Android phones and tablets can fill up quickly as you download apps, add media files like music and movies, and cache data for use offline. Many lower-end devices may only include a few gigabytes of storage, making this even more of a problem.
Groups help define the permissions and access your Linux user account has to files, folders, settings, and more. Finding out the groups to which a user account belongs helps give you a better understanding of that user’s access (and troubleshoot when things don’t work right).
Most modern computers are capable of running a 64-bit operating system. But just because a computer supports it doesn’t mean that’s what’s running. Here’s how to tell whether you’re running a 32-bit or 64-bit version of Linux.
This trick should work on all Debian-based Linux distros, including Ubuntu. To get started, type ifconfig at the terminal prompt, and then hit Enter. This command lists all network interfaces on the system, so take note of the name of the interface for which you want to change the IP address.
Back in the early days of Android, system updates were very random: they would roll out at different times, and often several times per year. Now, Google has taken a much more streamlined approach, releasing one major Android update per year and much smaller, security-focused updates once per month.
For years, Android enthusiasts have been rooting their devices to do things that Android doesn’t allow by default. But Google has added many features to Android that once required root, eliminating the need for many people.
When you picked up your shiny new Android device, you probably thought “yeah, this has plenty of storage. I’ll never fill it up!” But here you are, some number of months later with a full phone and no clue why. No worries: here’s how you can figure out where the space hogs are.
Sometimes it’s necessary to grab a still image of what’s happening on your device’s screen—that’s called a screenshot. While this used to be a hassle on Android (many moons ago), all modern handsets include the capability. Here’s how to do it.
Android is very customizable–many of its features are just defaults, and can be swapped out for third-party alternatives without any rooting required. When it comes to iOS, well…not so much.
At this point, smartphones are prolific. We use them for calls, text messages, social networking, photos, quick searches, streaming music, watching videos…the list goes on. But each thing you do drains your battery life, and some apps will even continue to drain your battery in the background when you aren’t using them. A free app called Greenify can fix that.
If there’s an Android application you really love and wish you could run on your computer, now you can: there’s a dead simple way to run Android apps on your PC or Mac without the fuss of moonlighting as an Android developer.
If you’re dual booting Windows and Linux, you’ll probably want to access files on your Linux system from Windows at some point. Linux has built-in support for Windows NTFS partitions, but Windows can’t read Linux partitions without third-party software.
Most people use a graphical file manager to find files in Linux, such as Nautilus in Gnome, Dolphin in KDE, and Thunar in Xfce. However, there are several ways to use the command line to find files in Linux, no matter what desktop manager you use.
Ubuntu and many other Linux distributions use the GRUB2 boot loader. If GRUB2 breaks—for example, if you install Windows after installing Ubuntu, or overwrite your MBR—you won’t be able to boot into Ubuntu.
Virtual machines are demanding beasts, providing virtual hardware and running multiple operating systems on your computer at once. As a result, they can sometimes be a little slow. Here are some tips to help you squeeze every last drop of performance out of your virtual machine, whether you’re using VirtualBox, VMware, Parallels, or something else.
Web browsers you use on your mobile phone or tablet remember your browsing history, just like browsers on your PC or Mac. Anyone who borrows your phone or gets access to it somehow can see which webpages you’ve visited. However, it’s easy to protect yourself.
On occasion you will need to edit the hosts file on your machine. Sometimes because of an attack or prank, and others so that you can simply and freely control access to websites and network traffic.
The bash shell is the standard terminal environment included with most Linux distributions, included with macOS, and available for installation on Windows 10. It remembers the commands you type and stores them in a history file. You probably know a few basics of the bash history, but it’s a lot more powerful than you might realize.
Manufacturers and carriers often load Android phones with their own apps. If you don’t use them, they just clutter your system, or–even worse–drain your battery in the background. Take control of your device and stop the bloatware.
Bash is the default command-line shell on most Linux distributions, from Ubuntu and Debian to Red Hat and Fedora. Bash is also the default shell included with macOS, and you can install a Linux-based bash environment on Windows 10.
When you delete sensitive files from your Dropbox account, you may think you’ve deleted them permanently. However, the files remain in a hidden cache folder on your hard drive for efficiency and emergency purposes that is cleared automatically every three days.
If you’ve tried to install Google Chrome in Ubuntu Linux, you may have noticed that it’s not available in the Ubuntu Software Center. However, it’s easy to download a package file for Google Chrome and install it on your system, and we’ll show you how.
Most Linux distributions include the bash shell by default, but you could also switch to another shell environment. Zsh is a particularly popular alternative, and there are other shells, like ash, dash, fish, and tcsh. But what’s the difference, and why are there so many?
When formatting partitions on a Linux PC, you’ll see a wide variety of file system options. These options don’t need to be overwhelming. If you’re not sure which Linux file system to use, there’s a simple answer.
Android isn’t largely thought of as a desktop operating system, but if you’re curious about how Google’s mobile OS works, running it on a device you already have isn’t a bad idea. This will give you an idea of what to expect on a phone or tablet, all without making a single change to your laptop or desktop since you can easily do this from a flash drive or memory card.
