If you find yourself spending too much time on certain websites, you may want to consider blocking them. Blocking websites can be helpful in increasing your productivity and focus. While there are many ways to block websites, using Terminal is a quick and easy way to do it.
What is Terminal?
Terminal is a utility on your Mac that provides a command line interface (CLI) to controlling the UNIX-based operating system that underlies macOS. In layman’s terms, this means that you can enter text-based commands to perform tasks on your computer. While this may sound daunting at first, using Terminal is actually quite simple once you get the hang of it.
One of the things that you can do with Terminal is block websites. This can be useful if you want to restrict yourself from accessing certain websites (e.g. Facebook, YouTube, etc.), or if you want to block certain websites for other users on your Mac. In this article, we’ll show you how to block websites on your Mac using Terminal.
How to Block Websites on Your Mac Using Terminal
If you’re looking for a way to block websites on your Mac, you can do so using the Terminal app. Blocking sites can be useful if you want to limit your own access to certain websites, or if you want to restrict access for other users of your Mac.
Here’s how to block websites on your Mac using Terminal:
1. Open the Terminal app. You can find this in the Utilities folder in your Applications folder.
2. Type in the following command, replacing “example.com” with the URL of the website you want to block: sudo nano /etc/hosts
3. Enter your password when prompted.
4. Use the arrow keys on your keyboard to scroll down to the bottom of the file that opens up in Terminal.
5. Type in the following code at the bottom of the file, replacing “example.com” with the URL of the website you want to block: 127.0.0.1 example.com
6. Press Ctrl+O on your keyboard to save your changes, and then press Enter/Return. Press Ctrl+X to exit Nano text editor.
7. Restart your computer for the changes to take effect.”
How to Unblock Websites on Your Mac Using Terminal
If you want to unblock websites on your Mac, the process is actually very simple. All you need to do is open up the Terminal application and enter a few commands.
First, you’ll need to add the website that you want to unblock to the “hosts” file. This file is located at /private/etc/hosts. To edit it, you can use the nano text editor. Type the following command into Terminal:
sudo nano /private/etc/hosts
Enter your password when prompted. Then, scroll down to the bottom of the file and add the following line:
Replace www.example with the actual URL of the website that you want to unblock. Once you’ve added the line, press Ctrl+X to exit nano, then press Y when prompted to save your changes.
The next step is to flush your DNS cache so that your computer will re-read the hosts file and start resolving URLs correctly again. For this, you can use the dscacheutil command. Type the following into Terminal:
Finally, restart your web browser and try visiting the website again — it should now be accessible!

How to Block Websites on Your Mac Using Hosts File
The hosts file is a list of mappings between hostnames and IP addresses. You can use it to block websites on your Mac.
To do this, you need to open the hosts file in a text editor. The hosts file is located at /private/etc/hosts.
In the hosts file, you will see a list of mappings, with each mapping on its own line. To block a website, you need to add a mapping for that website’s URL to the hosts file. For example, if you wanted to block Example Website, you would add the following line to the hosts file:
You can also use wildcards to block websites. For example, if you wanted to block all websites that have the .com Top Level Domain (TLD), you could add the following line to your hosts file:
Once you have made your changes to the hosts file, you need to save it and then flush your DNS cache in order for the changes to take effect. On macOS Sierra and earlier, you can flush your DNS cache by running the following command in Terminal:
sudo dscacheutil -flushcache
How to Block Websites on Your Mac Using a Web Browser Extension
There are a number of ways you can block websites on your Mac, including using a web browser extension or using the Terminal application.
If you want to block websites on your Mac using a web browser extension, we recommend the Block Site extension for Chrome or Firefox. This extension will allow you to block websites based on their URL or domain name.
To block a website using the Block Site extension, simply add the URL or domain name of the website you wish to block to the extension’s list of blocked sites. Once a site is added to the list, you will no longer be able to visit that site in your web browser.
If you want to block websites on your Mac using the Terminal application, you can do so by editing the hosts file on your computer. The hosts file is used by your computer to map hostnames (e.g., www.google.com) to IP addresses (e.g., 184.108.40.206).
To edit the hosts file on your Mac, open the Terminal application and type the following command: sudo nano /etc/hosts. This command will open the hosts file in the Nano text editor.
Once the hosts file is open, add a new line at the end of the file and type in the URL or domain name of the website you wish to block, followed by a space and then 127.0.0.1 (e.g., www.google
How to Block Websites on Your iPhone or iPad
It’s easy to block websites on your iPhone or iPad using the built-in parental controls in iOS. Just open up the Settings app and tap on Screen Time. Tap Content & Privacy Restrictions, and then tap Web Content. From there, you can choose to always allow certain websites, limit adult websites, or even completely restrict web access altogether.
How to Block Websites on Your Android Device
If you want to block websites on your Android device, there are a few different ways you can do it. You can use a third-party app, or you can use the built-in features of your web browser.
If you want to block websites using a third-party app, there are a few options available. A popular option is BlockSite, which is available for free on the Google Play Store. BlockSite allows you to block websites and apps, and also allows you to schedule when they should be blocked.
If you don’t want to use a third-party app, most web browsers have built-in features that allow you to block websites. For example, in Google Chrome, you can go to Settings > Site Settings > Block Sites and add the websites you want to block. In Mozilla Firefox, you can go to Options > Privacy & Security > Blocked Sites and add the websites you want to block.
Both of these methods should work for blocking websites on your Android device.
How to Block Websites on Your Windows Computer
To block a website on your Windows computer, you can use the hosts file. The hosts file is a text file that contains a list of IP addresses and hostnames. When you try to access a website, your computer will look up the IP address of the site in the hosts file. If it finds an entry for the site, it will block it.
To edit the hosts file, you will need to open it in a text editor. The hosts file is usually located at C:\Windows\System32\drivers\etc\hosts. You can also find it by opening the Start menu and searching for “hosts.”
Once you have opened the hosts file, you can add entries for websites that you want to block. To do this, type the IP address of the site followed by the hostname of the site. For example, to block www.example.com, you would add the following entry:
You can also use wildcards to block multiple sites at once. For example, to block all websites on the example.com domain, you could add the following entry:
