This script helps you block or unblock a list of distracting websites, such as social media platforms, by modifying your /etc/hosts file. It can be used to increase productivity and avoid distractions.

1. Download the script and place it in a directory of your choice.
2. Open a terminal, navigate to the directory where the script is located, and run the following command to give the script execution permission:

chmod 777 block_websites.sh

3. Optionally, you can create a symbolic link to the script to make it globally accessible from anywhere in your terminal. Run the following command, replacing /path/to/your/script with the actual path to the script:

sudo ln -s /path/to/your/script/block_websites.sh /usr/local/bin/block_websites

Now you can use the block_websites command instead of the script path.

Run the following command:

sudo ./block_websites on

or, if you created a symbolic link:

sudo block_websites on

This command will block all websites listed in the arr variable inside the script by modifying the /etc/hosts file.

Run the following command:

sudo ./block_websites off

or, if you created a symbolic link:

sudo block_websites off

This command will unblock all websites listed in the arr variable by removing their entries from the /etc/hosts file.

Run the following command, replacing example.com with the actual website you want to add:

sudo ./block_websites add example.com

or, if you created a symbolic link:

sudo block_websites add example.com

This command will update the script file, adding the new website to the arr variable. To block the newly added website, run the sudo block_websites on command again.

Run the following command, replacing example.com with the actual website you want to remove:

sudo ./block_websites remove example.com

or, if you created a symbolic link:

sudo block_websites remove example.com

This command will update the script file, removing the website from the arr variable. To unblock the removed website, run the sudo block_websites off command again.
