:

There you have it! You have another article. I know I told you that it was just a single command and then shared more than one command, but it is just one command so long as you’ve got the Restricted repository enabled already (and I think most of us do). Either way, there’s a quick and easy way to install proprietary drivers in Ubuntu, in the terminal even. ‘Snot all that difficult after all!

How To: Show File Sizes When Listing Files In A Directory

Today we’re going to have an easy article that shows you how to show file sizes when listing files in a directory. It’s a simple set of commands and easy enough for a newbie to learn. Though the title is unwieldy, read on to learn how to show file sizes when listing files in a directory…

We’ll be using the ‘ls’ command for this exercise. Like normal, I’ll go ahead and suggest you read this page about why you shouldn’t parse the output from the ‘ls’ command. There are better ways and that link will explain it, and what you should consider, far better than I can.

Anyhow, the ‘ls’ command defines itself as:

ls – list directory contents

Of course, regular readers will recognize the ls command as we’ve used it numerous times before. Even though you shouldn’t parse the output from the command doesn’t mean it’s not still useful for a variety of other tasks.

Today, we’ll be exploring one of those tasks. We’re going to show you how to show file sizes when listing files in a directory – specifically with the ls command. Don’t worry, you won’t need to install anything. If you’re using any desktop Linux distro, the ls command is certainly available to you by default.

For the record, you should probably view the ls man page (run man ls in the terminal) to learn more about the command. It’s still a useful command – and I do sometimes parse the output from the command, but only when nobody is looking and when the output isn’t all that vital. I use grep with the ls command almost every day! Shh!!!

Show File Sizes When Listing Files In A Directory:

(That’s an unwieldy title!)

Anyhow, it’s the ls command. That’s a terminal-based command. So, of course, you’re going to need an open terminal (like so many of these articles). Press CTRL + ALT + T and your default terminal should open. Tada!

With your terminal now open, we can just use your home folder. To run the basic ls command, it’s just that:

Now, to show file sizes when listing files in a directory, you’d start with the -s flag:

You may find the output from that command is relatively useless without doing a bit of math to go along with it. Fortunately, you can tell the command to show the file size in a ‘human-readable format’. To do that, you’d run this command with the -h flag:

Now, if you wanted to show all the files, including the hidden files in that directory, you’d just add the -a flag. The command would look like this:

And if I was a Linux newbie, that’s the command I’d commit to memory. It doesn’t make a mess. The output is still plenty clear. It’s easy to understand. It’s easy to remember and turn into a habit. This way, when you ran the ls command, you just default to using -ash flags.

If you don’t want columns (and some do not), and you want more information such as file permissions or ownership values, you can just add an -lflag to the above. That’d look like:

So, it’s up to you…

You can remember ‘ash’ or you can remember ‘lash’. You can also not remember either and ignore the flags completely, but I find developing a habit is a good way to remember things. It’s your device, you do what you want!

Closure:

There you have it! You have another article. This one was simple enough and I hope you found it useful. If you’re new and running the ls command is new to you, it’s worth learning some additional flags and gathering more information at a glance. That’s why there’s this relatively simple article that shows you how to show file sizes when listing files in a directory.

Get Some System Information With Archey

Today’s article will be a fun one, where we figure out how to get some system information with Archey. It’s a mostly unnecessary article and Archey is definitely replicating work done elsewhere, but it’ll be fun!

Well, I think it’ll be fun…

I suppose you can decide that for yourself as you read the article. If you want to get some system information with Archey, read on (and maybe have fun)!

As regular readers might know, I’ve covered a variety of *fetch articles.

How To: Display System Information With screenFetch
Screenfetch vs. Neofetch, You Decide!
Show RAM Information With Ramfetch
Get Some Prettified CPU Information in Your Terminal With ‘CPUFETCH’

In fact, the ‘Screenfetch vs. Neofetch’ article is oddly one of the most searched articles on the site, at least from Google’s traffic.

Anyhow, Archey is like those (but written in Python, if that matters). If I understand correctly, it was Archey4 – a maintained fork of Archey. The original Archey project ceased development and now this project is just called Archey as it is no longer a fork but is the actual project.

I think I’m understanding that properly. If I’m not, hopefully, someone chimes in and lets me know the full story. Often my articles are visited by project leaders, so maybe that’ll happen in this instance and someone will set the story straight.

Either way, it doesn’t matter much – but it does explain why I’m simply referring to the project as ‘Archey’. If you check the man page, you’ll learn that Archey describes itself like:

A simple system information tool written in Python

Got it? Good! Let’s get started getting some system information with Archey!

Let’s Get System Information With Archey:

So, the first thing you’re going to need is a copy of Archey. That’s easily accomplished if you want .deb or .rpm. There are some odds that you’ll find it’s already in your repositories (like Arch or BSD). You can also use “pip” (Python packages from PyPI) to install Archey. There’s even a ‘homebrew’ version for Mac users.

Otherwise, if none of those will work for you, you might find you need the source code to build and install Archey.

This link should take you to the current release:

https://github.com/HorlogeSkynet/archey4/releases/latest

From there you can install Archey. Due to the huge variety of installation methods, I’m just going to tell you to follow the directions to install Archey. If you can’t get it installed, you can always ask for help and someone will hopefully get you sorted.

Once you have Archy installed, you can start getting system information with Archey. You just run the archey command and it’ll spit out something like this:

Achey displays system information.
I don’t think you’ll need me to explain. The screenshot should be adequate.

As you can see, Archey’s output is fairly normal. It likely reminds you of things we’ve already covered in earlier articles. That’s okay – it should remind you of things like Screenfetch and Neofetch.

Just like some of the other previously covered *fetch applications, you can take a screenshot automatically. After all, the goal of these applications is to give you some information that si easily captured as a screenshot so that you can show it off to your forum buddies.

However, possibly because I have Flameshot installed (which seems to have taken over the ‘screenshot’ command that Archey uses), I am unable to actually verify the screenshot bit. I dutifully took the screenshot with Shutter. But, the -s flag should work for other people. I tried a few times with Archey but got conflicting errors. Someone smarter than I probably have this sorted out.

I’m not going to go uninstalling stuff just to demonstrate it. If it doesn’t work for you, file a bug at the above-linked GitHub site. Also, you have some additional options with Archey. There’s nothing too fancy, but be sure to check the man page (by using man archey) to learn more about the application.

Closure:

There you have it, you have another article. This article covers how to get system information with Archey. It’s an easy and, likely, familiar task. If you’ve followed along, you’ve learned all sorts of ways to get system information.

Do you really need Archey? No, probably not… I figured I’d cover it because my site shows up in some Archey queries. If people are looking for it, it might as well be here. That’s my line of thinking, at any rate.

Let’s Find A Site’s MX Records

Today’s article is going to be rather specific and brief, as we learn how to find a site’s MX records. This isn’t something everyone is going to need to know, but it’s useful for debugging an email issue when you’re hosting websites. So, some folks are going to find it useful – and will then know how to find a site’s MX records. Read on!

I suppose most of my readers will not know what an MX record is…

In short, an MX (Mail Exchange) record is another DNS (Domain Name System) record. In this case, it is used to route emails to the correct server (via the IP address, basically). From there, your server will route the emails to individual email inboxes.

Basically, you want to know this information when things go pear-shaped with your emails or maybe when you’re using a 3rd party email service provider. There are reasons why people will want this information, they will want to find a site’s MX records.

Additionally, I figured I’d do this article now while ‘dig’ is still fresh in our memory. After all, I’ve used dig in the previous two articles and this is the final dig-related topic that I can think of. Here are the previous two articles, if you’re not reading these articles in order and are unfamiliar with the dig command:

How To: Find A Website’s IP Address
How To: Find A Site’s Nameservers

So, with all that in mind, let’s learn how to find a site’s MX records!

How To Find A Site’s MX Records:

Yes, dig is run in the terminal. Yes, you’ll need an open terminal to follow along. If you don’t know how to open the terminal, you can do so with your keyboard – just press CTRL + ALT + T and your default terminal should open.

With your terminal now open, the syntax for this specific dig command is:

For example, you’d find this site’s MX records with:

If you want, as the other dig commands used recently, you can use the +short flag with this, like so:

The output should look like this:

using the dig command to find a site's MX records
There, you can see this site’s MX records. This is public information. So, gawk away!

You can have more than one MX record, should you want failover but the mail protocol already includes some efforts to resend mail when there’s an outage. That’s irrelevant here, but information that I might as well share.

Also, like the other dig commands covered, you can put the flags at the end, like so:

So, that’s an option. I’m not sure why it’s an option. If anyone has a clue as to why it’s an option, do feel free to share. Heck, even if it’s a wild guess, I’ll take it. But, if you want more information about the dig command, run man dig in your terminal.

Closure:

There you have it, it’s another article. I think this is the last dig article, but who knows? This time around, we’ve learned how to find a domain’s MX records. For those that need to know, this will be handy.

For everyone else, you’ll likely forget this by tomorrow – and that’s okay. You don’t have to carry all the tools in your toolbox. If you tried, you’d need a very big toolbox and it’d be hard to carry it!

How To: Find A Site’s Nameservers

Today’s article will be a fun and easy one if you already understand nameservers, as I will be explaining how to find a site’s nameservers. If you don’t understand nameservers, it may be a bit more difficult. But, I’ll do my best to make it approachable. So, to learn how to find a site’s nameservers read on!

Okay, so what are nameservers?

Hmm… Let’s try to explain it in the most simple way possible… 

DNS is like a phone book. You look in the book to see which number (IP address) to connect to. However, just like in the real world (though less common with cell phones) a given telephone number may belong to multiple people.

Nameservers help to organize those DNS records. Using the nameservers is sort of like calling a phone exchange and then entering a party’s extension number to go directly to that person.

Does that make sense? No? Well, that’s the best you’re getting. I suck at analogies unless they’re automotive-related and I can’t come up with one that makes sense. I’m pretty sure the above was how it was first explained to me, or something like that. Ah well…

It should be pointed out that I used ‘dig’ in the previous article. We’ll be using that again. This time, we’ll be using dig to find a site’s nameservers instead of the site’s IP address. We might as well learn about it now, while the dig command is fresh in our memories!

Find A Site’s Nameservers:

This article requires an open terminal, like many other articles on this site. If you don’t know how to open the terminal, you can do so with your keyboard – just press CTRL + ALT + T and your default terminal should open.

With your terminal now open, the syntax for finding a site’s nameservers is as follows:

Or, if you prefer a shorter output, you have:

Like the previously used dig command, you can actually put the flags at the end (if that’s something you feel like doing). It works just fine like:

If we use this site as an example, the outcome of the latter command should look something like this:

using dig to find a site's nameservers
And there you see them, this site’s nameservers as shown by dig. Pretty easy, huh?

As you can see, nameservers look just like domain names. You’ll also note that those (shouldn’t) don’t change, unlike the site’s IP address. As we’re using a CDN, there are a number of possible IP addresses. The nameservers will be the same no matter what part of the globe you connect from.

Of course, there’s more to the dig command. We’ve just touched on a couple of uses. Check the man page with man dig to find out what other options are available.

Closure:

Well, there you have another article. Once again, we’ve used dig in this article. I figured we might as well have another dig article while I was thinking about it, and this time we used dig to find a site’s nameservers. Hopefully, this will be useful for you at some point in your Linux journey. As I deal with a bunch of websites, it’s important for me to know my nameservers and to know when they’ve propagated (something for another article).
