LINUX IS CONFUSING. THESE ARTICLES SHOULD HELP.
Enclosing text in quotation marks is fairly standard practice on the command line, especially when dealing with files that have spaces in the names, but how do you know whether to use single or double quotes? Let’s take a look at the difference, and when you should use one vs the other.
If you’ve added a PPA and run into a nasty bug in your updated software, you should revert back to the Ubuntu repositories. Doing it safely can be tricky – fortunately Ubuntu Tweak can do this for us.
It doesn’t matter if you are using Windows, OS X, or Linux, everyone should do regular backups of their information. In Linux one of the easiest ways to do automated backups is with Simple Backup (SBackup). Here is how you can set up SBackup to make sure you have a backup of all your important files.
Ubuntu gets its stability from heavily testing new versions of software. However, if you want to risk some instability and try out the latest versions of your favourite programs, we’ll show you how!
The bloggers over at cloud-storage service SpiderOak have posted an awesome image depicting a tug-of-war contest between the Ubuntu mascots (plus the SUSE Gecko) and the various cats representing Mac O.S. releases.
Connecting to file servers is something most people do on a daily basis even without thinking about it. In Linux, it may not be intuitive how to quickly connect to a samba or ftp server without a separate program. Here are a few different ways to connect to a remote file server without needing to touch a terminal.
What do you get when you mix up a good dose of nostalgia and the new purple color for Ubuntu’s default wallpapers? These two wonderful looking wallpapers that will add a touch of style to your Ubuntu install.
If you’re anything like me, you probably have Ubuntu running on your older computers, and they often have smaller hard drives so you’re looking to save every bit of drive space you can. Here’s an easy trick to free up a surprising amount of drive space.
If you are looking to upgrade the memory in your Linux PC, you are probably wondering how many open slots you have, what type of memory is already installed, and what you need to buy for an upgrade… without having to open your computer.
One of the nicest things about Linux is the variety and number of distributions available for people to use. This week we want to know which Linux system is your favorite.
The upcoming release of Ubuntu, scheduled for final release in October, will bring some new interface improvements including a different Netbook edition.
Virtually all linux distributions include sendmail as the default MTA. Which is okay – it has been around for a long time, is stable and it works great (although the postfix afficionados might disagree!). But it has nothing built in for spam control which is good; it was not designed for that. So you’ve installed spamassassin and it works good but you still are getting unflagged spam emails through. Perhaps you need to try greylisting.
When you’re running production servers, the one thing you don’t want to do is upgrade the kernel every time a new update comes out. Why? Because that’s the only Linux update operation that requires a reboot once it’s done—and in a production environment you often can’t have downtime.
If you’ve worked in the admin world for any length of time, you’ve probably run into an instance where you needed to change the hostnames on your server to match some corporate naming standard, but you can’t have downtime either. So how do you change the hostname without rebooting?
If you have been an admin for any length of time, you have certainly discovered situations where a server spikes in CPU use or memory utilization and/or load levels. Running `top` won’t always give you the answer, either. So how do you find those sneaky processes that are chewing up your system resources to be able to kill ‘em?
Linux distributions like Ubuntu open the main menu with Alt+F1 instead of the Windows key that most new Linux users would be expecting, but it used to be simple to change the shortcut key. Since Ubuntu 9.10 the process isn’t so obvious, but we’ve got the instructions for you.
We’ve already shown you how to customize shortcut keys in any Linux application, but for today’s lesson we’ll take it a step beyond—and assign a shortcut key that switches an open application to be the currently focused window.
Ubuntu has an easy way to keep your system clock synchronized with the internet time servers, but sadly it’s not enabled by default. Here’s the quick steps required to enable it for your system.
