When you run a command at the bash prompt, it normally prints the output of that command directly to the terminal so you can read it immediately. But bash also allows you to “redirect” the output of any command, saving it to a text file so you can review the output later.
People often think of computer security as something technical and complicated. And when you get into the nitty-gritty, it can be—but the most important stuff is actually very simple. Here are the basic, important things you should do to make yourself safer online.
Windows PowerShell has a built-in command history feature that provides detailed information about the commands you’ve run. Like the Command Prompt, PowerShell only remembers your command history for the current session.
Google Chrome is based on Chromium, an open-source browser project. Anyone can take the Chromium source code and use it to build their own browser, renaming it and changing whatever they like. That’s why there are so many alternative browsers based on Google Chrome—but you don’t necessarily want to use most of them.
If you bought your PC from a vendor, you’ve likely seen the manufacturer information in the “System” window. But did you know you can change it—or even add it if you build your own PCs?
Chrome is Chrome, right? You download Google’s browser—now the most popular in the world—and you’d think you have the same experience as everyone else.

It’s ideal to have a dedicated machine for your BitTorrent client, so you can seed 24/7. But it’s energy intensive to leave a full rig powered up and online that often. Enter the Raspberry Pi.
Symbolic links, also known as symlinks, are special files that point to files or directories in other locations on your system. You can think of them like advanced aliases and here’s how to use them in MacOS.
If you’ve been trained on Microsoft Word since you started using a computer, maybe you’ve never looked at those other writing options in Windows. Notepad and WordPad are both developed by Microsoft itself, and included in every copy of Windows. Don’t dismiss them out of hand—while neither are as powerful as paid software in the same niches, they might just do for you.
Hard drives use S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) to gauge their own reliability and determine if they’re failing. You can view your hard drive’s S.M.A.R.T. data and see if it has started to develop problems.
If you live in an apartment complex, you’ve probably noticed more than just the passive-aggressive network IDs that your neighbors use—very likely you’ve had problems with your wireless connections dropping out, or just not being as fast as you’d like. This often has to do with the Wi-Fi channels in your area.
There are two groups of users worried about the temperature of their computer: overclockers… and pretty much anybody with a powerful laptop. Those things just cook you! So have you ever wondered exactly what temperature your CPU is running at?

Windows users can click the clock on the taskbar to see a calendar, which is perfect if you need to know what day of the week June 17th is. Macs don’t offer this feature, at least not out-of-the-box. But there are programs that can add one.
Windows 10, by default, sends everything you search for in the Start Menu to their servers to give you results from Bing search — so you better make sure that you don’t type anything private into your own PC’s Start Menu. Or, you could just disable the Bing integration in the Start Menu.
The latest versions of Google Chrome, Mozilla Firefox, and Microsoft Edge only support the Flash plugin. You’ll need to find an alternative browser if you want to use Java, Silverlight, or any other ActiveX or NPAPI-based plugin.
You can use Microsoft Outlook with just about any email account, including Gmail—but Outlook doesn’t provide a built-in way to sync your Gmail contacts. If you’ve amassed a bunch of contacts in either service, you’ll have to import them from the other manually to use them.

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.
Taking ownership of files or folders in Windows is not simple. Both the GUI and command line take too many steps. Why not add a simple context menu command that lets you take ownership of any file or folder?
Most web browsers are installed in Windows as 64-bit versions by default, Firefox being the exception. If you installed the default download of Firefox, you have the 32-bit version, not the 64-bit version, even if you’re running a 64-bit version of Windows.
Hey Microsoft, could you please stop breaking my PC? The latest WPD driver update released on March 8, 2017 is just the latest in a long string of bad updates. If Windows 10 is going to force these updates on my system, the least Microsoft could do is test them properly first.
Amazon can notify you about purchases, shipments, and delivery delays by email, text message, or push notifications from the Amazon app. It’s even possible to enable all three types of notifications, and you’ll be bombarded with duplicate notifications whenever you order something.
