I was messing around with my Ubuntu system the other day, trying to tidy things up a bit. You know how it goes – I got curious about what services were actually running in the background. I’ve heard of systemctl, but honestly, I feel like there are so many commands and options that it can be a bit overwhelming at times. I mean, do I need to be a Linux guru just to figure out what’s going on with my services?
So, here I am, navigating through the terminal, and it hit me: how do I actually view all those currently active services? I tried a couple of basic commands, like `systemctl status`, but that only seems to show me the status of the services I’m specifically interested in, and that’s not giving me the full picture I’m looking for. I want to see everything that’s running – the good, the bad, and the ugly!
I’ve heard that there’s a way to filter them down or maybe even categorize them, but I’m not quite sure how to do that. Like, do I need to use some kind of flags or options with the command? And what about those services that are currently inactive? Should I be concerned about them as well?
Honestly, I read somewhere that there are plenty of services running that I might not even need. I’d love to hold onto my system’s performance, and knowing what’s active is probably a good first step in that direction. Plus, I’m a bit of a neat freak when it comes to things running behind the scenes – it just feels good to know what’s going on under the hood, you know?
If any of you have tips on the command I should run or maybe even some tricks to give me a clearer picture of all the active services, I’d appreciate it! It’d save me a lot of headaches, and maybe I’ll even learn a thing or two in the process. What do you say—how can I get the scoop on those active services in systemctl?
How to View Active Services with systemctl
If you’re diving into the world of Ubuntu and want to check out what services are running,
systemctlis your best buddy! Sure, it can feel a bit overwhelming at first, but once you get the hang of it, it’s actually pretty straightforward.View All Active Services
To see all active services, you can use this command:
This will give you a nice list of all services that are currently running. You’ll get their names, along with a brief description of what’s up with them.
Viewing Inactive Services
If you’re curious about services that aren’t running right now (inactive), you can use:
Seeing these can help you figure out if there’s anything you don’t need starting up with your system.
Filtering Services
Want to filter or categorize services? No problem! You can use different flags. For instance:
This will show you all services, whether they’re running, failed, or inactive. It’s like getting the full scoop!
Are Inactive Services a Concern?
As for the inactive services, it’s not usually a big deal unless there’s something you specifically know you should be running that isn’t. Sometimes, it’s just part of the normal operation. But if you’re a neat freak like you said, it’s good to regularly check in on them!
Keep Your System Lean
If you want to keep your system’s performance in check, knowing what’s running is definitely a great start! You can even disable some of the services you don’t use. Just be careful and make sure you know what you’re turning off!
So, go ahead and give those commands a whirl! Experiment a bit, and you’ll soon feel like a pro navigating those services in no time.
To view all currently active services on your Ubuntu system, you can utilize the `systemctl` command along with some specific options that will give you a clearer picture. The command you want to use is
systemctl list-units --type=service --state=running. This command will display all running services, filtering by their type as ‘service’ and their state as ‘running’. If you wish to see not just the active services but also those that may be inactive, you can modify the command tosystemctl list-units --type=service. This provides a more comprehensive overview, including those that are failed and inactive, allowing you to assess which services may be taking up resources unnecessarily.If you’re looking for more details on each service, such as their description and status, you can append the option
--allto the command:systemctl list-units --type=service --all. This will display all units regardless of their state. It’s wise to regularly review the status of these services to ensure that you’re not running unnecessary ones that could degrade your system’s performance. By familiarizing yourself with these commands, you’ll gain greater control over your system’s background processes and be able to clean up services that you don’t require, maintaining optimal performance.
