How to Block any website in MAC Os or linux

To be more productive some time you may want to block some website.  In my case sometimes I block amazon.com, amazon.in, facebook.com.

To block  website you need to edit your host file

go to terminal and type 

sudo vi /etc/hosts

It will ask for your password

in hosts file add the following line

127.0.0.1   www.facebook.com

127.0.0.1   www.amazon.com

you can add as many as you want to your host file. State above example block www.facebook.com and www.amazon.com.

You may find out some time those example not work with out reboot. In this case you need to clear  dns cache

just type following line in terminal to clear cache

dscacheutil -flushcache
