This is how the -c flag works: grep -c "fruit" fruits.txt We can count the number of times the matched string appears in the file. How to Count the Number of Occurrences of the Provided Pattern using -c This would include occurrences like "grape fruit", "dragon fruit" and so on like this:īut, if we only want "fruit" in our results, we can use the -w flag like this: grep -w "fruit" fruits.txtĭo you see the difference? The latter result returned only one line where the exact word "fruit" was found. If we grep "fruit" without any flags, it would return any occurrence of the word "fruit". If you were to match an exact word rather than just the occurrence of a pattern, you can do so by using the -w flag. How to Find the Exact Matching Word from the Input File or String using -w For that, we can supply the -n flag to grep like this: grep -n "berries" fruits.txtįrom the output, we can see that the word "berries" occurs on line #5 of the file. There are times when we want to get the line numbers against the matching string. How to Find the Line Numbers Against Matching Input using -n The output returned all the lines that do not contain "berries". Let's say, if we want to get all the lines that do not contain the word "berries", the command would look like this: grep -v "berries" fruits.txt We can reverse the results of the grep command to include non-matching results. Output: How to Select the Non-Matching Lines using -v It should match all occurrences of "berries" regardless of their case. Let's find the word "berries" from our sample file. We can command grep to return results while ignoring the case of the matching string. Here's the output: How to Ignore Case Distinctions using -i If we want to find the string "fruit" in the file fruits.txt, we can do so like this: grep "fruit" fruits.txt Contents of fruits.txt How to Find a Matching String with grep Melons – watermelons, rockmelons and honeydew melons Tropical and exotic – bananas and mangoesīerries – strawBERRIES, raspberries, blueberries, kiwifruit and passionfruit Stone fruit – nectarines, apricots, peaches and plums In the coming examples, we will use the file fruits.txt with the following content: apples and pearsĬitrus – oranges, grapefruits, mandarins and limes -c: Count the number of occurrences of the provided pattern.-w: Find the exact matching word from the input file or string.-n, -line-number: Prefix each line of the matching output with the line number in the input file.-v, -invert-match: Selects the non-matching lines of the provided input pattern.-i, -ignore-case: Ignores case distinctions in patterns and input data.In this article, we will discuss the following options that can be used with grep: It is a good practice to close the PATTERN in quotes when grep is used in a shell command. Grep finds each line that matched the provided PATTERN. In the above syntax, grep searches for PATTERNS in each FILE. The syntax of the grep command is as follows: grep PATTERNS Grep syntax In this article, we will discuss the grep command's syntax and its usage with some examples. If you are a system admin who needs to scrape through log files or a developer trying to find certain occurrences in the code file, then grep is a powerful command to use. grep is short for "global regular expression print". Grep is a useful command to search for matching patterns in a file.

You can also play music with your preferred media player, or use keyboard shortcuts to do so. If you want to control how playback is controlled on your Mac, use the Window menu’s AirPlay Mirroring controls. When you select your Apple TV from the list, it will start copying data from the screen to your Mac. To use this feature, ensure that your Mac and Apple TV are on the same network and launch the Screen Mirroring icon in the Control Center. It is a great way to show off your work or enjoy a game you like on a large screen while also using AirPlay Mirroring. To enable Fast TV Start on your Roku TV or soundbar, go to Settings. Swiping left or right will quickly change the image you’re looking at pick a Roku and begin casting. Tap the Share icon (a rectangle with an arrow rather than a triangle) in the Photos app to launch the iCloud feature. To stop mirror operations, go to Control Center and select Screen Mirroring. If casting isn’t an option in your app (such as Twitch), or if you’re simply attempting to include a nearby interface, you can use mirror. Screen Mirroring replicates a phone’s or computer’s output, including its interface elements, in real time. In addition to Siri and the Apple Home app, Roku can be controlled using HomeKit, though this is not an option. To mirror Roku to an iPhone, iPad, or Mac, you must first enable AirPlay on your Roku device. If Roku does not support AirPlay, you may need to restart your devices and check your Wi-Fi connection.Īpple’s AirPlay can be found on nearly all Roku devices running Roku OS 9.4 or later. You will require an Apple device capable of AirPlay and a Roku model that supports it in order to use it. If you don’t see your Roku device when attempting to use iOS to view content on your TV, you should double-check the following: Can You Airplay From Mac To Roku Tv?Īpple’s iCloud service allows you to stream content to your Roku from your iPhone, iPad, or Mac. Once playback has begun, you can pause, fast forward, and rewind on your iPhone, iPad, or Mac, or you can use your TCL Roku TV remote to pause, fast forward, and rewind. Furthermore, Screen Mirroring from Control Center on your iPhone or iPad can be used to mirror any video that is being viewed on your Apple device. When you turn off your TV, it may not be able to stay connected to your wireless network. You can share music with your Roku TV and any other AirPlay 2-enabled speaker by using both your Roku TV and the speaker. You can stream your TV shows, movies, videos, and photos directly to your Apple device using iOS’s AirPlay feature. TCL Roku TVs are now compatible with Apple Airplay and HomeKit. From there, select your tcl roku tv from the list of available devices and the content should start playing on your tv. Then, hover your mouse over the video content window and click on the Airplay icon that appears. Once that is done, simply open up the desired content on your mac that you want to watch on your tcl roku tv. In order to airplay from mac to tcl roku tv, you will need to have both the mac and the tcl roku tv powered on and connected to the same wifi network. Its high speed test scores may make these activities possible. Perhaps it's video streaming, incredibly exact location spoofing, or something similar. CyberGhost does provide servers in countries with oppressive internet rules, including China, Hong Kong, Russia, Turkey, and Vietnam.ĬyberGhost is best suited for someone who need a VPN for certain activities due to its massive server list. While the great majority of its servers are in the UK and US, it still has a decent worldwide mix, with a better-than-average showing for Africa and South America, two regions that are sometimes overlooked by VPN providers. CyberGhost has around 7,000 servers in 91 countries, making it one of the largest and most diverse services we've assessed. Larger server networks might also increase your chances of locating a server near you. The more server locations a VPN provides, the more options you have for selecting the best server and faking your location. That's a little concerning for a Windows-only antivirus software, but we'll reserve judgment until we verify the performance of CyberGhost Security Suite for Windows. When we previously assessed Intego's Mac software in 2017, we found that it scored very poorly in third-party lab tests for identifying Windows malware. We were startled to see that the CyberGhost VPN's antivirus is powered by Intego, a Mac-only antivirus vendor. This feature is available to anybody with a CyberGhost VPN subscription, however it is only supported on Windows 7, 8, or 10 systems. Under the hood, Security Suite for Windows contains Intego antivirus protection, a Privacy Guard application meant to secure your information from Microsoft, and Security Updater, which monitors your programs for updates. The final price is determined on the length of the subscription. The most significant addition to the CyberGhost arsenal is CyberGhost Security Suite for Windows(Opens in a new window), which costs an extra $5.99 per month when a VPN subscription is purchased. We will update our review after we have had the opportunity to test the NoSpy servers. We were unable to test NoSpy servers since they cannot be added to an existing subscription. ProtonVPN, on the other hand, employs its Secure Core servers for multi-hop connections, whilst CyberGhost does not. In addition to greater physical security, this is identical to ProtonVPN's Secure Core servers. However, the service is pricey, has yet to be audited by a third party, and lacks the full array of VPN capabilities we've come to expect from top-tier offerings.ĬyberGhost VPN provides NoSpy servers, which it claims are specifically tuned servers at a high-security server facility in CyberGhost's home country of Romania. It has also expanded its reach beyond VPNs by including additional security measures. It has the largest network of VPN servers we've seen so far and supports up to seven simultaneous connections. It's a potent weapon, and CyberGhost is one of the best VPNs we've used. A VPN preserves your privacy by encrypting your web traffic and directing it to a distant server, protecting your personal information and making you tougher to follow online. Signal offers a few must-have features for any proposed application. Signal offers high-end security features and ensures that privacy remains intact. Features offered by Signal app- Must-have for any Messaging App Any proposed messaging application should pick the security parameters followed by the Signal application. While developing an application, we must keep all these parameters in mind. Here, we can say that Signal fulfils all the requirements of EFF and that is the reason why it is considered as one of the most secure messaging applications in the market.
Now you will be able to virtually fly through a resort, or see a marketplace or historical district before your visit. Only recently have we been able to see a hotel room or a beach in a 360 photo before booking a trip. Think about how the tourism industry will capitalize on this. Just consider a couple of the many possibilities here. What happens when this eventually comes to the low-priced Daydream View headset? Or a mid-range device that Google is rumored to be working on? At that point it will available to everyone just as Street View is today. But Oculus Rift is a likely choice in the near future. No word yet on when we’ll see Google Earth VR in other VR headsets. Think back to those early versions of Google Maps or MapQuest that we once found so exciting and useful. This is just the first step to turning earth’s entire expanse into a virtual reality experience. In UpLoadVR‘s memorable description, it has a bit of a Nintendo 64 aesthetic.īut that will change. In addition, detailed areas are currently limited and they can warp and blur as you get closer to the ground. So while it’s easy to see a landmark, finding a street address will depend on your prior knowledge of a place.īut no matter – you’re going to have loads of fun getting there. And street names are missing with no way to type in an address. As you might expect, coverage of urban areas in the West is more extensive than cities in the rest of the world. That’s impressive, but a good part of the earth’s land mass and lots of well-known cities are still missing. There are around 175 cities with full, 3D data, and over 600 ‘urban cores’ as well. 54 percent of the Earth’s land mass is covered. 94 percent of the world’s population is covered in this experience. According to Mike Podwal, project manager for Google Earth VR, More details to comeĭespite the glowing reviews, there’s a few limitations at the moment. That type of power makes the full implications of Google Earth VR truly staggering. Google Earth VR does not require an army of animators to build each building in San Francisco through Unity or Unreal Engine 4, it is fueled by an always refreshing data set from one of the world’s most powerful sources of geographical information. And there’s no need for a floor full of developers cranking out 3D objects in Unity. It’s a VR development without the release of new hardware. What makes Earth VR so powerful is that it leverages the massive amount of data already collected for the Google Earth project. the godlike virtual reality experience we’ve been waiting for. Google’s new project is a stunning development for virtual reality. Google’s very short promo video gives you a taste of what to expect: The field of view narrows to counter the potential for motion sickness, but you can make adjustments in the FOV if you want the full experience. You’re fluidly moving around the earth, not jumping from one point to the next, transporter style. Turning slowly I can almost feel the wind in my hair but I know that couldn’t be possible. I aim for the lid of the famous mountain’s bowl-shaped depression and land smoothly on the craggy ground. In the blink of an eye the world around me dissolves and the restaurants of East Fourth Street are replaced by the brilliant purple face of Japan’s Mt. I haven’t seen my hometown in almost a year but even the pull of nostalgia isn’t enough to keep me entertained forever. Joe Durbin captures the essence of the experience in UpLoadVR. Fly through a city, stand on a mountaintop, or plunge into the depths of a canyon. Grab your headset, the Vive hand controllers and be ready for a breathtaking experience. Earth VR turns the entire world into a Virtual Reality playground and learning resource. It’s available for free in the Steam Store for the HTC Vive. Google Earth VR was the surprise announcement on the Google Blog last week. It's hard to definitively say which mode is worth picking: I spent most of my play through on performance since 60fps matters most to me, but the ray-traced shadows and ambient occlusion are a genuine highlight on console. The effects can be transformative then, but the trades to both resolution and performance are steep. Performance on both PS5 and Series X sticks unerringly to 30 frames per second on this mode, too. With ray-traced shadows enabled, character shadows also logically become more diffuse, the further away they get from the light source. Plant-life is transformed with an extra layer of shade. The leftover GPU horsepower is instead funnelled into ray-traced shadows and ambient occlusion, adding significantly more depth and realism in outdoor scenes especially. Lastly then, we have the quality mode, which retains the 30fps of the resolution offering, combined with a 1080p resolution. Series S? Think of its single 30fps mode as a slightly less stable version - still very consistent, but a little more prone to screen-tearing. In this respect, PS5 and Series X run in a very similar way. You are effectively getting a fully locked 30fps in this mode, however, with only very, very minor dips beneath this with isolated effects (such as jumping into water). It is an advantage for the Microsoft machine, but a limited one in practical terms - a touch of extra clarity is delivered, especially on transparent elements, but in truth, it's hard to tell the difference side-by-side. That's a 16.6 percent increase in pixel-count for Series X, just slightly beneath the compute differential between the two consoles' GPUs. Next up, there's the resolution mode which dramatically increases clarity in the image, thanks to a bump to 3200x1800 on PlayStation 5, rising to 3456x1944 on Xbox Series X. It should be available soon and we'll report back on how well it functions. There are reports of a variable refresh rate mode exclusive to Series X that unlocks the frame-rate on 120Hz screens but unfortunately, this was not functioning during the review period. Even so, the improved performance brings out the best in the sense of weight and movement in the game's parkour segments. However, the combination of the relatively low resolution and the temporal anti-aliasing solution ensure that presentation is definitely soft. The sheer consistency of this mode is laudable, especially as Techland does not lean into dynamic resolution scaling to achieve this lock. As standard, both machines boot in performance mode where rendering resolution is locked to 1080p, while frame-rate targets - and doggedly locks - to 60 frames per second. It's with PS5 and Series X where things get a little more interesting. Digital Foundry's first Dying Light 2 video covers off the state of play on PlayStation 5 and Xbox Series consoles. No ray-tracing features are included on Series S either. To get the bad news out of the way first, the multiple rendering modes are not present on Series S, which is fixed to a native 1080p at 30 frames per second (and to be clear, the 30fps target is also set for the last-gen machines too - we'll be looking at those versions in the next couple of days). Even on Series S, animations, texture quality, and lighting compare favourably to PS5 and Series X - the big downside being in resolution and frame-rate. Woodland areas flow beautifully with rare signs of performance drops. Right now the question is simple: how do PlayStation 5 and Xbox Series consoles run the game? Are 30fps and 60fps modes best for play - or should you push higher for the ray tracing features? Without question, Dying Light 2 looks great on all three current-gen systems. For that, you'll need a high-end PC (where Dying Light 2 offers even more visual features) and we'll be talking about that in our next piece. Three different rendering modes are on offer on PS5 and Series X consoles, all of them delivering something desirable - but the horsepower simply isn't there to offer them all in combination. Our first impression? Dying Light 2 can look astonishing - but it's no secret that it's exceptionally heavy on the GPU. With a focus of straddling the console generations while utilising cutting-edge visuals on the latest hardware, the studio promises us a rich density in detail, seamless streaming, upgraded physics, animation and AI. Developer Techland has a reputation for delivering exceptional visuals via its own in-house technology - the C-Engine, taking centre-stage in Dying Light 2. Of course, in Coherence mode, you don’t see Windows boot in the background. After clicking Parallel’s Windows desktop icon in macOS, it’s only 15 seconds until you’re staring at the Windows 11 desktop. Put to the test, boot times for the ARM version of Windows 11 are lightning-fast. This further saves on both systems resources and battery life. It delivers a 500% faster OpenGL graphics performance and 28% faster DirectX 11 graphics performance.Īs with earlier versions of Parallels, Parallels Desktop for Mac 17 can take advantage of Travel mode to automatically pause Windows or Linux when it’s not in use. Meanwhile, a new Windows display driver supports more apps and games. When it comes to running the ARM versions of Windows 10 and 11, Parallels promises up to 33% faster boot times and 20% faster disk performance. This includes how many CPU cores and how much RAM is allocated to each virtual machine, along with which resources they can access on your Mac. If you’re not happy with that, the new resources manager gives you a lot of granular control. It automatically allocates the optimal resources for your virtual machines. To ensure the best performance, Parallels Desktop for Mac 17 sizes up your Mac’s hardware. Really, it’s the performance boost that catches your attention.Ĭoherence mode makes it look and feel like Windows applications, such as Microsoft Edge, are running on macOS. They’re mostly incremental improvements, such as adding support for USB 3.1. Unfortunately for Linux users, Parallels discontinued Linux support for Coherence a few versions ago.Īpart from this, there are no real showstopper new features. This includes support for Monterey’s new Quick Note feature. The latest version of Coherence makes a few integration improvements, such as the ability to drag and drop text and graphics between Windows and macOS applications. You can call up the Windows Start Menu from the macOS dock and even create launch icons for Windows applications in the dock. In Coherence mode, Windows applications look and feel like they’re actually running on macOS – giving you the best of both worlds. It completely blurs the lines between macOS and Windows, by hiding the Windows desktop and just showing you the Windows applications. That said, one of Parallels’ most useful features is Coherence mode, which is a bit of a mind-bender. There’s also a picture in picture mode, which keeps the virtual machine in a floating window on your Mac desktop. This makes life easier if you’re regularly switching between operating systems. You can make them full screen – perhaps on a separate desktop to help keep things straight in your head. You can run these Windows/Linux operating systems in a window on your Mac. While you need to download Windows separately from Microsoft, there’s also the built-in option to automatically download and install the latest ARM versions of Linux. You can run 32-and-64-bit Intel apps on these versions of Windows, not just Windows ARM apps. Thankfully, you can access ARM versions of Windows for free by signing up for Microsoft’s Insider Preview program. Along with a few flavours of Linux: Ubuntu, Fedora, Debian and Kail. This limits you to the ARM versions of Windows 10 and Windows 11. The most noticeable difference is that, when running on an M1 processor, Parallels Desktop for Mac 17 only supports operating systems designed for ARM processors. Even so, they offer slightly different features. It’s a universal binary download, so the single installer works on both types of Mac. Parallels Desktop for Mac 17 runs on both M1 and Intel Macs. With the demise of Boot Camp for M1-powered machines, which use ARM architecture, Mac users who need access to Windows will rely on Parallels more than ever. This runs Windows on the actual hardware rather than on an emulator. The benefit of Boot Camp is the ability to boot an Intel Mac into Windows. You can read other GadgetGuy Parallels news and reviews hereĪpple’s move away from Intel chips in favour of Apple Silicon M1 chips, such as in the latest Apple MacBook Air (M1 2020), means that new Macs will no longer support Boot Camp. Review: Parallels Desktop for Mac 17 Australian website It’s also ready to make the most of a M1 power plant under the bonnet of a new Mac. Parallels Desktop for Mac 17 supports the upcoming macOS Monterey, both letting you run Parallels on Monterey and run Monterey on Parallels. You still need to supply your own copy of the other operating systems. Keep in mind that Parallels is just a hardware emulator. In fact, it’s actually running as an application on your Mac. This lets you trick Windows, Linux or even another copy of macOS into thinking it’s running on a standalone computer. Parallels’ virtualisation software mimics hardware.
