When Did I Install Lubuntu

This won’t be a complicated article, nor will it be a very long article, as we answer the question of, “When did I install Lubuntu?” It’s a rather specific question and one you can answer with a couple of different commands. Fortunately, this is also going to apply to Ubuntu, Mint, Debian, and all the rest that are set up in this manner.

You may not recall the exact date and time when you installed Lubuntu. That’s okay, most of us don’t keep track of that information. At some point, you may want to know that information. It’s not a major data point, but knowing when you installed Lubuntu can be useful.

Yes, this article is about Lubuntu. It’s specific to Lubuntu because I use Lubuntu as I type this. There are other distros where this will work perfectly well. Tomorrow is my birthday and I’m not going to test a bunch of distros.

If you’re unfamiliar with Lubuntu, it’s a Linux distro that I’m a big fan of. It’s not the best Linux distro, it’s the best distro for me. I’ve written a whole lot of Lubuntu articles!

(And many more Lubuntu articles…)

Lubuntu is a great distro that has a familiar interface, great support, a wonderful community and is easy to adapt to. A Windows user can be up and running Lubuntu in an hour – if they take their time. As I say, “Things are where you’d logically expect them to be.

Anyhow, the question is when did you install Lubuntu…

When Did I Install Lubuntu:

This is going to require an open terminal. As we’re using Lubuntu, you can open your default terminal by pressing CTRL + ALT + T on your keyboard. The tools you need will be already installed.

Now, you can identify your storage drives with lsblk but we’ll use the following command, as it’s easier for this task.

From there, you want to find your / partition. For example, here’s my output:

In this case, the output is /dev/nvme0n1p1 and not any of the other choices.

If you were using something like Mint, the output might be similar to this:

In that case, the output is /dev/sda2 largely because I’m using UEFI on that system and the first partition is occupied with that data.

The syntax you’re looking for to find out when you installed Lubuntu is pretty simple. You have two choices that will work. They are as follows:

Or:

So, on my Lubuntu system, the command would look like:

While on Mint it would look like this:

Of course, you can switch it up with the dumpe2fs command, per the instructions.

NOTE: This works on ext* formatted partitions. If you did some sort of weird, non-default, installation, then it may not work for you. I can’t be 100% certain because I didn’t test this.

The tools we’ve used are tune2fs, which is already installed and is described as:

tune2fs – adjust tunable file system parameters on ext2/ext3/ext4 filesystems

And, we’ve used the dumpe2fs command which is already installed and described as:

dumpe2fs – dump ext2/ext3/ext4 file system information

So, I can only assume that other drive formats aren’t going to work and that information simply won’t be stored. They might work. I simply do not know and haven’t taken the time to look into it. That means this will work for the vast majority of users.

Closure:

If you have ever asked yourself, “When did I install Lubuntu?” This is the article for you. I admit, it’s rather specific, but it is what it is. If you want to try this with other systems, go ahead! It won’t break anything and it just might work. If you’ve partitioned your drives with a different formatting, it’s probably not going to work but trying these commands will not break anything.

Find Out If A Package Is Installed In Debian

Today we’ll have a quick and easy article where we find out if a package is installed in Debian. There are times when you’re unsure of which packages are already installed. Today’s article looks to help with that, letting you know how to find out if a package is already installed.

Depending on where you live, yesterday was a holiday. A nice and easy article seems like a good idea. It’s actually a holiday as I write this, but that’s okay. I’d probably have written it ahead of time but Mother Nature was having her way with me and my neighbors. So, this is being written on Christmas Day. That’s another good reason to keep this short.

If you’re unaware, Debian is a Linux distro. Debian is one of the elders among distros, having just turned 30 not long before writing this article. It’s a very popular distro that has stood the test of time.

Debian also has a whole lot of derivatives. Then, there are derivatives of Debian derivatives. For example, there’s Ubuntu (and all the flavors) which has many derivatives, such as Linux Mint. While less common, there are probably derivatives of derivatives. By now someone has probably at least made a derivative of Linux Mint! (I did not look.)

That means that today’s article will apply to almost all of them. There’s bound to be an outlier, but anything still using apt or dpkg is good to go and will be able to use the information in this article. You won’t need to install anything, but you will need an open terminal.

Find Out If A Package Is Installed In Debian

Today’s article will involve the terminal. You can easily use a GUI for this. Just open your software manager to search for the package name. In this case, we’ll use a terminal and you can usually open your terminal by pressing CTRL + ALT + T.

You won’t need to install anything to determine if a package is installed in Debian. Everything you need, all the tools you’ll need, should be preinstalled. The tools you’ll be using:

dpkg:

You can use dpkg as one tool for this job. Given my preferences, this is the tool I’ll use for this job, simply because I like the output better. If you check the man page, you’ll see dpkg is described like so:

dpkg – package manager for Debian

That’s a pretty good-sounding description for the task. After all, we want to find out if a package is installed in Debian.

The syntax to do this with dpkg is quite simple:

For example (in Mint):

As you can see, Firefox is indeed installed. You should also remember that this operation is case-sensitive. This generally means you want lowercase letters.

apt:

You can also use apt to find out if a package is installed in Debian. If you don’t already know, apt is one of the tools you can use to manage packages in Debian. Think of apt (and apt-get, the stable cousin) as a front-end for Debian’s dpkg. The man page isn’t all that descriptive at first:

apt – command-line interface

But, if you look a little further, you’ll see:

apt provides a high-level commandline interface for the package management system.

So, apt is another fine tool to use for finding out if a package is installed in Debian. It too has a rather simple syntax and it looks like this:

For example (in Mint):

In this case, you can safely ignore the warning. Again, this is case-sensitive and you’ll almost certainly want lowercase letters in your command.

Closure:

See? A nice and easy article for you. It’s not all that difficult to find out if a package is installed in Debian. This is something you can do quite quickly with an open terminal emulator. It’s something easy enough to remember, as well.

Today’s article was nothing too taxing and is something that can come in handy because, if you’re like me, you can’t possibly remember all the packages you’ve installed. Then, when you do install packages, you’re often installing dependencies.

Keeping track of all of those packages manually would be a tedious process! Just a little bit of terminal knowledge makes quick work of this and the commands are easy enough to memorize. Try them a few times and you might just remember them by rote.

Monitor Progress With RSYNC

When you’re moving a lot of files around you might want to know the progress, so here’s how you monitor progress with rsync. This will likely be an intentionally short article, an easy article, as it’s another weekend article – this time about rsync and how you can monitor the progress.

The rsync application is a tool for transferring and synchronizing files between two places. It’s a very handy application and rsync has a whole lot of features. It’s possible to write a half-dozen rsync articles and not even scratch the surface. We’ve had rsync available since the mid-90s and you can visit the rsync project page.

You’ll almost certainly not need to install anything to use rsync. It’s pretty much available with every distro though I’ll mention ahead of time that this is a terminal-based application. By the way, if you’re not happy with your terminal, you can change to a new default terminal easily enough.

There are frontends for rsync, such as luckyBackup, but we’ll just be using a plain old terminal for this article. If you play with luckyBackup, you’ll discover that you can use it to spit out the actual rsync command you’ve configured and use it in the terminal without any additional overhead.

RSYNC:

If it’s not obvious, the tool we’ll be using is rsync. Specifically, we’re going to monitor the progress as rsync synchronizes your data from one place to another. It’s going to be a very easy article, I promise. Well, I think it’s easy. I suppose I could be wrong and you find it more difficult.

You shouldn’t need to install anything to follow along. You can first verify that you have rsync installed and available. Use this command:

If you don’t have rsync available immediately, I’m sure you can install it from one of your default repositories. If it’s not installed by default, let me know. I’m curious…

Anyhow, you can check the man page (with man rsync) to learn more about this application. It’s a rather long and complicated man page, but rsync is described as:

rsync – a fast, versatile, remote (and local) file-copying tool

And that’s what we want to do. We want to monitor the progress of file transfers. So, that’s what we’re going to do.

Except, I’m also going to show you how to make a simple backup of your data as a bit of bonus information. Let’s get on with it!

Monitor Progress With RSYNC:

Now, I did tell you that you’ll need an open terminal for this. That’s easily done. More often than not, you can open your default terminal by pressing CTRL + ALT + T. Otherwise, you can find it in your application menu.

With your terminal now open, your standard command would be something like this following rsync command:

To monitor progress with rsync, you’d add the --progress flag, like so:

That’s all well and good, but let’s pretend you want to make a backup of your home directory with rsync and that you want to monitor the progress. Well, you can happily use rsync with directories. This is going to be pretty easy!

The -r flag means ‘recursive’. That means it will include the files in the directory you specified, find the additional directories within that directory, and include those files. It will keep digging until there are no more directories unless you decide to specify a maximum depth.

Let’s further assume you have a USB device plugged in and you want to store your home directory on that USB. Let’s also assume that the USB’s called ‘backup’. The command for that would just be something very close to this command:

That might look something like this:

showing the progress of rsync
As you see, it’s easy to monitor the progress of rsync. Yes, that’s Windows ME. Don’t judge me!

That command will move all the files from your home directory (as we know that ~/ is a short way to say your /home/user directory) to your USB device. You’ll have then backed up your personal data. The second time you run it, it will sync those files – only replacing those files that have changed since the last time you ran the command.

You can easily use that command (modified for your needs, of course) to make a backup of your home directory. This is the most important data on your system. The rest is just system files and those are easily restored with a fresh installation.

While it would be possible to use rsync to backup the entire drive, it’d try to do stupid things like backup the /media directory. You’d need an advanced command for that and that’s beyond the scope of this article.

As it stands, the backup bit is extra. This article is just about how you can monitor the progress with rsync. It’s a pretty trivial thing, but something you can learn about quickly.

Closure:

Yeah, it’s a pretty short and easy article. At least I hope it’s easy. I did make a promise, after all! This one should be easy enough for anyone because it’s not all that hard to learn how to monitor progress with rsync. Also, with a reasonably large file, you can do things like check transfer rates, be it over a network or from one drive to another. There’s all sorts of fun!

Reboot From The Terminal

The weather has had a bit of an impact on my internet connection, so this is just going to be a quick article about how you reboot from the terminal. I want to schedule this as soon as possible, so it’ll be a fairly low-effort article. This should not take long!

There are times when you may want to know how to reboot from the terminal. Then, there are times when you can’t access a GUI, and using the terminal is the cleanest method of rebooting your computer. Knowing how to reboot from the terminal might be a skill worth having. I’ll show you a couple of quick and easy ways to do this.

As the title says, this is going to take place in the terminal. You can usually just press CTRL + ALT + T to open your default terminal. You could otherwise reboot with REISUB.

So, with your terminal open…

Reboot With systemd:

The first command we’ll use to reboot your computer. We’ll be using systemd. This will only work if you’re using a distro with systemd.

Reboot With shutdown:

It should be fairly obvious that the shutdown command can be used to reboot your computer. This is one of the generic utilities, so you won’t need to install anything.

(Check the man page because there are a lot of options available.)

Reboot With reboot:

Finally, we’ll use the reboot command to reboot your computer. This might be the easiest to remember and you shouldn’t need to install anything new. You need the following command:

In some distros, you can drop the ‘now’ and the command will still reboot your computer immediately. 

Closure:

So, there you have it. You have a new article and it should even be published on time. It’s not a long article. The subject is easy enough. You’ll never know when you need to reboot from the terminal, and now you do.

Ah well…

Automatically Enable Num Lock In Linux Mint

Sometimes I write articles that scratch my own and this time around it’s how to automatically enable Num Lock in Linux Mint. If you’re using a full-size keyboard and want to automatically enable Num Lock, this just might be the article for you. This article shouldn’t be all that long – and it won’t be very complicated. 

I should explain…

So, I misfired a dd command and hosed my root partition. I then decided to do something I’ve not done in a long time. For a change of pace and a fresh start, I decided not to restore (much of my) data from backups. Sure, I imported passwords, Thunderbird, ~/bash_aliases, and remained logged into browsers, but I didn’t import all my settings, my million browser tabs, or anything like that.

It has been fun! I haven’t done this in a long time. If I hose an OS, I just install and copy my /home directory into the freshly installed OS and I’m good to go.

As an aside, I’m quite grateful that I’ve written these articles. They’ve come in handy while rebuilding my system. I find myself referring to this site quite often. After all, I tend to write about what I know. These are often articles of things I do. This time around, it’s simply how you can automatically enable Num Lock in Linux Mint. This shouldn’t take long.

Disable The Caps Lock Key In Linux Mint

Automatically Enable Num Lock In Linux Mint:

You don’t need an open terminal for this, but we’ll use the terminal because it’s easier for me to do this in the terminal. You can start by pressing CTRL + ALT + T to open your terminal.

With your terminal now open, we’re going to install an application called numlockx.  This is required if you want to use this method of enabling Num Lock automatically. 

If you check the man page, you’ll see that this is the tool we want for this task.

numlockx – Control the state of NumLock

Sure enough, that’s what we want to do! The rest is all in the GUI.

Open your menu and search for “login”. You’ll see an application called Login Window. Open that and then click on the Settings tab. With that Settings tab open, tick the slider to automatically enable Num Lock when you log into the system. It looks like this:

it's easy to automatically enable num lock in Linux Mint
That’s really all there is to it, so long as you first install numlockx. See? I told you it was easy!

That is what your screen should look like to enable Num Lock. This is it at the login window portion of the boot. This means you’ll have the Num Lock enabled and won’t have to remember to press the button when you use it.

Closure:

See? I told you this one would be quick and easy. Like I said, I’m just scratching my own itch. I prefer the Num Lock key to be enabled all the time. It’s just a habit for me and I do use the number pad fairly often. I figured I’d share it, seeing as it was something that was on my mind.
